Release 8.0.0

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.

Notes on upgrading

• This release of TraitsUI now depends on Traits 6.2+ and pyface 7.2+. Also,
  deprecated code / modules have been removed. Namely, the
  :mod:traitsui.image <traitsui.image> module which was moved to
  pyface.image, editors_gen modules, Editor and EditorFactory factory
  methods on Toolkit objects, and more. For a complete list, see PRs in the
  "Removals" section below. These were all generally unused / deprecated for
  sometime. Also, importing directly from traitsui.editors has been
  deprecated. Please update imports to import directly from :mod:traitsui.api
  or :mod:traitsui.editors.api.
