             Changelog 
            ===========

[December 2006]

scid-3.6.1-pg.1
---------------
- Modified Phalanx sources : added a setboard call, and modified io.c file
- added a new coach function : a game can be played against an engine at a given ELO rate
- game analysis can now check for blunders and not comment every move
- a setup.exe is built on windows embedding Phalanx and Crafty (thanks to R. Hyatt for authorising this). If the user
installs with default configuration, the engines are pre-configured

[January 2007]

scid-3.6.1-pg.2
---------------
- modified io.c file in Phalanx in order to get correct communication between Scid and Phalanx under Windows in analysis mode

scid-3.6.1-pg.3
---------------
- colored squares and arrows can be entered directly on board without the "comment editor" window :
   - shift + mouse button {1,2,3} for squares
   - ctrl + mouse button {1,2,3} for arrows
- removed the ability to go back one move with right mouse click : too risky because if at the end of a line it erases the last move. Use CTRL+DEL or CTRL+BACKSPACE instead.
   
scid-3.6.1-pg.4
---------------
- modified the way variants are handled : Scid can read recursive variations but the user can no longer enter
them. I will put this back if someone can tell me any use case of the VAR described at para 8.2.5 of
PGN standards (modified ::move::Back in move.tcl).
- when playing a tactical game against Phalanx, it is possible to choose which opening to train against

scid-3.6.1-pg.5
---------------
- added the French Exchange line in tactical game
- added an opening trainer in tools->training menu.

scid-3.6.1-pg.6
---------------
- added russian language : still needs feedback to see if it works
- minor bug fixes and optimizations

scid-3.6.1-pg.7
---------------
- removed a bug : move back would not allow to go back to start position (side effect of recursive var handling introduced in pg.4)
- when navigating through a game, automatically display variations. It is now possible to navigate through a game with variations only with arrow keys, which is far easier and more efficient.
- fixed a bug in ECO browser (Xunmap)
- fixed the bug occuring after a board resize when the board was flipped (dirty workaround : see resize2 proc)

scid-3.6.1-pg.8
---------------
- fixed a bug in board resize code

scid-3.6.1-pg.9
---------------
- tactical game : added a check for Phalanx engine in order to be sure the Phalanx engine chosen is the good one. Users never read manuals and instructions ... Also forbid the user to select Scidlet for analysis, as this engine as no analysis function
- fixes and updates in language files

scid-3.6.1-pg.10
----------------
- Added exercises in Tools -> Training -> Tactics : more than 20000 exercises

[February 2007]

scid-3.6.1-pg.11
----------------
- Bug fix : correctly restore askToReplaceMoves value when exiting Scid without closing tactical exercises window (file.tcl)
- put all proc and vars in isolated namespaces for tactics.tcl, tacgame.tcl and opening.tcl (may prevent some side effects, even if none occured)
- translated opening lines for tactical games (currently only translated to French in tcl/lang)
- added a config file Makefile.conf.darwin (rename it to Makefile.conf before running configure) to compile Crafty under Mac OS X (not tested)
- added extra checks in tactics in order to determine if a move is the best
- added support for display of multi-PV (multi principal variations) in order to take advantage of Toga's multi-PV feature (analysis.tcl)
- simplified the way invertScore works in analysis.tcl (the score is always from white's perspective)

scid-3.6.1-pg.12
----------------
- fixed bugs in game annotation and variations handling

scid-3.6.1-pg.13
----------------
- added partial UCI support (tested only with Toga 1.2.1)
- added MultiPV support for UCI engines, and only UCI (inapropriate for xboard engines)
- optimized the analysis board(don't enter moves when hidden)

scid-3.6.1-pg.14
----------------
- fixed a bug when an analysis window is destroyed (tried to flush an already closed pipe)
- simplified tactical games configuration (the first encountered Phalanx and Crafty engines are used)
- added an utility script removetoken.tcl to help maintain and clean up langage files

scid-3.6.1-pg.15
----------------
- fixed bugs (in makeAnalysisMove proc, in UCI promotion, etc.)
- converted UCI engine output to something more readable

scid-3.6.1-pg.16
----------------
- UCI parser (much) improved
- added dynamic UCI configuration by reading engine's published parameters
- VERY HUGE memory leak fixed (sc_game push and pop don't free game memory) 
- optimised conversion UCI -> San notation (takes 0.5 msec at each iteration)
- In repertoire trainer, value of candidate moves were always displayed : now the option (checkbox) is taken into account

scid-3.6.1-pg.17
----------------
- UCI optimisation
- Fixed UCI options parser to handle the Glaurung engine (multi-word options) and button option

scid-3.6.1-pg.18
----------------
- handled the case where an user finished all tactical exercises
- fixed bugs in lang files (opening translations used in tactical game)
- changed main line output for UCI engine (more readable)
- added ELO rating of opponent and date when playing a tactical game
- Association of PGN and Si3 files under windows
- added a book window : used a stripped version of Polyglot (PolyGlot 1.4 Copyright 2004-2006 Fabien Letouzey.)

scid-3.6.1-pg.19
----------------
- fixed a bug in auto-annotation when only one side is selected for annotation
- changed entry widgets to spinboxes in autoplay dialog
- added an option in annotate mode : a reference book can be selected, and the moves present in book are of course not analysed
- rewrite of annotation and autoplay, which was uselessly complex (and somewhat miscoded)

scid-3.6.2
----------
- Simplified Scid-pg name to Scid : wise isn't it ?
- changed year values in statistics window
- fixed a bug in UCI engine options window, not all parameters were present in combobox
- made the UCI engine configuration window a bit more readable
- fixed a bug where Hash memory to use was not always sent to the engine at a time it will really consider it
- changed opening table max number of games (spinbox from 0 to 5000)
- added a book call in tkscid : sc_book update
- added the possibility to tune by hand an opening book (useful for preparation before entering an engine tournament)

scid-3.6.3
----------
- a whole base can be analysed in batch mode
- fixed a bug in analysis : if the first move out of book is a blunder, it was not correctly annotated
- automatic finding of boob : base of opening blunders
- fixes to book annotation

scid-3.6.4
----------
- fixed a bug in display of UCI options (for example Rybka's options);
- Extra quotes were appended to engine names when there were spaces in path, preventing the start of some engines

[March 2007]

scid-3.6.5
----------
- moves displayed in book window are now clickable
- game annotation including all variations
- a branch of a book can be exported in a game (useful for book makers)
- added some help information (still needs to be completed)
- added the detection and configuration of Scorpio as an xboard engine
- changed engine init in analysis.tcl : engines that don't correctly output their features are now correctly configured (again)
- some engines don't like do get too many commands at once (like arasan). Added code to handle this.
- added a new color scheme sent by Shivkumar Shivaji
- cleaned up some code in analysis.tcl

scid-3.6.6
----------
- added clocks for tactical games
- added a button in analysis window to start / stop engine analysis
- minor bug corrections
- photos of players usually hide some comments in the game info window : the photos are now clickable wich minimizes them

scid-3.6.7
----------
- bug fix in clocks (sometimes - when following specific openings - they went out of sync)

scid-3.6.8
----------
- clicking on a clock stops or starts it
- the variations pop-up window is now clickable (a variation can now be entered either by using right arrow, enter key or mouse button)
- increased the max number of games in clipboard base to 1.000.000 (this should satisfy all needs)
- multiple PGN file import
- fixed a minor bug in tactical game when following a specific opening line

scid-3.6.9
----------
- Annotation :
   - when annotating a game for opening blunders, the Annotator tag is set to "opBlunder X (side)", where X is the move number 
   - The engine name used for annotation is appended to the Annotator tag and as a comment before inserting engine's variation
- Using third mouse button will automatically add variations without asking (entering a complex game is faster)
- EPD support :
   - added a "sc_epd load" callback in tkscid.cpp
   - EPD window displays the list of positions which are directly selectable with mouse
   - EPD file can be automatically annotated (the EPD tags used are : acd, acn, ce and pv)
- Book :
   - Book window position and size is saved / restored 
   - Added book window for auto opening at startup (menu Options -> startup)
- several fixes in language encodings and translations, added a new swedish translation file (thanks to Hans Eriksson)
- fixed a minor error in scid help file (thanks to Hans Eriksson)
- fixed a major (and old) bug in some translations files where procedure names were also translated, hence breaking some of Scid features

scid-3.6.10
----------- 
- added the possibility to play (seriously) against an UCI engine (tools->training->serious game): 
   * setting time per move and increment per move (called "serious game")
   * follow specific opening lines
   * choice between several books
- changes to user interface:
   * when resizing the configuration window of "tactical game", the list of openings is properly enlarged
   * Save windows size and position between sessions for tactical games and exercises
   * save position of the variations popup window
   * <Return> adds move of analysis engine #1
   * added a shadow under the text of tablebases diagrams to make them more visible (added an extra parameter to ::board::mark::DrawText) 
- changes to engines:
   * some code optimisation in UCI engine protocol
   * added a button in analysis window of engine #1 : engine can continue (ie play) automatically a game until the end ("demo mode")
   * fixed a bug in engine #2 handling
- user can now navigate in tactical exercises using ordinary ways to change game (game list, next/previous game menus, etc.), so it is easy to go back to any exercises to review them
- updates in help files
- In "Tools/Training/Tactics", "limit engine analysis time" is now a saved option
- fixed a bug where if variations exist at current move and the comment editor was opened, the comment was propagated to all moves (this bug did not exist in Scid 3.6.1 !)
- translations:
   * updated swedish translation and installation on windows (thanks to Hans Eriksson)
   * updated Nederland translation (thanks to Leander Laruelle)
   * added a scid_fr.eco file (french ECO file, thanks to Pascal Georges)
- and usual minor fixes...

[April 2007]

scid-3.6.11
-----------
- changed book handling : several books can be opened at the same time (in windows or for use by engines)
- it is possible to play a "serious game" from current board position (and not necessarily from start position)
- When analysing a game that is not ended by a mate, the best continuation is added as a variation (previously the annotation process would not evaluate the last move and then not give the best line)
- PGN window : next moves and variations are made visible when moving through a game (instead of just having the last move displayed at bottom). The text window is scrolled to make (if possible) all relevant information visible. 
- configuration of a serious game : added fixed depth, fixed seconds and fixed nodes per move as "time controls"
- modified Toga in order to make it more UCI compliant (ie understand "go nodes")
- added a clock for tactical exercises
- clock is stopped automatically at end of a game that ends by a mate
- added statistics on repertoire knowledge and a report on repertoire knowledge (opening trainer feature)
- added a new API call "sc_var number"
- added a contextual menu in PGN window to ease game edition (var deletion, promotion, etc.) (the menu is triggered by right mouse button and the mini board is popped up with the middle mouse button)
- bug fixes :
   * fixed a bug when the user wanted to start a game and when current opened base was a PGN file (call to sc_game save 0)
   * fixed Scidlet handling in analysis mode (this engine has no setboard or analyse modes, so it must be particularly handled)
   * fixed a bug in variations handling (certainly when the user pressed repeatedly some keys too quickly, which would trigger a race condition and an harmless exception)

scid-3.6.12
-----------
- added new spelling and rating files (thanks to Franz Nagl)
- fixed a bug in opening report that would crash (floating point exception due to a division by 0) if all games in base had a score set to *
- updated swedish translation (thanks to Hans Eriksson)
- added a "coach is watching you" in serious game (will detect dubious/weak/bad moves on the fly)
- added a "random level opponent" in tactical games
- fixed a bug in Crafty handling (regression introduced in 3.6.11)

scid-3.6.13
-----------
- fixed a bug in "en passant" moves (7r/pp3k2/2pb4/3pn1P1/P5p1/1P6/2P1NPP1/3R1RK1 w KQkq - 0 1 after f4, gxf3 was considered as illegal)
- improved non-UCI engines handling (especially for Scidlet)
- values for informant notation is now entirely configurable and will be reflected in analysis, tactical and serious games
- game annotation now uses informant symbols (+=, -/+, etc)
- added a new export file format : HTML + Javascript (games can be replayed online, small boards are added in moves frame). [Thank to Marc Lacrosse for his valuable hints, and at same time, to have proven that Anand is beatable !]
- fixed an important bug in book tuning
- put back the "delete last move" triggered by a click on right mouse button. So the use of the mouse is the following : 
   * left button : enter a move, asking for replacement, variation, etc
   * middle button : enter a new variation without asking
   * right button : delete last move if at end of var, else go back one move
- added a new pieces set : eboard (better look, colorful and in relief) [Thanks to Michal Rudolf to have pointed out the idea, and to eboard and chessx contributors]
- updated swedish translation [thanks to Hans Eriksson]

[May 2007]

scid-3.6.14
-----------
- added an option for PGN output : add spaces conforming to PGN standard. This will be reflected in every place PGN is used (PGN window, PGN export,...)
- fixed a bug (that existed since Scid 1.9 ?!) where Scid would crash importing some very particular games (played on internet), with extraordinary long comments (whispers)
- windows OS : 
   * updated inno setup and cygwin1.dll
   * by default engine starts in low priority to make UI more responsive
- the resign value is now configurable and equal to ++-
- added a draw detection by 3-fold repetition when playing tactical or serious games
- changes to engine handling (both UCI and x/winboard) so engines will be correctly started whatever position (in previous Scid releases it was necessary to move back/forth to wake up some engines). The drawback is some extra latency at start for x/winboard engines (about 1 second).
- fixed a bug in opening report where the number of games displayed was limited to 500
- fixed a bug when adding moves from UCI engines
- when an engine finishes a game (blue/grey arrow in analysis window), the function will be turned off after a mate.
- added "ponder off" command so Crafty can be started/stopped with analysis window opened
- added material balance display aside the board
- added a new annotation option "short annotations" : scores and comments (like "weak move played score changes from X to Y") will not be used but only NAG values (annotations are less verbose)
- fixed options setting for some UCI engines. Some engines don't take into account all parameters when they are sent in batch mode, so all option commands are now wrapped with "isready" and "readyok".
- added a command to opening report : "merge games", which will merge as variations the N best games to current game (with a limited ply depth) - still experimental
- updated swedish translation [thanks to Hans Eriksson]

[June 2007]

scid-3.6.15
-----------
- added an extra option to game annotation : "annotate all moves" and made some minor changes to annotation process
- added a filter on engine output (UCI engines under Wine - http://www.winehq.org - sending useless empty lines)
- after an opening report is generated, games can be merged into a game belonging to another base and all moves of the merged games are copied (instead of the first 20 moves)
- a click on analysis window (un)hides the lines : only the score is displayed
- when importing multiple PGN files, the dialog box is not closed after each completion, and information is gathered in a single window
- UCI engine options were only set in analysis mode : now it is also set when playing serious games
- updated german translation (thanks to Uwe Klimmek)
- changed the promotion dialog box to display bitmaps of the chess pieces instead of english text (nicer, and no need for translation)
- increased BBUF_SIZE so that the import of very particular games (played on internet), with extraordinary long comments (whispers) will no longer fail (of course those buffers are static and it is always possible to make games with comments so long (1 MB) that the import will still end with an error)
- tournament crosstable : a game was considered in a tournament when its date was between +/- 3 months form current game's date : the value is increased to 12 months as some tournaments last more than 3 months (computer matches, correspondence games, etc)
- updated swedish translation [thanks to Hans Eriksson]
- Improvements in UCI engine output : the conversion between long notation to short algebric notation is done in C code, instead of the old Tcl way, which could not really handle SAN, that is Nb1c3 is now correctly displayed as Nc3 (code reuse from Scid Pocket).
- added new Scid API : "sc_game setaltered [0|1]"
- tweaked GF_BLOCKSIZE and buffers handling so that a base generated with blocks of any size is compatible with bases with a block size of 32 kB (in order to ease Pocket PC compatibility). The drawback is that it can lead to very small overhead (buffer is copied and not shared for less than 1% of games read, but this is counterbalanced by a rarer dirty bit for blocks).
- Pocket PC code is merged with Scid one (use of #define WINCE), except Toga's code which is still in two separate branches (this sould be changed when I have found out if Toga should remain a separate process on Pocket PC or be a thread invoked in Tcl interpreter inside a DLL).

scid-3.6.16
-----------
- added a new option to sc_info : [sc_info pocket] will return memory info on a Pocket PC
- corrected "serious game" feature, which was broken as soon as the engine went out of opening

[August 2007]

scid-3.6.17
-----------
- corrected a bug where some games longer than 64K seemed to be correctly saved in a base, where in fact they can't be loaded again. The length of an encoded game in Scid is still encoded as an unsigned short, hence the game size limit. This limit could easily be changed (Length var in index.h) at reverse compatibility cost. The way games are saved is changed (line 7333+ of tkscid.cpp)
- corrected the Grünfled and Grünfeld Exchange lines, which were wrong (file tacgame.tcl)
- added moves announcement in "serious games" and "tactical games"
- corrected a bug when creating a new EPD file (error message pops up, and a Scid base was created instead of an EPD file)
- Added the handle of Chess Assistant Null move "Z0" (thanks to Marcin Kasperski)
- updated spelling and rating files (thanks to Franz Nagl)
- Added the possibility to play a tactical game from current position (like in serious game mode)
- When an UCI engine finds a mate it will no longer display a score like +327 but instead M 4 (white mates in 4 moves) or M -7 (black mates in 7 moves)
- updates in French translation
- added scrollbars to UCI engine options configuration so engines with huge amount of options are correctly handled (latest Fruit 2.3 for example)
- changed default piece set and colors (Alpha->Eboard, green/yellow->blue/light blue)

scid-3.6.18
-----------
- fixed a bug when importing PGN games : the date was not saved

[November 2007]

scid-3.6.19
-----------
- clean up of configuration files (thanks to Marcin Kasperski)
- books' path is now configurable through ./configure and Makefile.conf (SHAREDIR) (thanks to Marcin Kasperski)
- some code added to support Novag's chess board. This code is not finished (and will not be finished until I put a hand on a Novag Citrine), so the menu entries are hidden to the user until further notice.
- Added a new menu entry : "open base as Tree window" (a kind of shortcut that avoids switching between bases)
- Refresh of Tree window can be toggled
- A Tree window can be opened for each base through the command tools-> open base as tree. So now the meaning of "locked" for a tree window has changed. This used to mean display information of *this* base in the Tree window, but now it means, if the Tree window is locked, that closing the Tree implies closing the associated base. This seems natural because using "open base as tree" means the user wants to get a kind of "book/tree" and not really a base. So it makes sense to link base's fate to tree's one. Moreover, as a Tree window, a Graph window and a Best Games window, etc. can be opened for each base, more than 30 windows can be opened related to Trees, so the closing of a Tree window has to clean up things.
When several Tree windows are opened the top most is refreshed first, then others.
- Memory leaks fixed (particularly in Game class)
- New API : sc_tree free to release memory used by Tree windows (sc_tree search). This sould only be used for systems with low memory constraints.
- New API : sc_game truncatefree : when truncating a game, moves are freed. This sould only be used for systems with low memory constraints.
- New API : sc_info logmem : useful with checkmemlog.tcl script to detect memory leaks.
- New API : sc_var deletefree : when deleting a variation, moves are freed. This sould only be used for systems with low memory constraints.
- modified scmerge so it can take an unlimited number of input files (each separated by a carriage return) (thanks to Marcin Kasperski). Example usage :
   find . -name '*.si3' | sed s/\\.si3// | scmerge newbase -
This is necessary because shell command lines have a size limit.
- Added players' Elo in Score graph title
- removed explicit iso8859 encodings in some language files (french, italian, nederland, norks, portbr, ...), so that characters are correctly displayed in Tk widgets (like comment editor).
- added new piece sets to increase max board size (80) (Thanks to Uwe Klimmek)
- Merida piece sets reworked and added the possibility to use image files for white and black squares. See wsquare.gif and bsquare.gif in bitmaps directory (Thanks to Uwe Klimmek)
- added menu entries and shortcuts (F2 and F3) to directly starts engines (Thanks to Uwe Klimmek)
- increased list limit to 1000 in tourney window
- increased stats window info (Thanks to Uwe Klimmek)
- when annotating a game, the engine's name may contain "-" or "+" (Rybka for example) which will confuse the parsing of scores inside comments. So those characters are now replaced with spaces in comments, and the score graph window will correctly display info.
- added an option in the score graph window : if the scores are not related to white's point of view, it is possible to check either "white" or "black" option to get a correct display (Thanks to Uwe Klimmek)
- updated spelling and rating files : july 2007 (thanks to Franz Nagl)
- directories for books and training bases are configurable (options menu)
- minor fixes

scid-3.6.20
-----------
- Maintenance release : ECO file was corrupted in Windows binary release.
- When in a variation, left arrow no longer exits the variation (z key must be pressed to leave variation). That way it is possible to enter a comment at the beginning of a line (before the first move). Good side effect : this fixes a bug when a comment will be duplicated if entered at first move of a line and the back button is pressed while comment editor is opened.

[Jan 2008]
scid-3.6.21
-----------
- Bug fix : store comment before displaying vars window
- Engine's name in Annotator tag : optional now
- New option in annotation configuration dialog when "short annotations" are selected : add score with Nag codes
- Board coordinates can be hidden, displayed on 2 sides or 4 sides (Thanks to Uwe Klimmek)
- Modifications to filter graph and added another filer graph with absolute numbers (Thanks to Uwe Klimmek)
- added two new piece set : Fantasy & Fantasy2 by Maurizio Monge (Thanks to Uwe Klimmek)
- added a new Merida2 piece set with outlined pieces (Thanks to Alexander Wagner)
- added a new Kingdom piece set (from jin)
- Output of UCI engine is converted to SAN when multipv is 1 
- updated swedish translation (thanks to Hans Eriksson)
- Added an option in graph filter to switch the method used to determine players' ELO (estimated or not)
- Added translations to formerly english only code and updates to german help (thanks to Uwe Klimmek)
- updates to German and French translations
- updated swedish translation (thanks to Hans Eriksson)
- fixed a bug in Tree cache which was not always saved
- added two new menus to Tree window : the cache can be automatically filled for moves in a game or for all games in a base (this includes all variations).
- Tree cache sizes are now user configurable from 250 positions to 10000 (previous cache is reseted if the cache size decreased, it is left intact if the size increases).
- added a new call sc_info language <lang>, which will translate pieces to user's language (for example in PGN window, in Tree window, etc). Currently supported languages are french, german, spanish, italian, czech and nederland. Other languages will keep english pieces abreviation. This option can be turned off in options->moves menu.
- added photos of the top 100 players available at fide.com. Thanks to the FIDE for allowing the reuse of photos available at their site and to Uwe Klimmek for the compilation and name corrections (which involves a new API "sc_name retrievename").
- UCI engine configuration : some engines, like Shredder use options starting with UCI_ that should be ignored, but that in fact are important for the user : added a list in uci.tcl to keep those options.
- updated Crafty to version 21.6
- added 106 logos of engines, which are displayed in infopanel and in player info window (Thanks to Uwe Klimmek for coding this and to Wilhelm Hudetz for the logos).
- In "serious game" training, the engine has an extra option (permanent thinking a.k.a. ponder)
- Added the possibility to play on internet (FICS fresschess.org)
- minor fixes

scid-3.6.22
-----------
- ratings and spelling files from Franz Nagl are made available separately to limit Scid's package size
- added support for Novag Citrine
- fixed a bug when closing a base (players names update broken due to sc_name retrievename)

[Apr 2008]
scid-3.6.23
-----------
- updated swedish translation (thanks to Hans Eriksson)
- added piece letters translation for hungarian, norvegian and swedish
- exporting to PGN uses english piece letters
- GF_BLOCKSIZE was increased in Scid 3.6.15, but it has more drawbacks (the most important being that operations on PGN tags are 8 times slower during base maintenance) than benefits (block size has to be increased in order to save games over 32 kB). So I put back old values and used Pocket PC code to handle games overlapping blocks and to achieve compatibility between releases.
- the default engine for tactical exercises is now Toga, simplifying code
- Open base as tree has been moved from Tools menu to File menu
- updated swedish translation (thanks to Hans Eriksson)
- fixed a bug in Internet play : position was re-entered from FEN after each move (making PGN window useless)
- added NAG symbols conversion to LaTeX (thanks to W.van den Akker)
- fixed serious game play where 3 fold repetition detection was incorrect
- fixed internet play where FICS flagged bxc6 Bxc6 as ambiguous moves
- fixed a bug in tactical training : on Windows the "abort" button sometimes lead to a frozen dialog
- analysis window : to hide moves, press right mouse button instead of left button (allows copy/paste of lines)
- Functions commented out for this release (see PG3623 tags in source code : only menus are commented out):
    * Added correspondance chess support (thanks to Alexander Wagner)
    * External board support (DGT)

[June 2008]

scid-3.6.24
-----------
- added an option menu for Tree windows : Fast Mode. This will dramatically reduce the time needed to refresh the tree window but will not handle some transpositions. It is efficient only if the following procedure is followed :
   * Sort the database by ECO code
   * Compact the database
   * Fill the cache of the database (Tree window menu)
  using "fast mode" has no drawback on the cache used and the cache data saved is the one that calculates transpositions. This speed enhancement is only useful on system with low RAM compared to database size (for example 1 GB of RAM for a base containing 3 millions games).
- most used shortcuts are available from all windows (arrows, F2, F3, etc).
- engine window is compacted and use toolbar-like buttons with tooltips, making room usage more efficient. The escape button closes the window.
- when searching games with ECO code, games with no ECO code are not included by default
- ECO lines are translated in search by header dialog
- removed the frame showing material balance except for the main board
- Added move annoucements when playing on Internet (a simple move is always played when the opponent moves)
- FICS play : the graph of game offers is added (inspired by JIN), and Time seal is supported (timeseal exec must be installed). When observing a game, previous played moves are retrieved from server.
- reworked Merida and Fantasy piece sets so that there is no aliasing problem (requires package Img, which should be present everywhere)
- Fixed a bug (many years old) in Twin games detection : the parameter "Always keep games with variations" was hidden, hence always ON, preventing deletion of twins  
- changes in code (menus, changes in Crafty) to help compile Scid under Mac Os (thanks to Garth Corral)
- Engine priority is idle by default on Windows and on other platforms latest setting is kept, but resetted after each start of Scid or there would be no mean to get back to a normal priority on Linux
- minor bug fixes and enhancements :
   * Changes in crosstable and tourney finders : hope this will make them more accurate
   * Header search. 'Defaults' did not reset 'Side to move'
   *  Click on any line in ECO browser : used to replace game without asking
   * changed sizes of photos of players when clicking on them 
   * fixed "coach is watching" that would not detect user's blunders
   * show variations window improved
   * up arrow leaves current variation if at start of variation (like z shorcut)
   * Fix XML decoding issue for CC (special chars like ' & < > " etc.)
   * Fixed a bug in opening trainer (due to pieces translation)
   * Fixed a bug in scmerge
- Correspondence chess: feature complete. xfcc is done internally or via external tools, email chess is handled by external mail programs, sychronisation of either input against a specific local DB, help pages added, automatic setup added, xfcc config dialog available.
- Pocket PC :
   * Memory optimisation : will spare 800 kB to 1 MB
   * Most widgets are now themable (note that some themes don't work well with some resolutions : it is up to the user to make his choice).
   * Search headers and board completely reworked
   * Greko 5.7
- Correspondence Chess: Hook up window with scids internal geometry manager and add some optional Xfcc flags provided by SchemingMind in near future (player countries, FIDE and ICCF-IDs).
- Fix bug in email chess which sent the annotated game to your opponent.
- Hardened the code in sc_base_open so in case of failure in opening a base, things are cleaned up (most of the code concerns Scid Pocket, but some is also used for PC version).
- updated swedish translation (thanks to Hans Eriksson)
- updated spanish translation (thanks to Benigno Hernández)

[September 2008]

scid-3.6.25
-----------
- Opening trainer : 
   * automatic switch to clipbase
   * trainer window made easier to understand
- Removed Crafty engine, as tacgame.tcl does not need it any longer. So the two mandatory engines for Scid's features are Toga and Phalanx. Note that any Toga version should work, but only the patched version of Phalanx works.
- Correspondence Chess: 
   * do not drop a comment from the move list if one is sent via message.
   * Add a visual indicator to the game list if a comment was sent by the opponent.
   * Sort the game list by Site, Event, Round, Result, White, Black
   * Add highlighting in game list
   * Add tooltips for buttons
   * Add tooltip with last message sent with the game (if any)
   * Add tooltips for columns likely to be shortened (id, event, site)
   * Add Tooltip translations for english and german
   * Add basic game info for Resign/Draw (assign/offer/accept)
   * Add Scrollbar for gamelist
   * Add extensive icons/indicators help
   * Add icon/indicators help button
   * Add binding for ? to access icons/statusindicators help
   * Save and Restore Xfcc game parameters (who has the move, messages etc.)
   * Add visual indicator if Xfcc parameters were recently retrieved
     or are restored from previous fetches
   * Show time of last Xfcc update from server
   * Update help files
   * Mark games with moves sent recently in green till the next update
   * Disable invalid menue entries in eMail chess (Draw/Resign handling)
   * remove Next/Prev buttons, they're no longer usefull
- Added "sc_game push copyfast" call that behaves like "sc_game push copy" except there is no memory leak and tags and comments are not copied in the new pushed game.
- Minor bug fixes :
   * tactical game against Phalanx (some info was missing)
   * replacing a game with flags : all flags were not copied (for example tactical flag)
   * error recovery code if the network drops when playing on FICS
   * when deleting the last move of a variation by right clicking on board, the empty variation is removed
   * fixed pgnscid so importing a game over 32 kB does not lead to a segfault (but will output : Fatal error encoding game!)
   * GAME EDITOR : with comment editor opened, browsing a game would flagged it as "to be saved", even if there was no change in NAGS and comment values
   * fixed tooltip display bug on MacOs (thanks to Israel Chauca)
   * when info is available, the first line of engine window displays mate distance
   * in case of engines not configured for some training stuff, added relevant error messages
   * fixes on Tooltips display (max width, better placement, auto hide of the tooltip after few seconds, clicking on a tooltip hides it)
   * it is no longer possible to add NAG codes before the first move of a game or of a variation
   * when truncating a game, it is flagged as altered so the user will be prompted to save it
   * PGN window with short header ON. If strip first moves -> the game was displayed incorrectly as empty
   * The middle mouse button pops up a mini board in PGN window. The position was wrong when the game contains comments : fixed by stripping comments before calling "sc_pos pgnBoard" (a small bug that was many years old !)
   * After adding variations calculated by an engine, the engine used to restart calculating from scratch
- Annotation : added an option "mark tactical exercises". The tactical flag will be set to the game and a comment with ****d<depth>sc<score>. This option is only available when annotating with an UCI engine.
- Training : find best move. Will go to the next tactical position marked with 4 stars (****). See "mark tactical exercises" in Annotation feature. Pressing the right mouse button on "goto last move" (">>") button will go to next tactical exercises. A training base of over 1500 games has been released (not included in Scid package).
- added extra options to "sc_pos analyze" :
   * -mindepth. So if the thinking time is short, engine will not analyze for at least depth 4 (previous behavior), but to mindepth value.
   * -searchdepth : maximum depth of thinking
- Analysis Window new features:
   * new button "Show Engine Info" to add an extra line with the info returned by the engine (there is a button to hide/show it, works only with uci engines)
   * new "Add all variations" button to add to the current game all the multiPV variations of the engine (works only for uci engines)
   * now the "Add variation(s)" buttons work even at the end of a game (workaround, the variations are added one move before and the last game move is appended at the beginning of every variation)
   * when a variation is added from analysis window, also the engine name is added
   * the analysis window switches automatically to history mode when multipv = 1 (like in the 3.6.23 version)
   * added the max move number indicator to the current move number (works badly with some engines that don't send the "info currmovenumber" string back to gui regularly, we have to wait some time to see the right value)
   * new "Lock Engine" button (the engine keeps analysing the current position even if the user changes the position on the board)
   * reordered the buttons on the right side of the window
   * F4 and F5 starts/stops analysis of engines 1 and 2, respectively.
- The uci option window is now more large when it opens, in order to contain all the option of an engine.
- Completed translations of every pending label in italian language file.
- Fixed the help messages for some tools menus, probably wrong due to a new menu item added in 3.6.24 version (changed the code so that now it's not needed to change all menu indexes for help messages whenever a new menu is added).
- Finder : added a contextual menu (right mouse button to copy, move, delete and backup bases).
- updated swedish translation (thanks to Hans Eriksson)
- Added the scanning of filter files (.sso) from the command line (i.e. scid mydb myfilter, scid opens immediatly with mydb filtered by myfilter file)
- Tuned the startup communication between scid and engines
- Rybka 3 supported despite a small bug in its command line parser
- Scid-engine log files: maxsize to 5000 lines (was 500) and flush on every put (to aid problem detection when an engine crashes)
- Training - Serious game : 
   * UCI options of engines are now sent, so if an engine has for example an UCI_Elo present and set up, playing a serious game will be done in fact with a weakened engine (then similar to Tactical game that is designed solely for Phalanx usage).
   * added a "Configure engine" button to tweak an engine before playing (style, strength for example)
- UCI engine configuration : spinbox entries are now user writable (a check is done to ensure input is correct) and UCI checkbox is ON by default when creating a new engine entry
- UCI engine output :
  * display mate indicator in multi variations (M5 instead of +327.00) (thanks to Benigno Hernández)
  * added move numbers in multi variation lines
- Tree window : added the ability to view a tree through a mask (or layer) that contains user defined data (NAG codes, color markers, comments)
  * visible only if a Mask file (*.msk) is opened
  * the mask can be automatically with a game (as much data as possible will be imported, like variations, NAG codes, comments)
- Tree window : scores are highlighted when the moves have good or bad results
   * On average white should score 53.8%
   Parameter : set scoreHighlight_WhiteExpectedScoreBonus 3.8 ; # on average white achieves a score of 53.8
   * Check only if at least 15 games played
   Parameter set scoreHighlight_MinGames 15
   * Highlight score if score is -3 % (red) or +3% (green) from expected score
   Parameter set scoreHighlight_Margin 3.0 ; # if +/- this value, something special happened
- updated spanish translation (thanks to Benigno Hernández)
- [inhibited] support for online endgame tablebases (up to 6 men tablebases) for Scid PC and Scid Pocket : sites like http://k4it.de and Schredder does not allow queries on their site from other chess applications (even if there is no particular mechanism preventing this). So the code is commented out until a free site offering this service is found.
- MacOS : support for drag and drop of files (thanks to Israel Chauca)
- New menu entry in Maintenance menu to repair corrupted bases (equivalent to "scidt -N" in command line)

[October 2009 ]

scid-3.6.26
-----------
- Correspondence chess :
  * Fix: Variant games were not removed correctly from the inbox on Windows
  * Fix: clicking beyond the last game in the cc list caused an error
- Confirm / discard dialog box : rewritten to look a little bit better
- photos of players are now also searched in Scid shared directory (under photos directory) (Thanks to Mikhail Kalenkov)
- if "Strip out coloured square/arrow codes" is checked and PGN display is in color, comments are no longer surrounded with {} 
- PGN window : removed extra lines between moves and comments
- After closing a base, the current game is reseted
- After game searches (header, material or board), the first game of the filter is automatically loaded
- Fix : trying to repair a base already opened is now prohibited
- Fix : trying to play a tactical game with Phalanx absent would pop an uncaught exception (translation missing)
- Partial support for Tk 8.5 added
- Play on internet : a digital clock is displayed inside the analog clock (seems required for blitz games)
- Windows release : Tcl/Tk is upgraded to version 8.5, so latest piece sets (with transparency effects) are correctly displayed
- Fix : Scid could crash when generating an opening report from a huge base from particular positions. Bug introduced with Scid 3.6.21 and fixed now (buffer overflow due to moves translation in OpLine::PrintMove)
- Pocket PC : 
	* Greko upgraded to 5.9 and then to 6.0 ... (5.7.1 and 5.9 versions were buggy)
	* Scidlet added as new engine (also added xboard commands "analyze" and "exit" to Scidlet, but only for the PPC version)
	* Fix : manual draw adjudication when insufficient material (waited for ever for bestmove reply)
	* added insufficient material detection during engines tournament
- Fix : when playing on FICS or using a Novag Citrine board, entering moves with the keyboard was not sent
- Fix : mouse position on squares was inaccurate (if border size was not set to 2), and entering moves sometimes difficult (see ::board::getSquare)
- Fix : exception handled after closing FICS window, and offers graph opened
- Fix : tactical game. When aborting a game, the engine used as coach is now correctly stopped. This previously could lead to an UI freeze in some cases.
- Tactical game : reworked user interface and some enhancements : parameters saving, ability to go back in game (thanks to Steven Atkinson)
- Serious game : reworked user interface (thanks to Steven Atkinson)
- Fix : Tree window 
	* abort refreshing before closing the window
	* after a search with Tree window opened for current base, don't load automatically the first game in filter, or the Tree will be refreshed, overwriting the filter
- updated spanish translation (thanks to Benigno Hernández)
- updated swedish translation (thanks to Hans Eriksson)
- Fix : finder (Unix systems) : backup of PGN files with upper case extension

[March 2009 ]

scid-3.7
-----------
- This release requires Tcl/Tk 8.5 or higher
- Fix : Game annotation, annotating all moves : when the next move was the expected one (calculated by the engine), no annotation was added, which was not coherent with "annotate all moves"
- Reworked board setup dialog (thanks to Steven Atkinson)
- Correspondence chess :
  * Parse "TimeControl" and show in tooltip if it is sent by the server

  * Deleted games are now ignored in search of a sync-target.
  * Fix: offline state file kept growing infinitely
  * Cancelled games now no longer show up in the games list (suggested by Austin and wyb)

	* added menu entry to remove NAG value for a move
	* added entry in popup menu to enter moves not present in Tree
	* In training mode, game is annotated if the user made poor moves (related to values in Mask)
- Book tuning : 
	* any move can be added to a polyglot book at a given position (thanks to Michel Van den Bergh)
	* moves present in the book at ply N+1 but where the previous move is not present at ply N, is displayed in the lower part of the book window : see button "other moves" and its tooltip (thanks to Michel Van den Bergh)
- Plenty of changes in user interface, among others :
	* New entry in "options -> windows" to show / hide game info panel (this can also be triggered in docked mode by using main board tab)
	* New option-> Themes (only small parts of Scid are themable, this will be increased in the future)

	* Windows can be docked inside a main window (options menu) : In docked mode, the most important windows are embedded into a main one. The windows can be reordered by right-clicking on the tab (where the title of the window is) and by dragging tabs from one notebook to another. The menu for each window that has one (marked with a triangle at the left of the tab) is opened by left cliking on the tab.
- updated dutch translation (thanks to Michel Van den Bergh)
- updated spanish translation (thanks to Benigno Hernández)
- Fix : Tree window : when a Mask is opened, the whole line is clickable (not only the part with moves and stats)
- EPD:
  * UCI lines are now written in the usual formatted form
  * acs is added as resulted from the analysis
- FICS:
  * console : autoscrolling is turned off if the view is not located at the end of the text

- Tree window : when a Tree is updated and the current base is not the Tree's one, the Tree base will automatically load the first game in the filter (so by switching to the Tree's base, the position is already set to the previous one and for example an Opening report can be immediately generated)
- Import clipboard as game : on Unix systems the X selection is pasted only if the clipboard is empty
- MacOS : various updates (better support, among them the switch of mouse buttons 2 & 3) (thanks to Israel Chauca Fuentes)

[April 2009 ]

scid-3.7.2
-----------
- Fixes:
	* Small bug when closing ECO graph window (missing cleanup)
	* add missing global shortcuts
	* Bug when changing board pieces while the board was flipped
	* Closing a locked Tree window : the base switch was incomplete.
	* Bug with cursor handling (triggered for example by opening the tree window, the tree help and issuing the fill cache command)
	* Board auto resize while toggling game info display
	* Bug in "Calculation of variations" training (aka Stoyko exercise)
	* wrong assignments to ::CorrespondenceChess::num corrected
	* Game annotation : fixed a wrong NAG code (used -= instead of the correct =+)
	* Fixed menu in opening report window (docked mode)
	* FEN pasting : reversed CLIPBOARD and PRIMARY (file edit.tcl)
	* Endgame tablebase window cleanup when closing (remove its tab)
	* Twin checker : loads the first pair of twin games (thanks to  J. Wesley Cleveland)  
	* when no book is found, handle this case correctly (Book window, serious game, ...)
	* Comment editor window taking a lot of CPU under Windows 
- FICS : user interface improvements : 
	* click on a game to observe it
	* redesign in notebook style
	* better looking "offers" graph
	* used icons from http://webdesignledger.com/freebies/21-best-icon-sets-for-designing-web-apps
	* added a check box to enable standard user variables
- Correspondence Chess:
	* Add confirmation dialogue of CC moves. (Suggested by Dhanish)
	* Add copy cc games list to clipboard. (Suggested by Dhanish)
	* Add Ctrl-Up/Down scrolling through games. (Suggested by Dhanish)
	* Ctrl-F12 now also processes the inbox automatically. (Suggested by Dhanish)
	* Check if mainline is longer then the games mainline, eg. due to a users error (Suggested by Dhanish)
	* Disable engine analysis in games that do not allow it,  ie. Xfcc noEngines = true. If noEngines is not set assume "engines allowed" (ICCF). (Suggested by Austin)
	* Strip of text in [] when sending game comments
	* Show start date for individual challenges in tooltip
- Spell checker : enhanced user feedback, operation can be cancelled, all names corrected instead of the first 2000 (thanks to Joost Hart)
- Search 
	* Header: Allow to search for the special player !me which is mapped to all Playernames defined in Options / Chessboard / My Player names (can be combined with all other header search options as well as saved as search)
	* Header: Allow to search for the special player !mymove. Similar to !me but the player has to have the move at the end of the game.
	* Position: added the possibility to search for current position in another opened base (this avoids the use of the Tree window that can also be used for this, but can be found less convenient).
- User interface:
	* blindfold play (piece set)
	* Add SAA/CUA hotkeys for clipboard (Ctrl-Ins, Shift-Ins)
	* try for www-browser as generic web browser (thanks to Tiurgin)

- Translations:
	* hungarian updated (thanks to Szőts Gábor)
	* swedish updated (thanks to Hans Eriksson)

- Game merging : it is now possible to merge directly a game from one base to the current game in another base (see context menu in Game list window)
- Engines handling : 
	* renamed Phalanx-XII to phalanx-scid (as Phalanx is no longer maintained we need a way to differentiate them)
	* try to auto-configure engines (scidlet, toga and phalanx) (thanks to Israel Chauca)
- Game annotation : book to use is saved (defaults to same book as Book window)
- HTML export of games (HTML + Javascript) : improved output, better piece sets, no frames (thanks to Charly Founes) 
- Novag Citrine support : improved interface

[April 2009 ]

scid-3.7.3

 =============================================================================
- Fixes :
---------
	* serious game play when use book is checked and book name is empty leads to crash (thanks to Benigno Hernández)
	* Check for engines allowed in eMail games caused an exception (noENG not set)
	* Internet play (FICS) : 
	  - the first offer not displayed on the graph
		- hardened the code to avoid the (rare) case where the opponent moves but Scid does not reflect it. Still the need to see wether it is a FICS bug or a Scid one.
		- IP address of FICS server is cached (faster login)
		- in case of a network error, quit FICS without popping tons of error messages
	* Sound : when another application uses the sound device and once it is released, forces Scid to reset pending sounds hence be able to use sounds again (this has the drawback of limiting maximum sound length to 5 seconds)
	* Move annoucement : if pieces are translated, announces moves using english sounds (as only english annoucements are supported)
	* Tree window : fixed game loading from browse game window (when the Tree was not locked)
	* fixed status bar detailing some menu entries
	* fixed context menu in notebook tabs for FICS window
	* fixed a bug selecting more than 3 times an empty square : entering a move with this square as target was difficult (lower in ::board::colorSquare)
	* fixed the contextual menu in Mask for the command "Add this move to mask" (display all the possible moves in several menus to fit in screen's height)
	* Display best games list in Tree : fixed a game not displayed in the listbox if containing the character '
	* FIX: Display draw offers in CC games
	* Player finder window : increased entry fields for number of games (10000 is sufficient for human players but not for engines)
	* when using a Novag Citrine board, the referee mode selected is saved
	* cleaned up code for Scid versions 2.x (don't think anybody still uses it)
	* Scid no longer crashes when importing a very long game (current limit is still 32 kB)
	* Code optimisation in I/O and memory copies. For example stripping PGN Tags is 3 times faster 
	* Right mouse button takes back a move. It used to also delete the last move of a line. This is inhibited now as there is no possible undo, and the user can have triggered this function by error. 
	* Game export to HTML + Javascript : export comment before first move, fixed a problem when exporting some variations (which were stripped)
	* Comment editor : avoid the repetition of last comment when entering a new variation (see line 1235 of main.tcl)
	* Fixed menus when Scid is compiled without endgame tablebases support (thanks to Vlastimil Babula)
	* Under non windows systems, no longer try to kill an UCI engine after the quit command has been sent to it. This is necessary for Rybka 3 multiple CPU engine that spawns processes instead of threads (killing the main process before it has the possibility to stop the sub processes may leave processes eating CPU)
- Features :
------------
	* New base format :
		- import games with a length (encoded) up to 128 kB
		- 6 new user customizable flags
		- any base opened in version 3 will be automatically converted to new format in a few seconds (.si3 file is converted to .si4 and then removed, .sg3 and sn3 files are renamed respectively to .sg4 and .sn4)
	* NAG support : add symbolic NAGs using UTF-8 symbols
	* Search position : if the search is done in a refrerence base (not the current one), don't switch to it if the result returns no game
	* Tree mask : 
		- added a sub-menu for searching positions in a mask depending upon various criteria (comments, NAG, color, etc.)
		- added a sub-menu for displaying the Mask content in a tree form
		- remember the most recent opened masks
		- new moves can be added to a mask even if there is no corresponding position in the Tree 
	* FICS : 
		- save options for finding opponents based on login
		- display forecast of win / draw / loss score (in fact sends assess when creating the game)
	* Highlight last move played (switchable and configurable in options menu)
	* added a new call "sc_game info nextMoveUCI"
	* new feature to review game. The user guesses moves played from one side of a played game.
	* game browser : automatically flip board if the main board is flipped
	* updated Scid icon (thanks to Israel Chauca Fuentes)
	* First version of VIAF/PND support for hooking up Wikipedia et al.
	* Corresponden	ce Chess:
		- Sorting of the gamelist  by various criteria like own clock, opponent clock (Xfcc only)
		- Do not show games where the player does not have the move (Xfcc only)
		- Add GUI to set sort criteria
		- Implement sort by "time per move till next TC" including the next timing period (Suggested by Dhanish)
		- Add Edit menu to cc window
- Translations:
---------------
	* updated spanish translation (thanks to Benigno Hernández)

scid-4.1
========
- Features :
------------
- Added the display of arrows when several variations are available. The display can be toggled using the menu Options -> Moves -> Show arrows for variations (Thanks to Fulvio)
- When playing a move already existing in a variation, the variation is automatically entered into. To add a new variation starting with the same move, the menu Edit-> Add variation must be used (Thanks to Fulvio)
- Added undo feature (10 undos max). Shortcut is Ctrl-z. 
    For coders : rollback points are set by calling {sc_game undoPoint} in Tcl or sc_game_save_for_undo() in C++.
- Updated Scid Pocket to new base format (version 4). Version 4.1 includes Robbolito chess engine, which is by far the best of all ! Really impressive. It outweighs all other engines on Pocket PC.
- Fixes :
---------
- entering comments for last move of a line was broken
- setting the blunder flag from maintenance window was broken ("?" was considered part of a regular expression)
- when compacting a game file, custom flags description was lost
- custom flags description are now commited to index file as soon as they are modified
- Informant values were overwritten by default values at startup
- UCI engines : send "go infinite" instead of "go infinite ponder" because it is not handled correctly by some engines and "go infinite" seems sufficient
- fixed a bug when USCF piece set was selected and the library tkimg not installed (under Linux)
- UI may be unresponsive when an engine outputs lots of garbage when nearing a mate. Fixed for UCI engines only as I don't have an example of such misbehaviour of an xboard engine.
- Fixed a possible buffer overflow when parsing a malformed PGN (Thanks to Fulvio)
- Modified slightly UCI parser in order to get Prodeo to work (there's no garantee that Prodeo will work as it does not comply to UCI protocol) (Thanks to Shiv Shivaji)
- Fixed an error popping up when pressing right arrow very quickly with the variations window displayed and engines taking all available CPU
- Fixed impossibility of stripping comments and variations when display of short headers was turned on.
- Rewrite of "Review game" code : moves are no longer in comments, engine analysis is updated more often

scid-4.2
==========
- Features :
------------
- Training -> Find best move : make it more user friendly :
	* The next moves are automaticaly hidden in PGN window and in game info window
	* Added buttons above the board to show solution, go to next / previous exercise
	* Leave the training mode by unchecking the menu entry
- updated swedish translation (thanks to Hans Eriksson)
- updated spanish translation (thanks to Pedro Reina)
- Scid Pocket : added Stockfish 1.6.2 ported to ARM (Windows Mobile)
- Fixes :
---------
- Scid has a limit of 16 millions games per base. Before reaching this limit, the size of the game file could exceed 2 GB, which was not possible on 32 bit systems. So now some of Scid's IO handle large files (64 bit I/O system calls even on 32 bit systems) (but the limit for the game file is still 4 GB, given that games offsets are saved as unsigned integers). So now it is possible to have bases that effectively contain up to 16 M games.
- FIDE changed the number of rating list per year. Add code to handle this properly. Maximum year for ratings added by spellchecker is _2010_. (Thanks to Joost 't Hart)
- Searching for !me (own games) was broken
- Xfcc passwords with XML entities were not handled correctly

scid-4.2.2
==========
This maintenance release reverts to 32 bits file I/O. Large file handling across many platforms seems a bit hard too achieve ...

[xxxx 2010 ]
scid-4.3
==========
- Mark the Repertoir Editor deprecated, guide users to Masks
- Improvements
	* documentation for opening trainer (thanks to Dale Hards)
	* Some of the programs icons based on GNOME Stock Icons in case png-support is available
	* Refresh icons for Database switcher (Thanks to Peter Wong and Steven)
	* Some defaults of Scids empty config
	* Gamelist: show delete-flag to the very left of the list by default
	* Taller information field (Thanks ot Milan Zamazal and Gerd Lorscheid)
	* Replace some buttons in help by proper img tags
	* Bring Best games / tree graph to front if they exist and the button is pressed again
	* Toggle autoplay mode was mapped to Ctrl-z instead of Ctrl-Z so it confliced with undo
	* Speed improvement for game copy operation
	* New checking option for games consistency
	* Improve proportions of USCF piece set
	* HTML export
	    - Move nags rendered in same font as the move
	    - Diagram immediately follows the move (order of diagram and comments are swapped), which is a more common scenario
	    - Indentation of variations enhanced by putting them in indented div sections
	    - Current move hightlighting, board and diagram colors follow css style definition
	    - Cursor key navigation works in IE
	    - Cursor left key navigation works the same way backwards as right works its way forwards, i.e. skipping variations
	    - Dotted move numbers for black moves in a main line are also applied following a diagram and a variation.
	* Annotation/analysis
	    - Added engine thinking time to annotator string
	    - Stop engine at end of annotation
	    - UCI engine: Added notion of length of mating line to cp score (shorter is better)
	    - Added annotation at end of variations
	    - Added depth to variation scores
	    - Added option to score all moves (also those which are not annotated)
	    - Removed option to annotate only not-best-moves, as it is no longer usefull now
	      all-moves does no longer produce lines starting with the played move
	    - Increased maximum engine thinking time to 999 [sec]
	    - Removed the blunder signature in the annotation (as we cannot tell how sharp the threshold is)
	    - Added variation times in multi-pv mode
	    - If game just follows book till some book end, last book move does not need analysis.
	    - Blunder-check annotation spots faster mates, regardless of threshold.
	    - Annotation adds - in all modes - a '?!' nag if the main move is significantly (informant value)
	      stronger than the best move the engine expected.
		 - Finish game now allows for a shootout between two UCI engines
			if two engines are opened.
	* PGN import always opened in Scids bin folder, now use last dir instead and store it.
	* Mask files folder location gets stored and reused
- New features:
	* Correspondence Chess:
		- Allow observation of games on ICCF webchess
		- Add connector file support to configure game relay from the internet
		- Make dialogues etc. theme aware for Tk 8.5
		- Allow for postal games by the Mode "Postal" header. Those
		  games are not touched but show up in the cc window provided a
		  suitable PGN is present in the Inbox. (ICCF might generate this
		  in case of mixed events.)
		- Add two new headers: WhiteAddress / BlackAddress to hold
		  postal adresses for eventual postcard printing
		- Read additional header tags from the database and thus allow
		  to show e.g. flags if Black/WhiteCountry header is set even if
		  those tags are not provided by the games in the Inbox
		- Rewrite of some parts of the update procedure
		- Code cleanup and performance improvements
		- Allow scrolling of the CC gamelist by keyboard (PgUp/PgDn, Up/Down)
	* Show WhiteCountry/BlackCountry in game info area
	* Initial support for bibliographic links in PGN headers:
		- A BibTeX-file either named $scidDataDir/Bookshelf.bib or named and located along with the current database is parsed as bibliographic input
		- Header lines of the form [Bib "<bibtexkey>, <addinfo> ; <bibtexkey>, <addinfo>"]
		  open a new window with bibliographic reference; <addinfo> e.g. No.27 p.85.
		- if Bib-header exists a new link shows up in game info area
		- To handle the bibliographic database 3rd party tools can be
		  used. A valuabe free, open source  solution might be
		  http://jabref.sf.net (or any other bibliography tool for BibTeX)
	* Best games list:
		- For annotated games (NAGs, Comments, Variations) show an A in the list
		- For flagged games show up to 4 flag chars or the number of
		  flags if there are more than 4 flags present.
		- Obeys a filter set by header search
	* Allow to change the board without waiting for tree windows to complete search. (Thanks to Fulvio)
	* Rework ID linking code
		- Tags, resolverurls, icons etc. are read from a config file.
		  This eases up future extensions of IDs known by Scid
		- If no config exists create a default one handling FIDE, ICCF, DSB, BCF, VIAF, SM
		- Each ID has to link to a unique page, multiple links are not possible
		- PND is still special as it is used to link to various complex
		  locations like Wikipedia (including NLS) and SeeAlso. This is
		  still treated internally
	* Comment editor
		 - now opens by clicking the comment in game info area
		 - Make board toggable by either alt-b or button and save its state
		 - recognises Ctrl-A for adding a new variation => easy addition for pre move comments
		 - Alt-Left/Alt-Right now go one move backward/forward
		 - Map Alt-N to switch between NAG- and text entry
		 - Autostore comments as soon as the window looses focus
	    - Add Ctrl-N shortcut to Edit window to call NAG values help
	    - Add "Open Comment editor" to PGN context menu
	    - Add common NAG symbols to PGN context menu (Thanks to G. Lorscheid)
		 - Comment editor can be opend by the small light bulb button in
		   the toolbar. This button also signifies if the game already
		   contains commentary in the current position and if so, shows
		   them in a tooltip. Technical commentaries (e.g. [%.*] are
		   ingored.
		 - Update board in comment editor with current position while
		   the comment editor is left open. (Joost t' Haart)
	* Allow suppression of Abort/Adjourn/Draw/Take back requests/offers (thanks to Jose Joao Morais)
	* Piece sets
	  - Bauhaus style piece set (thanks to Sandra Snan)
	  - Fix scaling issue in USCF set
	* Browse window
	  - Allow scaling by +/- keys and Ctrl-Mouse wheel
	  - Use mouse wheel to go through the game
	* Header searches
	  - Header searches with open trees now act as a filter, that is
	  they now restrict the games displayed in Best Games and Game
	  list. In other words if a header search was performed it's
	  results are no longer reset by the Tree searches. Tree statistics
	  however are still calculated for teh full database.  (Thanks to
	  Gerd Lorscheid)
	  - Annotators are now searchable (Thanks to Gerd Lorscheid)
	  - Easy way to search for all games that are annotated by either
	  NAGs, comments or variations. (Thanks to Gerd Lorscheid)
	* API Changes:
		- ::tooltip::UnSet to remove a tooltip + message
		- sc_filter clean: unset both db and tree filter
- Fixes :
	* Fixed a bug in exception handling of Novag Citrine connection
	* FICS console uses fixed font
	* allow Elo-rating corrections up to 2015
	* Correct move numbers in engine PV output in locked mode
	  (http://sourceforge.net/tracker/index.php?func=detail&aid=3001826&group_id=26963&atid=389080)
	* Limit the history list of FEN notation in board setup (thanks to Steve)
	* Remove some CE-engines not in the default distribution from Makefile.conf
	* HTML export
	    - Corrected display of player names (no {} pair around it)
	    - Move comments are rendered according css style
	* Duplicate games display did not highlight correctly
	* It was not possible to remove a tb directory
	* Allow for Phalanx XXIII as a version of Phalanx, as it includes all patches necessary for Scid
	* Crash when replacing a game in certain languages (Thanks to Milan Zamazal)
	* Annotation
	    - Inrush fix, mainly noticeable with batch annotation without using book
	    - Repair lockup with UCI engines that announce their bestmove before being stopped
	      when they see a forced mate (stockfish...)
	    - Repair lockup with UCI engines that refuse to start doing anything useful when they
	      are started in a mate position (stockfish...)
	    - Added "crushing" (+-- or --+) as potential score NAG
	    - More consistency in starting and stopping analysis
	* Header search with ignore colours: colours were obeyed for the results (thanks to Gerd Lohrscheid)
	* Allow suppression of Abort/Adjourn/Draw/Takeback requests on FICS (thanks to Jose Joao Morais)
	* Reorder piece sets alphabetically
	* Allow the informant value for "won game" to count up to "mate found" (= 327)
	* Tiny font can now be set from the GUI
	* Input engine parameters were not used properly (ID: 2969395)
	* Minor flaw in Scid.eco (ID: 2963067;  thanks to Daniel Karlsson)
	* Correction of possible overflow in material signature (ID: 2992119; thanks to Gregor Cramer)
	* Optimisations for tree search (Thanks to G. Lohrscheidt)
    * Comment editor text frame scales properly
	* Some directories did not get stored properly (epd, report)
	* Entering try mode no longer kills/hides comments in the game.
