Fix metadata to allow releasing.

regionmask v0.12.0 adds a new approximate fractional overlap mask, fixes a number of issues with certain natural earth regions and restores compatibility with the upcoming xarray release.

regionmask v0.11.0 checks if regions are overlapping per default. It also fixes some minor bugs and bumps the supported versions.

regionmask v0.10.0 brings support for cf_xarray, which allows to auto-detect coordinate names using and handling of region names in 2D masks. It also supports shapely 2.0 and creating overlapping 3D masks has become faster.

Version 0.9.0 contains some exiting improvements: overlapping regions and unstructured grids can now be masked correctly. Further, Regions can now be round-tripped to geopandas.GeoDataFrame objects. The new version also adds PRUDENCE regions and a more stable handling of naturalearth regions.

Many thanks to the contributors to the v0.9.0 release: Aaron Spring, Mathias Hauser, and Ruth Lorenz!

Version 0.8.0 contains an important bugfix, improves the handling of wrapped longitudes, can create masks for coordinates and regions that do not have a lat/ lon coordinate reference system and masks for irregular and 2D grids are created faster if the optional dependency pygeos is installed.

Version 0.7.0 is mostly a maintenance version. It drops python 2.7 support, accompanies the move of the repo to the regionmask organisation (regionmask/regionmask), finalizes a number of deprecations, and restores compatibility with xarray 0.19.0.

Minor bugfix release that corrects a problem occurring only in python 2.7 which could lead to wrong coordinates of 3D masks derived with mask_3D and mask_3D_geopandas. It's recommended that users of regionmask v0.6 and python 2.7 update to the new version.

There were some last updates to the AR6 regions (regionmask.defined_regions.ar6).
If you use the AR6 regions please update the package. There were no functional changes.

Version 0.6.0 offers better support for shapefiles (via geopandas) and can directly create 3D boolean masks
which play nicely with xarray's weighted.mean(...) function. It also includes a number of optimizations and bug fixes.
