I'm pleased to announce the release of matplotlib 1.2.1. This is a bug release and improves stability and quality over the 1.2.0 release from four months ago. All users on 1.2.0 are encouraged to upgrade. Since github no longer provides download hosting, our tarballs and binaries are back on SourceForge, and we have a master index of downloads here: http://matplotlib.org/downloads <http://matplotlib.org/downloads.html> Highlights include: - Usage of deprecated APIs in matplotlib are now displayed by default on all Python versions - Agg backend: Cleaner rendering of rectilinear lines when snapping to pixel boundaries, and fixes rendering bugs when using clip paths - Python 3: Fixes a number of missed Python 3 compatibility problems - Histograms and stacked histograms have a number of important bugfixes - Compatibility with more 3rd-party TrueType fonts - SVG backend: Image support in SVG output is consistent with other backends - Qt backend: Fixes leaking of window objects in Qt backend - hexbin with a log scale now works correctly - autoscaling works better on 3D plots - ...and numerous others. Enjoy! As always, there are number of good ways to get help with matplotlib listed on the homepage at http://matplotlib.org/ and I thank everyone for their continued support of this project.
