'Mambaforge' variants are now equivalent to 'Miniforge3'. In the future, we will ignore with a warning and use 'Miniforge3'. Eventually, using 'Mambaforge' will throw an error. Please change to 'Miniforge3' at your earliest convenience.

Mambaforge is now deprecated! Future Miniforge releases will NOT build Mambaforge installers. We advise you switch to Miniforge at your earliest convenience. More details at https://conda-forge.org/news/2024/07/29/sunsetting-mambaforge/. If you require Mambaforge, you may pin your installer to one found in https://github.com/conda-forge/miniforge/releases/tag/24.7.1-0
