+This will be the last release to include binaries for Python 2.7. The

+some time, but no effort will be put into keeping it that way.

 New and improved in this release:
 
-* Add wx.Font.AddPrivateFont example to the demo.
+* Add a sample for wx.Font.AddPrivateFont to the demo.
 
 * Added wrappers for the OSXEnableAutomaticQuoteSubstitution,
-  OSXEnableAutomaticDashSubstitution, and OSXDisableAllSmartSubstitutions
-  methods in wx.TextCtrl. Also added OSXEnableAutomaticTabbing in wx.App.

-* Added wx.ColourDialogEvent, wx.DCTextBgColourChanger, wx.DCTextBgModeChanger,
-  wx.grid.GridCellDateRenderer, wx.grid.GridCellDateEditor, wx.SystemAppearance,
-  etc.

-* Many of the deprecated items in wxWidgets and wxPython are being or have
-  been removed. Be sure to test your code in a recent 4.0.x release with
-  warnings enabled so you can see which class, method or function calls you need
-  to change.

-* Bug fixes in wx.lib.calendar: key navigation across month boundaries is now
-  possible; key navigation now sets the date and fires the EVT_CALENDAR event;
-  setter APIs now set the date correctly (#1230).

-* Grafted on a EnableSystemTheme method to the classes which support it. This
-  can be used to disable the default system theme on Windows for native widgets
-  like wx.ListCtrl, wx.TreeCtrl and wx.dataview.DataViewCtrl. It has no effect
-  on the other platforms.

-* The wx.WS_EX_VALIDATE_RECURSIVELY extended style flag is obsolete, as it is
-  now the default (and only) behavior. The style flag has been added back into
-  wxPython for compatibility, but with a zero value. You can just stop using it

-  with Docker images.

 * Add some missing methods in wx.adv.BitmapComboBox (#1307)
 
-* Added the wx.svg package which contains code for parsing SVG (Scalable Vector
-  Graphics) files, and also code for integrating with wxPython. It can rasterize
-  the SVG to a wx.Bitmap of any size with no loss of quality, and it can also
-  render the SVG directly to a wx.GraphicsContext using the GC's drawing
-  primitives. (PR #1323)

-  maintaining its own pointer. This way, if the wxApp is created by C++ code
-  wxPython will still be able to get access to it. (#1126)

 * Added wrappers for the wx.ActivityIndicator class.

-* Fixed issues in PlotCanvas around displaying and using scrollbars. (#1428)
-
-* Added wx.msw.CHMHelpController, and also a wx.HelpController factory function
-  that creates an instance of the best Help Controller for the platform. (#1536)
-
-* Added wx.adv.GenericAnimationCtrl so the generic version of the animation classes
-  can be used even on the platforms that have a native version. Note that due to
-  internal changes to support both types of animations, some API changes in how
-  the Animation objects are created. See the AnimationCtrl.py sample in the demo
-  for the various usage patterns (#1579)

+  and wx.grid.GridBlockDiffResult classes, as well as associated new
+  methods in the wx.grid.Grid class. These provide a new way to
+  interact with blocks of selected cells, including an iterator
+  interface in wx.grid.GridBlocks which should be a more efficient
+  (time and memory) way to process large groups of selections.
