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.

Update

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.

TL;DR​

  • From July 2023 on, 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.
  • From September 2023 on, the default conda solver will be libmamba. classic will be available via --solver=classic, if needed.
  • At some point in the future, we'll discuss whether the classic solver is kept around, maintained as a separate plugin, and/or deprecated for good. Feedback welcome!

✨ What's New? ✨​

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.
