# Release Notes for Ext JS 4 Beta 3

Release Notes: April 14, 2011
Version Number: 4.0.0beta3

## New In This Release

  - MVC Feed Viewer
  - MVC Nested Data
  - Lazy Loading Data Associations
  - Property Grid
  - HTML Table to ExtJS Grid

- Bug Fixes
  - [EXTJSIV-664][EXTJSIV-645] Fix Organizer and GroupTabs examples
  - Header icon and vertical title text should no longer be focusable
  - [EXTJSIV-550] Fix Column layout to accurately arrange columns, taking scrollbars into account
  - Fixed inheritableStatics for full inheritance tree
  - Removed focus line from buttons in IE
  - [EXTJSIV-177] Fixed disabled toolbar buttons
  - [EXTJSIV-676] Removed icon cls's from buttons in themes examples
  - Add additional CSS class when border is set to false for the HeaderContainer
  - [EXTJSIV-650] Fix double border issue with tree items

  - [EXTJSIV-688] Fixed focus issue with datepicker
  - [EXTJSIV-683] Fixed collapsed vertical panel header image
  - [EXTJSIV-678] Fixed css issue with the history example
  - [EXTJSIV-603] Work around the brutal IE9 Strict mode subpixel rounding bug which can cause wrapping issues (similar to https://bugzilla.mozilla.org/show_bug.cgi?id=458617)
  - [EXTJSIV-700] XTemplate should now handle dot (.) syntax for date objects as well. Since a date will yield a typeof of "object", we can't distinguish it from other "object" types; so we use the object prototype toString, in Ext.isDate
  - [EXTJSIV-671] TablePanel will not stop the mousewheel browser event when its reached the end of the scroll height/width. Also, the grid will only scroll when scrolling above the scroller and the view (not the headers, panel header, etc.)
  - [EXTJSIV-677] Editor shouldn't be hiding/showing its field, merely itself. This fixes positioning issues as well as the editor being still visible and floating over content, making it impossible to click to the things underneath of it
  - [EXTJSIV-702] RowEditor should vertically align itself to a row based on its y offset to its top-most static parent, not just its immediate parent (table)
  - [EXTJSIV-704] Prevent duplicate tabchange events from firing
  - [EXTJSIV-705] Fix problem with Shadow class calculations

  - [EXTJSIV-689] Fix bug in OS X where grid/tree scrollers would stop responding.
  - [EXTJSIV-648][EXTJSIV-684] Auto-width fields must set the width of their outer element to match the total width of their internal contents, to prevent wrapping of the pieces during layout operations which would cause calculated heights to be too tall. Re-added the getBodyNaturalWidth method to support this, and changed the implementations where possible to avoid querying element sizes for optimum speed
  - [EXTJSIV-709] Grid row height will be preserved even if the row is empty
  - [EXTJSIV-804] Fix cycle button initial positioning in example
  - [EXTJSIV-710] Fix ItemSelector button behaviours
  - [EXTJSIV-797] Handle forceSelection in multiSelect ComboBoxes

  - [EXTJSIV-817] Fix TablePanel applyState to not setWidth on an unrendered component
  - [EXTJSIV-192] Allow button layout to run when its text has changed; this allows min/maxWidth to be applied based on the new text length

  - [EXTJSIV-809] Add Ext.ns() to the Ext.direct remoting echo
  - [EXTJSIV-828] Fix issue when dragging/dropping onto the same grid
  - [EXTJSIV-841] Fix duplicate method name in plugin
  - [EXTJSIV-842] When show is called on the tab, set it to active. Also ensure listeners are cleaned up when the tab is removed
  - [EXTJSIV-850] Fix issue when using treenode with leaf: false and children

  - [EXTJSIV-879] Move sync to be the last operation for add/remove methods on the store
  - [EXTJSIV-640] Ensure we keep track of the number of fields in the reader. Since the tree decorates the model, it can cause problems when running the extractor functions

  - [EXTJSIV-577] Fix up styling to prevent unneeded scrollbar
  - [EXTJSIV-234] Fix up margins on DatView example

  - [EXTJSIV-589] CellEditing now fires beforeedit, validateedit and afteredit appropriately
  - [EXTJSIV-610] CellModel will now call its base Model's doSelect and doDeselect functions so it is maintaining the selected record along with the selected position (row/column)
  - [EXTJSIV-418] CheckColumn now will handle the Enter/Space keys for toggling its select state
  - [EXTJSIV-609] CellModel fires its select/deselect events now

  - [EXTJSIV-606] Constrained Windows no longer lose their center positioning
  - [EXTJSIV-508] Give a visual indication of a selected/focused tree node in the check-tree example
  - [EXTJSIV-508] Tree selection model handles enter/space to check any checkbox tree nodes
  - [EXTJSIV-663] Ensure ServerProxy checks if the value is defined as opposed to just truthy
  - [EXTJSIV-593] Numeric axis is now aware of chart substores, that way it can update when grouping/ungrouping time axis

- Enhancements
  - [EXTJSIV-73] Optimized class system performance - round 1
  - Added a simple Gauge Chart
  - Add Ext.Array.sort which is a guaranteed stable sort
  - [EXTJSIV-556] Implement a buffered grid example loading thousands records and buffering the rendering. Required minor changes to PagingScroller, BufferStore and related classes
  - [EXTJSIV-193] Put iconCls and tools into ghosted windows
  - [EXTJSIV-471] RowEditing will now scroll the buttons into view when they are out of sight due to being near the bottom. Also will enforce row selection and keeping a row in view when starting an edit for smoother animations
  - [EXTJSIV-426] Remove redundant validation for allowBlank in Ext.form.Text
  - [EXTJSIV-427] Date and Time would always return null from getValue if the raw value could not be parsed as a date; this was resulting in such values being treated as valid during validation and not being seen as dirty. Changed so that getValue will return the raw value if it cannot be parsed. Also added logic to attempt parsing of the 'value' config during init so that originalValue is a valid Date object for dirty comparison
  - [EXTJSIV-448] Implement readOnly and setReadOnly for Checkbox and Radio fields
  - [EXTJSIV-416] Give fields within fieldset an anchor so they get a width in IE6
  - [EXTJSIV-530] Added port number support to localhost detection
  - Add required classes to Chart LiveUpdate example
  - Increase LiveSearchGridPanel reactiveness
  - [EXTJSIV-529] Element.getColor() will properly accept an empty string as a prefix, which is needed for color animations
  - [EXTJSIV-529] Enable afterRepair fx on dd.DragZone and TreeViewDragZone
  - [EXTJSIV-38] TreeViewDropZone will now highlight successfully dropped nodes
  - [EXTJSIV-38] Use the selectedItemCls setting on TableView prototype to handle the quick remove/add of that cls when highlighting a repair
  - [EXTJSIV-38] TreeViewDragZone will highlight all records that were dragged, for the case of multiselect tree sel model
  - [EXTJSIV-185] Removed .png slicer images + changing to gif (we <3 IE6)
  - [EXTJSIV-346] adding gif versions of icons for treegrid example
  - [EXTJSIV-475] LoadMask may now be configured with a Component to mask as an alternative to just an element. If configured with a Component, it masks the Component's contentTarget. If the Component changes size during loading, the mask's message is recentered. DataView configures its LoadMask by passing itself if it is standalone, or its owning Container if it is inside a Container
  - [EXTJSIV-478] Added the empty cls to all browsers, not just browsers that do not support `placeholder`. this is because of a styling issue in webkit
  - [EXTJSIV-540] Button over when disabled will not apply the hover background linear gradient anymore. disabled classes now get cascaded priority over background-image
  - [EXTJSIV-457] The DragZone was triggering a selection change on mousedown, which was resulting in duplicate selection calls when the DataView was configured to select on click. Moved the former from the mousedown handler to the start of the drag to avoid duplicate selection
  - Improved some Loader's alias functions for performance
  - [EXTJSIV-258][EXTJSIV-259]Refactor Shadow for floating Components
  - [EXTJSIV-551] Menu should not fire click, mouseover, or mouseleave events when its disabled. Menu items will not get any interaction when the menu is disabled
  - Menu will only activate items that can be activated, however, always deactivate the active item when applicable
  - [EXTJSIV-502] Add comment in HtmlEditor explaining how forcing documentMode in the Web Developer Tools will override the mode used by the iframe, causing scrollbars in IE8
  - [EXTJSIV-543] Horizontal scrolling does not rely on having records within the body of the grid. It is calculated off of the headercontainer instead
  - [EXTJSIV-547] Added in browser check for Opera for Mousewheel. Found additional information about Opera and its' mousewheel implementation here: http://www.switchonthecode.com/tutorials/javascript-tutorial-the-scroll-wheel To quote the important parts... "The weirdness comes in because IE and Firefox have very different names for the scroll event. In Internet Explorer, the event is called onmousewheel, while in Firefox the event is called DOMMouseScroll. To make it even worse, Opera uses the Internet Explorer event name (without the 'on' part, so just mousewheel), but Opera needs to use the Firefox way of attaching event listeners."
  - [EXTJSIV-564] Implement index support in selectRange rather than requiring the developer to pass a record instance
  - Updated grid row selection stuff to support IE better
  - [EXTJSIV-447] Add fieldStyle config and setFieldStyle method to Ext.form.BaseField, to allow direct manipulation of the inputEl CSS style
  - Legacy code in the widgets directory removed
  - RowEditor offsets itself by using bottom instead of top, in case of tall rows
  - [EXTJSIV-567] Table State implementation now restores width and visibility
  - [EXTJSIV-532] Add tooltip support on Radar series
  - [EXTJSIV-559][EXTJSIV-373]Provide accurate repair position for Header Drag Zones
  - [EXTJSIV-358] HeaderContainer will disable checkbox in column menu when there is only a single header
  - [EXTJSIV-582] Add Ext.Error custom error reporting class
  - [EXTJSIV-574] Add an alias for all series and handle custom series creation and adding them in an imperative way
  - [EXTJSIV-514] Reimplement rendering of Checkbox and Radio to use a custom image rather than native controls, for greater styling control and consistency across browsers
  - [EXTJSIV-241] Lots of cleanup on Component destroy method
  - [EXTJSIV-599] Make node loaded a field in NodeInterface. When appending a child to a node, mark it as loaded
  - Add the ability to pass a url to the load method on a Store with a ServerProxy defined on it
  - [EXTJSIV-394] Added itemTpl support for DataView
  - Add method to allow destroying the field layout's singleton QuickTip instance
  - [EXTJSIV-604] Allow height to be set on text fields
  - The footer toolbar's (fbar/buttons cfg) spacer shouldn't be focusable anymore
  - Button now has a visual state when focused, which currently mirrors the mouseover state. Also removed a focus/blur method in Button that was unnecessary
  - [EXTJSIV-450] FormPanel will provide default tab stops for its fields and buttons, so that all fields are tabbed through first, and then buttons second
  - [EXTJSIV-450] AbstractPanel and AbstractDock will return/render docked items in their visual representative order, respectively. Docked items have a default weighting, so that they are returned/rendered in (t,l,r,b) order. In the case of a Dock layout, the top/left items are rendered before any existing DOM nodes in the render target (body el, in the case of a Panel), and right/bottom items are rendered after the existing DOM nodes. This keeps our DOM nodes in order of their visual representation to support tab stops, ARIA readers, etc. Also, getDockedItems/getRefItems of AbstractPanel will return the same type of ordering by default to support logical ordering of ComponentQuery's and FocusManager navigation
  - Move FocusManager's tabIndex whitelist to the prototype so it's not defined over and over again for each call to setFocus
  - [EXTJSIV-418] Added keydown event handling to DataView
  - [EXTJSIV-600] Allow form fields to display all errors returned from getErrors at once, rather than only displaying the first
  - [EXTJSIV-304] Grid reconfigure method implemented
  - [EXTJSIV-498] Changed DataView to store the internal record IDs on the view DOM nodes for lookup by record and vice versa. This matters since blockRefresh's can happen and the store becomes out of sync with the DOM nodes, such as was the case with the Animated DataView plugin
  - [EXTJSIV-483] Implement expanded cls for rows inside collectData instead of getRowClass. This allows the user to override getRowClass without them having to worry about expanded state
  - [EXTJSIV-628] Added remove and destroy methods in Sprite.
  - [EXTJSIV-55] Add boxLabelAlign config to allow the user to place the boxLabel before or after the checkbox/radio
  - [EXTJSIV-517] Optimized buffering of requests in PagingScroller
  - [EXTJSIV-596] border:false on a Window removes borders from the body. The Window itself remains framed
  - [EXTJSIV-523] Use the verticalScrollers calculated height when available rather than the raw dom
  - [EXTJSIV-315] Updated access theme to have better styling across all components
  - [EXTJSIV-613] Move extraParams onto the object instead of being per request
  - RowEditor now transitions the error summary tip properly on back-to-back invalid records
  - Remove the inline unselectable cls, and instead call unselectable() on the table view's el after it's been rendered. This fixes a selection problem in Chrome when double clicking in a grid
  - [EXTJSIV-527] Add a workaround for the WebKit MarginRight bug with Anchor Layouts to make them much faster
  - [EXTJSIV-527] Componentlayout.afterLayout will now only be called when a ComponentLayout occurs
  - [EXTJSIV-527] Ensure Card.setActiveItem calls onLayout properly
  - Moved all locking behavior out of the LockingGridPanel subclass
  - [EXTJSIV-660] Add startDay to Date Field
  - [EXTJSIV-653] Added DirectStore shortcut
- API Changes
  - [EXTJSIV-276] The "headers" config in GridPanel has been renamed to the 3.x compatible "columns". All supporting classes are now named XxxxxColumn and are in the Ext.grid.column package. Column xtypes are the same as they were in 3.x
  - [EXTJSIV-562] Added hideEmptyLabel config which automatically collapses the label space when fieldLabel is empty. Made this the default behavior everywhere; this is a slight change from the old form layout which defaulted to maintaining the space unless hideLabel=false
  - [EXTJSIV-59] Rename some methods in Menu to be consistent with framework standards
  - Modified field layout to avoid setting styles when not needed. The fieldLabel element's styles are now applied during render in the template and not in the layout. Fields whose size are not managed by a container no longer set their internal element sizes during layout this can result in wrapping since fields are floated
  - Add inverse iteration support to Ext.Array.each
  - Rename hlColor to repairHighlightColor for Tree DragSource
  - [EXTJSIV-38] TreeViewDDPlugin now has "nodeHighlightColor" which is used on repairs and drops, if applicable. Passing it as the "repairHighlightColor" to the drag zone in this commit. Will be passed to drop zone as "dropHighlightColor"
  - [EXTJSIV-38] Renamed hlDrop to nodeHighlightOnDrop and nodeHighlightOnRepair on the TreeViewDDPlugin class. They are routed to the TreeViewDragZone and TreeViewDropZone as repairHighlight and dropHighlight respectively
  - [EXTJSIV-552] Rename MessageBoxWindow to MessageBox
  - Move all locales package from core to extjs
  - [EXTJSIV-548] Add allowDrag config option on NodeInterface. Set it to false by default for root nodes
  - [EXTJSIV-549] Change the names for the relayed events from TreeStore to TreePanel so that they don't collide with Panel's events
  - [EXTJSIV-602] Put GridViewDDPlugin and TreeViewDDPlugin into proper namespaces (Ext.grid.plugin)
  - [EXTJSIV-269] Renamed enableCacheBuster to disableCaching, added disableCachingParam config
  - [EXTJSIV-581] Fixed up the API for TreeStore, TreeView and TreePanel. Also fixed some bugs related to changing the root node dynamically, loading data after TreePanel has already been created and expanding a node while its loading
  - [EXTJSIV-598] We no longer use the global QuickTips singleton for form error tips. We now create a QuickTip singleton just for the field layout, with the proper baseCls for framing, and register it to respond to an 'errorqtip' property
  - [EXTJSIV-534] Refactor Lockable into mixin
  - AbstractSummaryFeature, ChunkingFeature, GroupingFeature, RowSummaryFeature, RowBodyFeature, RowWrapFeature, and SummaryFeature moved to the Ext.grid.feature namespace
  - Rename locked from Header/Column to ddLock so that it doesnt conflict with the new locking functionality
- Compatibility Changes
  - Removed compat reversing of El.down/El.child - There are too many places in Ext itself that use these calls, and reversing them in the compat layer to match 3.x behavior breaks some Ext 4 code. This will have to remain a documented breaking change in the migration guide

  - Fix up allowEl option for within, it should be used as a fallback if the element isn't contained within the parent
  - Fix a highlighting issues with Pie
  - Correct use of "float" keyword as object property name
  - Fix buttons with noLinearGradients
  - Change how field layout handles horizontal sizing when no set width is specified It now uses the shrink-wrapped natural size of its body content plus label, rather than the width of the outermost element. This fixes layout issues when fields are used as hbox items, since the outer element has zero width during initial layout. It also prevents fields from expanding to the full width of their container by default, which is more consistent with the Ext3 behavior
  - Fix Box layout for when margins are specified in object for, but without all 4 properties. Default to zero
  - Remove extraneous quote in GroupingFeature template
  - Fix an issue when using autoHide and delegate with ToolTip
  - Fix Combo hiding when using the scroller in FireFox
  - Fix specificity of .x-form-invalid-field selector for textareas so the proper styling is shown
  - Fixed width of slider tips, and tips in general, in IE quirks mode. Switches tips to use the table framing so they don't expand to full viewport width. Removes the bad width-setting logic from Ext.slider.Tip so it is properly handled by the layout class
  - Fix box layout to correctly calculate middle alignment
  - Correctly autosize the innerCt according to max component size (now takes innerCt's borders into account)
  - Fix an issue when using a defaultValue with Boolean fields
  - Fix an issue when saving/loading a model and the request fails

  - Fix an issue where Model.setProxy would not accept a Proxy instance
  - Fix a problem in the ZIndexManager where if a modal Window showed another floating Component (such as the BoundList of a Picker Field), the modal mask is hidden during the period that the Window is not at the topmost position in the z-index stack. Now the modal mask is only hidden when there are no Modal floating Components (usually modal Windows) displayed
  - Fixed some IE 6/7/8 styles in Menu. IE6 had a "slit" in the item separator that is no longer there. Browsers without linear gradient support now use a nice looking background image for active items
  - Fix for Menu in Opera 10, which does not report an element's width if it is not a part of a render box. We have to temporarily add it to the body to perform a measurement
  - Change ReloadChart example to bind to the correct (left) axis

  - Introduced a TreePanel capable of supporting multiple headers. Abstracted shared logic between the Tree and Grid into a TablePanel class.
  - Tab overflow implemented
  - Menu overflow implemented
  - Drag and Drop for Dataviews implemented
  - Implemented Tree and Grid drag and drop
  - FocusManager implemented (Jarred ELABORATE)
  - HTMLEditor implemented
  - Ext Direct implemented, with a new DirectProxy
  - Add support to ComponentQuery to accept member expression selectors in pseudo-class selectors
  - Support member expression selectors for ComponentQuery in the same way as attribute selectors, by allowing them to occur anywhere within a single selector chain to further filter the working group of items
  - Added inheritable statics for Classes
  - Refactor cleanup for Scatter Series
  - Ensure doLayout doesn't run a layout that is already in progress
  - Implement pruneRemoved for Ext.selection.Model
  - Ensure selection model is refreshed when DataView is refreshed or records are added
  - Create a reference to the Ext sandbox instance in generated functions
  - Increment snap ends `to` argument properly
  - Add feed viewer icon
  - Box layout. Correct allocation of spare space to non-flexed items after a shortfall has caused a reduction to minSize
  - Button layout: Now sets the outer element width if a numeric width passed
  - Added "focusable: false" to menu & toolbar separators so they are not candidates for gaining focus
  - Updated Ext.menu.* to play nicely with Ext.FocusManager when enabled
  - Menu: Constrain to within browser viewport and use box layout scroll overflow handler
  - Implement disabled style for horizontal scroller
  - Implement Ext.selection.TreeModel handling for left/right in the flattreeview. Turn it on in the TreePanel
  - Enforce that user clicks expander to toggle a record
  - Ensure that collapsed region placeholders are z-indexed above slide-ins
  - Border layout now honors the floatable: false config
  - Menus no longer access elements that are not rendered
  - MenuManager now uses Ext.Array.remove instead of calling remove on the Array instance
  - Ensure a region isn't floated if floatable: false is specified.
  - DataView now ensures the selections get refreshed when the view does
  - Implemented button as a link when an href/url is configured
  - Implementes initial collapse state to collapse when the outermost Container (usually a Viewport) has been layed out, or, if no Container, on first component layout
  - Removed legacy images file
  - The framing method for non-CSS3 browsers which uses a table is necessary for proper width of floated components in IE quirks mode. Some floated components, such as Tip, have Dock layout which requires being able to insert docked items directly into the outermost element; this was failing when the outermost element was the table element. Changed to have a div as the outermost element with the table as an immediate child
  - Prevent validation when initializing the field value, rather than validating but then clearing errors
  - Apply correct CSS classes to Panel headers within collapsed Panels so that bordering can be kept consistent
  - Add rule for column layout child items. They must float:left
  - Implement 3.x style Column layout where child items float across the Container (Note this API is not finalized and may change)
  - Labels for vertical axis are now hidden when they're too close to each other (or overlapping)
  - Implemented weighting on docked items by returning a sorted array based on a weight property in AbstractPanel's getDockedItems method. Default weight is 0
  - Addition code to ensure the data proxy gets its params correctly
  - A parent menu's hide timer (on mouse leave) will be cancelled when hovering over a submenu
  - Add x-quirks to when we're in quirks mode (!Ext.isStrict), useful for CSS that must know whether or not in quirks mode, as x-border-box is applied on all browsers that aren't IE6/7 in both quirks and strict modes
  - Implemented hideHeaders and provide backwards compat layer for preventHeaders
  - Implement fill:false in Accordion layout which means that expanded child Panels are not fitted within the accordion Container, but assume their natural height. Implement multi:true which allows multiple items to be opened at once when using fill:true. The opened Panels share available space by using the Box layout flex config
  - Implement a Component click event in Header. This is for use by Panel's titleCollapse configuration
  - Accordion layout now propagates its Panel-specific configurations to child Panels
  - Implement titleCollapse for Panel
  - Added writeAllFields method to the data writers
  - Add beforeselect event to DataViewModel
  - Restored original fonts and font-weights in the default theme to be the same as of 3.3
  - Class.override now adds an owner reference to methods that didn't exist in the superclass yet
  - Users can now override the sortParam used when sorting a particular Header
  - Ensure we use the browser normalized array methods for DataView
  - Add a findLayoutController method which goes up the ownerCt chain to find the highest currently active layout so that afterlayout events may be tracked to fire when a final size has been arrived at
  - Card layout now calls afterLayout on the card Container after card activation
  - Refactor getWidth, getHeight, and getViewSize to account for IE quirks mode measurement issues when a container is overflowed
  - TabBar now scrolls the active tab into view upon set of active tab
  - Added new isIEQuirks flag
  - Tweak bar/column chart starting points so they don't overlap the axis
  - Ensure box layout takes border space of the innerCt into account when centering
  - Tooltips no longer get focus when they call toFront()
  - Users may now provide their own CSS rules for enabling overflow on other box layout Containers. Currently we support Menu, Toolbar and TabBar overflowing.
  - Window will now force the header creation if draggable is set to true
  - Added a new Body Component layout for Components which maintain an inner body element which must synchronize its size with the encapsulating element
  - FieldSet now uses a Component layout to synchronize the size of its body element with the size available within its main, encapsulating element
  - Due to the use of the descendant selector for setting float/etc on field labels, fields nested within a FieldContainer would always get the styles corresponding to the container's labelAlign, even if their own labelAlign was different. Changed it so the label alignment className is now given directly to the label element rather than the parent, so the CSS no longer has to use descendant selectors
  - The Trigger component layout was setting the height of the input field based on the incoming requested height; single-line input fields should always get their height from the CSS and ignore the layout's height
  - Made AbstractDataView less strict in the type of parameter it accepts as a target for getRecord. It may now be an HtmlElement or an Ext.Element
  - Added a frameHeader config which turns on/off framing on the Panel Header
  - Added a ComponentLayout for Editor
  - Ensure formBind is updated when the form is first created & when items are added/removed
  - Added the ability to assign a custom reader for reading associations
- API Changes
  - Added destroy method to Model
  - Move getItemForPoint up to Series and implement isItemInPoint in each series
  - Added static methods for DataView
  - Containers calls to doLayout will call ComponentLayout instead of ContainerLayout when they don't have dimensions (autosized)
  - Change ComponentQuery's member expression filter function to use an "items" argument rather then accessing arguments.callee.caller.arguments, to be ES5/strict compliant and more straightforward
  - Remove the use of arguments.callee from EventManager.createListenerWrap, and instead give a named reference to the return function. ES5/strict compliant, and works in all browsers
  - Ensure DataView uses getItemSelector() when firing events
  - Changed $prefix in scss to include `x-` not just `x`
  - Remove box scroller subclasses. There's only one now which handles perpendicular/parallel
  - Box layouts: new properties for use by box layout overflow handlers
  - All box layout overflow scrolling is handled by a single class: Scroller
  - TabBar now removes header text item and tool spacer. Use scroller overflow handler
  - Added a new preventDefault option to button
  - Remove HorizontalMenu class. There is only one Menu overflow handler
  - Move scroll-specific methods out of overflow handler base class into the Scroll handler
  - Added extra menu-active cls with btn.ui into menuShow
  - Added menu-active cls to css
  - Add slider layout class as dependency
  - Not all floating components should be automatically focused when they are brought to the front; this adds a focusOnToFront config to control that behavior on a class or instance basis. Defaults to true, but is overridden to false in Tip and in the BoundList instances created by ComboBox and Time fields, to prevent losing field focus
  - Ext.grid.View renamed to Ext.view.Table
  - Throw an error message when trying to bind to an event handler that doesn't exist
  - Add a border to collapsed panel headers depending on their docked position
  - Renamed the legacySortMode config to simpleSortMode
  - Added new API config for Server proxy and subclasses
  - Removed Class.extend method (not to be confused with Ext.extend)
  - Removed unused getHead method from Ext.data
  - Ext.Date.parseDate changed to Ext.Date.parse. Add deprecaton for the older parseDate API.

  - Changed "operation-complete" event in Batch to "operationcomplete"
- Compatibility Changes
  - Added Ext.lib.Ajax compat
  - Added Ext.reg / ComponentManager.regiserType aliases
  - Fixed editor example's Panel.header reference
  - Include css for message box example
  - Alias Ext.lib.Dom.* to Element
  - Fixed registerType/reg aliases, added registerPlugin/preg

  - Moved Component overrides from core-compat to compat
  - Added console msg about setting showErrors flag
  - Compat fix for loading stores with an inline data object
  - Moved xtype aliases from core-compat to compat
  - Added additional non-Core JS object prototype aliases
  - Ext.Date compat overrides
  - Additional msg for instance methods becoming statics
  - Added Ext.extend to the compat file, fixed a null error if members arg is not passed
  - Added Store.setDefaultSort compat override
  - Added GridPanel and Model compat overrides
  - Added applyTo message to Ext.Component
  - Added Ext.Compat.breaking() to show breaking changes
  - Added appropriate messaging for most of the compat configs
  - Moved compat items from combobox into the compat file
  - Renamed Ext.Base.extend -> Ext.Base.addStatics, deprecated Ext.Base.implement for Ext.Base.extend. In short, from now on, use MyClass.addStatics for statics members, MyClass.extend for prototype members
  - Fixed tpl alias to implement the getInnerTpl method correctly
  - Added isDef checks where needed to log messages only for defined configs

  - Button layout caches measured styles for efficiency
  - Feed Viewer uses CycleButton to cycle through the preview pane options
  - Bringing a floating Component (such as a Window) to the front of its ZIndex stack now focuses it on a 10ms delay. Focusing several Windows in succession results in only the last Window actually receiving focus
  - Refactor Border layout to use new Element effects methods to slide regions in and out

  - Changed tabs to use the base-color and not hard coded colors
  - Changed button to no longer use hardcoded variables
  - Make TabPanel dock the TabBar according to the tabPosition config
  - SVG text is now unselectable
  - A new 'errorchange' event has been added to Ext.form.Labelable, fired whenever set/unsetActiveError is called. This is similar to the 'validitychange' event on Ext.form.Field but is fired by Labelable components which are not Fields, such as FieldContainer. It also fires when the validity is staying invalid but the message changes, which is more useful in some cases
  - BaseField now adds a .x-form-field-invalid class to the inputEl, and this is used in the CSS rather than using the outer .x-form-invalid and a descendant selector; this allows proper styling of child fields of a FieldContainer when the container has an error message displayed
  - ComboBox clearValue method added back in
  - Toolbar now uses the base-color
  - Add extra checks to figure out whether we need to do DST parsing or not for Date function
  - Add triggerNCls-over and triggerNCls-click classes to individual trigger buttons, so each one can be given interaction styling independently rather than requiring compound class selectors. Fixes spinner button states in IE
  - FeedViewer example: Button icon CSS rules should only override the background image. Otherwise Ext-specific styling rules will not apply
  - Group class attached to the icon element for style targeting in CheckItem
  - ComponentQuery can now accept back-to-back pseudo-class selectors, like :not():not():custom
  - Move back to setInterval instead of setTimer as a base for animation timing.
  - Allow for binding of multiple axes to a series via an array
- API Changes
  - AbstractLayout removed, Layout remains the base class now all AbstractLayout dependencies to Layout
  - AbstractDataView has new getter method getItemSelector
  - afteranimate event now fired as the last operation of the Anim.end method (instead of the beginning of the end)
  - layoutItem moved to ContainerLayout from Layout
  - Move resizeHandles config out of Window to Component
  - Box will no longer use CSS margins. It reads CSS margins and adds them to the configured margins, and clears CSS margins. This allows for more accurate positioning
  - Ext.form.CompositeField has been deprecated, as FieldContainer is now at feature parity. Alias has been added to compat file
  - Ext.form.Field#checkValidityChange has been removed, its logic has been moved into the validate method so it gets run when validate is called directly
  - Chart zoom functionality being changed to zoom the appropriate portions of the chart instead of everything

## API Changes

- All top level CSS classes are now prefixed with 'x-' by default instead of 'ext-' and can now be scoped. This is now consistent with all other Ext CSS classes.
- HashMap.add may now take a single argument similar to MixedCollection.add
- Animate methods (animate, stopAnimation, syncFx, sequenceFx, and getActiveAnimation) now applied via a mixin to Element/CompositeElement/Component/Sprite/SpriteGroup
- Keyframed animations (Animator.js) now fully support the iterations property
- Normalized API differences between Element's addCls and removeCls. Both now allow space separated strings
- Implement endDrag method in DragTracker
- Button now has a overMenuTrigger flag
- Rename pressClass to pressedCls and add check before cls removal in ClickRepeater
- Remove unecessary onDisable/onEnable override in menu.Item and Button
- Rename disabledClass to disableCls in Component
- Removed the positionAnimation property since it is no longer necessary with the Component.animate API
- Removed reverse parameter from keyframed animations
- The pause and running flags now maintained within keyframed animations (Animator.js)
- Update the RowSelectionModel constructor so we can add more useful contextual information to the event
- Menu now extends Panel to support docking

- Grid HeaderContainer dragging property now defaults to false
- Animate's getActiveAnimation will now return the current fx.Anim object if there is one or return false if none are active
- Renamed tab reorderer plugin to TabReorderer
- Renamed MenuManager to MenuManager
- Remove Ext.isForcedBorderBox property
- Remove the experimental enableForcedBoxModel property
- Ext.isBorderBox logic now reflects the use of css box model
- CheckboxGroup/RadioGroup setValue method has been simplified; it now only accepts a single format of an object of name-value mappings. The old additional formats will be added to the legacy compatibility layer as an override
- CheckboxGroup/RadioGroup getValue method has been changed to return an object of similar format to what is accepted by setValue for internal consistency. The old behavior has been moved to a new getChecked() method
- The methods setRawValue, getRawValue, valueToRaw, and rawToValue have been moved out of Field and into BaseField; this is to make the main Field interface simpler and more easily implemented on components which do not have the concept of an underlying "raw value" like CheckboxGroup
- Field now has a isEqual method which compares values returned from getValue() for logical equality, and is used anywhere a comparison is necessary such as checkChange() and isDirty(). The base implementation is a simple string comparison, but can be overridden by fields with more complex values
- Field now has a resetOriginalValue method which is called by the form when trackResetOnLoad=true instead of setting originalValue directly, this allows the behavior to be overridden by field subclasses
- Field's getSubmitValue method has been changed to a more powerful getSubmitData method, which returns a mapping object of name-value pairs; this allows single fields to return multiple values under different names rather than being limited to a single name per field. The getSubmitValue method has been retained as a helper but moved down to BaseField
- Introduced a batchChanges method on field as a utility for preventing excessive firing of change events in fields such as CheckboxGroup that have many sub-fields who may be updated as a batch
- Basic's isValid method has been changed back to its old behavior where it iterates through all fields in the form and triggers error markings. A new hasInvalidField method has been added to retain the more efficient short-circuited validity checking and preventing error markings

## Known Issues

- Tab heights not consistent across all browsers

Version Number: 4.0.0pr1

## New In This Release
