Changelog

Sourced from conda-incubator/setup-miniconda's changelog.

v4.0.1 (2026-04-24)

Fixes

• Fix MultipleKeysError on conda 25.11+ when a user-supplied condarc-file already declares auto_activate: now only one of auto_activate / auto_activate_base is written to .condarc, preferring whichever key the user's existing condarc uses.
• Add auto_activate to the boolean coercion set so its value is serialized as a YAML boolean when it is the chosen canonical key.
• Add local_repodata_ttl to KNOWN_CONDARC_KEYS to silence a spurious "Unrecognized condarc key" warning for a valid conda key.
