- Updated Redis cache and Action Cable adapters to work with redis‑rb 5.0, dropping support for redis‑rb 3.x (breaking change).
- Added timestamptz as a time‑zone‑aware type and timezone‑aware range handling for PostgreSQL; removed arity restriction on custom ActiveSupport::Deprecation behaviors.
- Fixed multiple bugs: stale relation cache version, async load on association proxies, large‑file proxy downloads in ActiveStorage, Server‑Timing header overwrites, and removed Que adapter deprecation warning.
