I'm a bit late on this, but Matplotlib 3.2.1 was released a couple days ago.
This is the first bugfix release of the 3.2.x series.
This release contains several critical bug-fixes:
* fix Quiver.set_UVC calls with scalar inputs
* fix bezier.get_parallels failure from floating point rounding errors
* fix markers specified as tuples (polygons, stars, or asterisks)
* fix saving PNGs to file objects in some places
* fix saving figures using the nbAgg/notebook backend
* fix saving with tight layout using the PGF backend
* fix setting custom datapath in rcParams (note: it is still deprecated)
* fix various issues running setup.py in non-CI environments
* fix xpdf distiller
* various minor bug and documentation fixes
PS, since there was no release announcement for 3.2.0, here are its
* default image interpolation is now `'antialiased'` to better handle
down-sampling and reduce artifacts when up-sampling by small ratios.
* change when ticks switch to using an offset to improve readability
* improvements to auto-scaling and auto-limits
* `DivergingNorm` has been renamed to `TwoSlopeNorm`
* support for 3 and 4 digit hex colors (`#123` maps to `#112233`)
* improvements to Logit scale ticker and formatter
* control of where errorbars start getting placed with `errorevery`
* correct kerning when laying out text
* improvements to MovieRegistry
