Apr 1, 2025April 2025: Generalized repository configuration for the percona-server-mongodb project by removing enterprise-specific entries from .git-blame-ignore-revs and CODEOWNERS. This reduces enterprise-specific maintenance, mitigates drift, and aligns configuration with standard contributor workflows. Result: cleaner project configuration, faster onboarding for new contributors, and lower risk of maintenance gaps.
