Releases: libmamba 1.2.0, libmambapy 1.2.0, mamba 1.2.0, micromamba 1.2.0
Date: 16 Jan 2023

This release contains some speed improvements: download repodata faster as zstd encoded files (configure using
repodata_use_zst: true in your ~/.mambarc file). Also, .conda file extraction is now faster, a prefix
with spaces works better thanks to a new "shebang" style and the micromamba package compress and transmute
commands produce better conda packages.
