ANN: Matplotlib 2.2.0 released


We are happy to announce the release of Matplotlib 2.2.0!

The first release of the v2.2 LTS series and the last version of
Matplotlib to support python2. There will be bug-fix release for this
series until 2020.

This release includes new features including:

- An experimental constrained layout manager
- Color blind friendly color map (cividis) and color cycle
- native support for numpy.datetime64 types
- animated gif writing via pillow
- TkAgg now works with pypy
- cairo based backends for Qt, Tk, and WX

For full details see

There are several API changes in this release:

- To support the constrained layout Matplotlib has a new required
   dependency (kiwisolver).
- The `` module has been removed, development has
   moved to a stand-alone project.

For more details see

The next feature release of Matplotlib will be 3.0, targeted for July 2018
will support python 3.5+.

We are looking for a release manager for the 2.2.x series.

Thank you again to everyone (~100) people who helped to get the release
done and out the door!
