The September 2023 releases included updates to five conda community projects: conda, conda-build, conda-libmamba-solver, conda-index, and pycosat! 🎉 Each of these have been released to both main and conda-forge.
Changes in Conda 23.9.0
To update conda, run:
conda install -n base conda=23.9.0
📢 Special Announcement 📢
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.
