wxPython 4.0.0a2 Release

wxPython 4.0.0a2 is now available at PyPI

This build of wxPython is based on the official wxWidgets 3.0.3 release.

This release is mostly various bug fixes and other tweaks, such as:

• Allow numpy arrays to be auto-converted to simple sequence value types like wx.Size, wx.Colour, etc.

• A couple of fixes to lib/agw/aui to prevent segfaults under OSX when AuiNotebook tabs are closed

• Fix wx._core.wxAssertionError in wx.lib.agw.aui when dragging a notebook tab

• Fix the [G|S]etClientData methods in wx.CommandEvent to behave the same way they are in wx.ClientDataContainer.

• Fix the SetFonts methods in wx.html classes

• Several fixes in wx.dataview related to overriding methods

• Fixed some flickering in wx.lib.agw.aui.framemanager

• Fixed problem with wrong implementation of wxNotebook::DeleteAllPages being called on Windows

• Added the missing wx.grid.GRID_AUTOSIZE flag

• Fixed crash due to the object created in an XmlSubclassFactory being destroyed too soon

• Fixed crash in wx.lib.agw.toasterbox

• Fixed crash when using wx.xrc.XmlSubclassFactory

• Fixed wx.grid.GridTableBase.GetValue and related methods to work more like they did in Classic, so non-string values can be used a little more easily.

Added building and bundling of the PDB files for wxWidgets and the wxPython extensions on Windows. Until a better place is found they will be downloadable from https://wxPython.org/Phoenix/release-extras, along with archives for the documentation as well as the demo and samples.
