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.

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.
Over a year ago, the conda team at Anaconda, together with conda developers at Quansight and QuantStack, announced the release of a new solver for conda based on the libraries that the mamba project had developed on top of the venerable libsolv project.
The default solver change for conda will be occurring in a special 23.10.0 release (not in 23.9.0). See the special announcement here.
conda-libmamba-solver will be part of the various installers. The default conda solver is still classic. Look out for the release of miniconda, Anaconda Distribution and miniforge soon.libmamba. classic will be available via --solver=classic, if needed.
May releases are here! 🎊 Conda 23.5.0, conda-build 3.25.0, and conda-libmamba-solver 23.5.0 are now available on both main and conda-forge:
To update conda, run:
conda install -n base conda=23.5.0
The long-awaited conda doctor subcommand plugin has been implemented! The related conda issue is over nine years old and has been a regularly requested feature. The conda doctor command enables conda users to detect any packages with files missing (i.e., corrupt packages) in their conda environment.
