Joining SPEC as a Core Project
by Elliott Sales de Andrade May 26, 2021

May 26, 2021

Hi all, As you may know already from our previous dev meetings, I am on the steering committee of a new project to better coordinate the scientific Python ecosystem through a mechanism called the Scientific Python Ecosystem Coordination (SPEC) process: https://scientific-python.org/specs/ We've already recruited a SPEC steering committee: https://scientific-python.org/specs/steering-committee/ And we are now recruiting Core Projects: https://scientific-python.org/specs/core-projects/ Matplotlib is currently listed as a Core Project with draft status. Before the SciPy conference in July, we would like to list Matplotlib as a Core Project (i.e., with the draft notice removed). Being a Core Project requires that we endorse SPEC documents that we support, but this is entirely opt-in, and so far the proposals are something we're interested in anyway. I will put this on the meeting agenda for tomorrow to discuss. We would like to put this in by June 9th, which gives us a few weeks, but I don't think this will be controversial. -- Elliott

Understanding Our Contributors - NumFOCUS survey - We Value your Input
by Thomas Caswell May 23, 2021

May 23, 2021

Folks, Matplotlib is participating in a research project being conducted by NumFOCUS <https://numfocus.org/>, our fiscal sponsorship organization. The research is looking into understanding the diversity, inclusion and barriers to participation within NumFOCUS-sponsored projects and the wider open source community. The survey <https://numfocus.typeform.com/to/W6Bax8eq> will take 15-20 mn to complete. We’d appreciate your contribution by May 31, 2021. The results of this survey will help NumFOCUS work closely with our projects to develop practices that will lead to project success around diversity, inclusion and sustainability. Click here to participate into the survey <https://numfocus.typeform.com/to/W6Bax8eq> Thank you for your participation !

Hi all, We are pleased to announce the release of Matplotlib 3.4.2. This is the second bug fix release of the 3.4.x series. Pre-built wheels are available for most major platforms, and can be installed using `pip install matplotlib==3.4.2`. Other packages may also be available already; please check with your preferred source. We would like to thank the 13 authors over 46 pull requests for their contributions to this release. This release contains several critical bug fixes: * Generate wheels usable on older PyPy7.3.{0,1} * Fix compatibility with Python 3.10 * Add |subplot_mosaic| Axes in the order the user gave them to us * Correctly handle 'none' /facecolors/ in |do_3d_projection| * Ensure that Matplotlib is importable even if there's no HOME * Fix |CenteredNorm| with /halfrange/ * Fix |bar_label| for bars with NaN values * Fix clip paths when zoomed such that they are outside the figure * Fix creation of |RangeSlider| with /valinit/ * Fix handling of "d" glyph in backend_ps, fixing EPS output * Fix handling of datetime coordinates in |pcolormesh| with Pandas * Fix processing of some |errorbar| arguments * Fix removal of shared polar Axes * Fix resetting grid visibility * Fix subfigure indexing error and tight bbox * Fix textbox cursor color * Fix TkAgg event loop error on window close * Ignore errors for sip with no setapi (Qt4Agg import errors) For further details on new features, please see the What's new in Matplotlib 3.4.0 page: https://matplotlib.org/3.4.0/users/whats_new.html and for details of bugs fixed in 3.4.2, see the milestone on GitHub: https://github.com/matplotlib/matplotlib/milestone/63?closed=1 This release is signed by my GPG key.
