Dear all,

I am pleased to announce the release of mplcairo 0.4.

mplcairo is a Matplotlib backend based on the well-known cairo library,
supporting output to both raster (including interactively) and vector
formats.  In other words, it provides the functionality of Matplotlib's
{,qt5,gtk3,wx,tk,macos}{agg,cairo}, pdf, ps, and svg backends.

Per Matplotlib's standard API, the backend can be selected by calling


or setting your MPLBACKEND environment variable to `module://mplcairo.qt`
for Qt5, and similarly for other toolkits.

mplcairo 0.4 adds support for Matplotlib 3.4, support for retrieving
underlying cairo contexts, as well as the usual bugfixes over 0.3.
