REL: v3.0.2 This is the second bug-fix release for the v3.0 series. - Un-breaks basemap which was broken by partially restoring private APIs for cartopy. - Fixes bug in warning code when used in an embedded context. - Fixes crash when using Tk and closing the first open window before showing it - Many documentation improvements. - Restore a corner case on ColorBar tick usage. - Change the default behavior of `matplotlib.use` to silently allow more 'safe' switching after auto-discovery, but before starting an event loop. - Improvements to bounding box calculations. - Provide the correct length for RcParams instances.
