- Fixed numerous bugs across ActiveSupport, ActiveRecord, ActionView, ActionPack, Railties and related components (e.g., hash key transformation, cache and query handling, stale association detection, route reload issues).
- Added new capabilities: per‑database schema format configuration, hash source support in Content Security Policy, and included the terser rollup plugin as a dev dependency.
- Deprecated the Aws::S3::Object upload stream API in ActiveStorage.
