wx.lib.pubsub is deprecated
---------------------------
Although it originally started as part of this project, for a long time the
content of the ``wx.lib.pubsub`` package has been coming from a fork of the
original, called PyPubSub. It's all the same code, but with just a different
access path. However, now that Python 2.7 support in PyPubSub is no longer being
maintained in the latest versions, it is now time for wxPython to disconnect
itself in order to not have to remain on the older version. This means that
``wx.lib.pubsub`` is now deprecated.
Switching to the official PyPubSub is simple however, just install the package::
pip install -U PyPubSub==3.3.0
And then change your import statements that are importing
``wx.lib.pubsub.whatever``, to just import ``pubsub.whatever`` instead. If you
are using Python3 and would like the newest version of PyPubSub then you can
drop the version number from the pip command above.
