With this 23.10.0 release we are changing the default solver of conda to conda-libmamba-solver! πŸ₯³ πŸš€β€‹

libmamba builds on libsolv, a much faster solver from openSUSE. The previous "classic" solver is based on pycosat/Picosat and will remain part of conda for the foreseeable future. A fallback is possible and available.

info

Conda's default solver will change to conda-libmamba-solver in a special 23.10.0 release in the near future!

You can already benefit from conda-libmamba-solver today by configuring your conda installation to use it (e.g. by running conda config --set solver libmamba).

The current "classic" solver is based on pycosat/Picosat and will remain part of conda for the foreseeable future. A fallback is possible and available.

Additional details on this change as well as the full announcement can be found in the conda 23.9.0 changelog.
