ANN: Enable 5.2.0rc2 and Chaco 5.0.0rc1 Release Candidates

[Aaron Ayres]

Dear ETS Users,

We are very excited to announce that the Enable 5.2.0rc2 and Chaco 5.0.0rc1 release candidates are available on PyPI.  For information on what’s new, see the changelogs for enable and chaco.

To install them, you will need swig installed first, and more specifically swig 3.0.x (see issue involving swig 4).  For edm users this can easily be done via ``edm install swig``.  Otherwise you will need to use your package manager of choice to explicitly install swig 3 (e.g. ``brew install swig@3``). Then one can run

``pip install enable==5.2.0rc2 chaco==5.0.0rc1``

to install the release candidates.

Please try them out and let us know if you have any feedback / run into any issues.
