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.
- From July 2023 on,
conda-libmamba-solverwill 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
classicwill 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!
