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 2018.
Thank you everyone (100+) who contributed to this release!
