Recent Releases of enable

enable - Version 6.0.0

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.

Thanks to:

  • Mark Dickinson

  • Didrik Pinte
  • Corran Webster
  • John Wiggins

Enhancements

  • Move kiva.image to kiva.oldagg and make kiva.image a stub (#1054)

enable - Version 5.3.1

This is a bugfix release that aims to improve compatibility and completeness of the various Kiva backends. In particular, there are improvements for font selection and rendering, and some fixes for path and curve rendering (particularly for arcs). There are still some discrepancies in how things are drawn, but it is more likely that something reasonable will be produced on all backends.

This also includes some fixes provided by Brecht Machiels to return the wxPython backend to a working condition.

On the build and CI front, we have added SWIG to the pyproject.toml, and no longer ship any Cython-generated C++ files. With these changes it should be possible to pip install Enable in an environment with the appropriate C/C++ compilers.
