[EXTJSIV-434] Prevent IE6-7 from giving focus to the HtmlEditor iframe when setting its contentEditable=true

[EXTJSIV-449] TableView should not steal
the focus when a header is resized. The header layouts occurred when a
scrollbar was being added and removed by the TablePanel, causing any
previously focused item to lose focus, with focusing going to the
TableView. So, a "search filter text box", for example, would lose focus
at random points

[EXTJSIV-569] Fix bug with nodes being inserted in the wrong location in the NodeStore

[EXTJSIV-607] Fix z-index of border floated region

[EXTJSIV-372] Fix an issue with flickering when using cell editing in FF on Linux

[EXTJSIV-608] Fix issue when creating records at a remote source

[EXTJSIV-450] FocusManager will only add
tabIndex to DOM nodes that really need them for programmatic focusing.
This will ensure default tabIndicies will remain in tact

[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-560] Remove focused cls on items in a TableView when deselecting them

[EXTJSIV-614] Prevent combobox dropdown from getting closed before the selectOnTab handler has a chance to fire in WebKit

[EXTJSIV-622] When IE9 positions an
element offscreen via offsets, the offsetWidth is inaccurately reported.
For IE9 only, we render on screen before removing. Fixes an issue with
Ext.getScrollBarWidth

[EXTJSIV-439] Changed images for the DataView examples to gif for IE6

[EXTJSIV-615] Fix an issue when using an idProperty other than "id"

RowEditor will handle resize, move, show, and hide of columns properly before the editor is brought up for the first time

[EXTJSIV-480] Table layout: added work
around for a bug in Opera 10.5 where it makes table cells wider than
they should be if their child element has border-box sizing and
horizontal padding

[EXTJSIV-641] Fix an issue with creating items into a local storage object

[EXTJSIV-440][EXTJSIV-633] Fix Ext.ux.AnimatedDataView cross-browser issue

CellEditing will complete an edit before
grabbing critical information about the next edit, since the view is
refreshed upon edit completion

[EXTJSIV-371] CellEditing and CellModel
will continue cell editing on tabs even across cells with no editor, and
stop when the editing ends via a non-tab exit point such as blurring
the field

[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

[EXTJSIV-401][EXTJSIV-496] Rework
active/inactive tab styling to be consistent across all browsers and
avoid the floating border strip

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

Set up compat code for TreePanel, AsyncTreeNode, TreeLoader and TreeSorter

Moved deprecated TreePanel members to the compat file

Known Issues / Upcoming Changes

MVC Example applications and guide

Collapsed vertical headers need to be restyled in IE

Toolips in IE8 have too much padding on the header which can cause it to clip text

Tab Scroller is not working properly in FF < 4

Deprecated (methods slated for
deprecation) and Since (what version methods were introduced)
implemented within the documentation

Column Layout has some performance issues which will be addressed in the next release

API naming consistency implementation

Field Layout performance has improved, but is not where it should be for IE

IE9 Strict mode subpixel rounding can cause wrapping issues (similar to https://bugzilla.mozilla.org/show_bug.cgi?id=458617)
