Traits

-------------

This is a major release that provides support for PySide 6.4 and 6.5 as well
as Python 3.11. It includes a number of backwards-incompatible changes
following the example of Pyface 8.0.0, most notable is moving the
`traitsui.qt4.*` modules to `traitsui.qt.*`. As with Pyface 8.0 we include
a backwards-compatibility mode which allows importing from the 'qt4' namespace
via:

- setting the ETS toolkit to `"qt4"`
- setting the ETS_QT4_IMPORTS environment variable
- manually adding appropriate finders to sys.meta_path

This release also removes a number of features deprecated since TraitsUI 7.0.
