Description

conda-forge infrastructure holds common configurations and settings for key pieces of the conda-forge infrastructure.
Between 2025-02-10 and 2025-04-01, conda-forge infrastructure used the wrong token for Azure's cf-staging access.

The security logs on anaconda.org were check for any packages that were not copied from the cf-staging to the conda-forge channel and none were found.
