[ANN] Matplotlib v2.2.0rc1


We are happy to release Matplotlib v2.2.0rc1!

This is a feature release which includes new functionality (along with many
bug-fixes). One of the hi-lights of this release is a constrained layout
manager, please see https://matplotlib.org/devdocs/users/whats_new.html for

API changes are at https://matplotlib.org/devdocs/api/api_changes.html

The rc can be installed via pip

   pip install --pre matplotlib

or via conda from conda-forge

   conda install -c conda-forge/label/rc matplotlib -c conda-forge

The goal is to do 2.2.0 final around Mar. 2, please test these out and
report bugs this week and next!

mpl2.2 will be the last feature release in the Matplotlib 2.x series and
the last feature release of Matplotlib to support python 2.7 and intend to
provide bug fixes to 2.2 until 2020. We are looking for someone to take
the lead on maintaining the 2.2.x branch, if you are interested please
reach out!

The next feature release after 2.2 will be 3.0 scheduled for July-August

Thank you everyone (100+) who contributed to this release!
