============
This is a major version update to add support for Python 3.11, PySide 6.4+, and
TraitsUI 8. As part of this update, a number of backwards-incompatible changes
were made. Perhaps the most significant of these was the removal of the
partially implemented and buggy OpenGL Kiva backend, but it also included
removing support for legacy Numeric APIs, changing modules with "qt4" in their
name to use "qt" instead, some changes to make the various Kiva APIs more
consistent, and some changes to the mapping of font families to bring them in
line with documentation and other libraries.
Building Enable, with its complex dependencies has sometimes been challenging
for users, so this release includes Github actions that use cibuildwheel to
automatically build binary wheels across a wide variety of Python versions,
operating systems and architectures and upload them to PyPI. This should make
pip-based installs of Enable significantly easier.
Finally, as is usual for a release, there are a number of smaller bugfixes and
minor improvements, such as bringing the PyCairo and Quartz backends back into
a working state.
