Redmine

Redmine 6.0 and later supports MySQL 8.0 or later only (#39579). Additionally, the dependency library with_advisory_lock also no longer supports MySQL 5.7, as stated in its README.md.

However, config/database.yml.example still contains comments for MySQL 5.7 and earlier.

This patch removes obsolete MySQL 5.7-related comments to match the current support policy and avoid confusion.
