- Added async replication improvements: CompareDigests mode, corrected frequency handling, and fixed a race condition in the scheduler dispatch logic.
- Implemented server‑side usage limits (guardrails) for objects, collections, tenants, and shards.
- Updated CI and QA tooling: switched to Ubicloud runners and Ubuntu 24.04 ARM runners, disabled Dependabot job reruns, added multi‑arch Docker support, and enhanced the qa script with branch parameters and user assignment.
