wxPython 4.3.0 is now available at PyPI, with some additional files at GitHub Release

Starting with this release wxPython has switched to tracking the wxWidgets master branch (version 3.3.x) for the wxWidgets source code, which wxPython is built upon, and which is included in the wxPython source archives.

Do note that the wxWidgets 3.3.x releases are API/ABI unstable, so there may be API changes/instability between wxPython 4.3.x releases.

New and improved in this release: * Fix wx.svg to work with cython 3.1 generated code.

• Populate wx.svg with _nanosvg enum values

• Bugfix in hypertreelist. Add missing attribute _x_maincol to constructor of TreeListMainWindow.

• Migrate to build with wxWidgets 3.3 branch

• Fix compile warning in ListClass contains methods

• Fix build with setuptools 81+

• Modernize/update documentation theme

• Add several methods to FlatMenu and FlatMenuItem to mimic wx better

• Make flatmenu's repositioning logic multi-monitor aware

• Remove no-op code from aui for deleting panes created referring to inexistent windows that were created in the process of loading a perspective. Rationale: All panes that refer to inexistent windows created when loading a perspective that is otherwise valid are already removed during update.

• Fix SuperToolTip window too small when footerBmp is used

• Fix incorrect module paths in TipProvider documentation

• Expose MSWEnableDarkMode/wxDarkModeSettings on all platforms at compile time

• show CB_READONLY in BitmapComboBox demo
