Implemented state support as a mixin

Added html to each tab in the history example to make it clearer which tab is currently activated

Refactored the GridFilters plugin UX as
FiltersFeature, a Ext.grid.Feature subclass, and ported it to work with

match

grid filter, even if it is an already instantiated Filter rather than a
filter config object

Refactoring a Theming so it is easier to customize

Updated the themes example to include more components

Added HTTP error info to the data operation when a request fails

which a header may be configured with a nested headers config object as
well as a text/header string

The Ext 3.x class ActionColumn has been implemented in 4.x as ActionHeader

Cleaned all locale packages files

Introduced a new getAssociatedData method on Model to make it easier to aggregate model data

Added window state management

Implemented Ext.menu.DateMenu class

Implemented Ext.menu.ColorMenu class

Cleanup FocusManager's handling of component add/destroy when enabled

Convert TabBar to use FocusManager.subscribe instead of its own KeyNav

Grid Header needs to give visual
indication when it is focused, which will show the menu trigger. This
supports key navigation on grid headers and the ability to press down to
open the header menu. The menu needs the trigger to be shown since it
aligns itself to the trigger

Add deep copy operation to NodeInterface

Allow Ext.form.Basic#markInvalid to accept a Ext.data.Errors object

Added logic to reduce/increase the number of columns in the shadowCt to match the number of items if columns:'auto'

Make Ext.form.Field.resetOriginalValue update the field's dirty state to match

Automatically convert objects into records with NodeInterface

Make ComboBox.getValue return the raw
text field value if it does not match the display value from the last
list selection or setValue call. Allows submitting values that do not
appear in the store

Enhance the appendChild, removeChild,
insertBefore code on the NodeInterface with suppressEvents capabilities.
This optimizes the performance of the initial Tree rendering
drastically

Implemented Grid RowEditing

Basic.updateRecord() will now use the
actual field data for updating the Model fields rather than the
submit-friendly string equivalent of the form field data. Certain string
encodings are not compatible with Model field covert methods if they
are not in the exact/proper format, e.g. Date fields

Remove Canvas support as it is not ready for release. SVG/VML still covers all desktop platforms.

API Changes

Moved methods slated for deprecation to the compat layer

Added a new ElementLoader class that is
the superclass of ComponentLoader. The purpose of this class is to
replace Ext.Updater. Updater is removed and the load method now points
to the new loader

Move model creation into the model itself, essentially deprecates regModel

Time axis now works with Dates and not formatted strings

Move Ext.util.Date methods over to Ext.Date. Changed all references to Ext.Date in code, examples and tests

Add workaround to
Ext.core.Element#getWidth to avoid Gecko bug where it returns an
offsetWidth that rounds down the actual width due to subpixel font rendering
. This logic was previously in a couple of components, this commit moves that up to Element.getWidth

Fix AbstractPanel.bodyCls to also support array values

Created an AbstractMixedCollection which MixedCollection extends from

Sortable refactored as a mixin

Refactored Sorting on MixedCollection, TreeStore, and TreePanel to use the new Sortable mixin

Absolute Layout will now always use setItemSize even if an anchor property isn't specified

Ensure the page parameter gets sent on remote data loading

Remove any trace of applyTo throughout the framework

Updating the BoundList selection on setValue for ComboBox is now the default behavior

Selection models are now consistent:
Moved grid/CellSelectionModel.js to selection/CellModel.js,
grid/RowSelectionModel.js to selection/RowModel.js, and
grid/CheckBoxSelectionModel to selection/CheckBoxModel.js. Namespace
moved to Ext.selection as well

Set AjaxProxy as the default proxy

Normalize store aliases to be
store.name. Added the ability to specify a store configuration when
creating a data bound class. Note that this requires all of the stores
to be looked up using StoreMgr.lookup so that we can determine whether
we have received an id, a config or an instance

Enhance DataView UI event handling

Remove dependency of CellEditing on CellSelectionModel

Compatibility Changes

Implemented compat layer for PagingToolbar and MemoryProxy

Significant update to AbstractStore compat layer to handle different store/proxy/reader config setups
