+- Add option to mark a database as "sharded" so replication only connects to databases in the same shard, improving efficiency for sharded clusters.
+- Reliability: ensure we never attempt to reference an audit entry when one is not recorded and always create an audit entry during conflict/CRDT resolutions; this prevents orphaned blobs and guarantees they can be cleaned up.
+- Data integrity: assert that each transaction is recorded in the audit log.
+- Maintenance: throttle blob cleanup to reduce system load and add a final log message indicating when orphan cleanup finishes.
+- Fix: do not relocate records when their location is determined by id.
+- Add a final cleanup log message when orphan blob cleanup finishes.

+- Audit logging robustness:
+  - Always record an audit entry when conflict/CRDT resolutions are performed so all blobs retain a reference for eventual cleanup
+  - Avoid referencing an audit entry when audit logging is disabled; ensure a new version is created when resolving a cache entry that replaces an existing one
+- Blob cleanup improvements:
+  - Reduce cleanup rate to limit resource usage under load
+  - Add a final "orphan cleanup finished" log message
+- Sharded deployments: do not connect to nodes with a database connection if the database is marked as sharded and is not in the same shard
+- Stability: clear the application timeout timer to allow threads to exit gracefully when still running
+- HTTP/router: fix missing `urlPath` option on initial entry handler creation
+- Memory monitoring: make the near‑limit heap snapshot threshold configurable and enable taking a snapshot before exhausting heap memory
+- Data placement: avoid relocating records when location is determined by id
+- Developer ergonomics: fix camelCase conversion typos in resource code
