+- Transactions:
+  - Reset transaction timestamp on commit so reused transactions receive a new timestamp and do not conflict with prior operations
+  - Fix transaction timeout message to be accurate
+  - Disallow `get()` with null/undefined more precisely; prevent misuse and improve safety
+  - Fix handling of `create` with one/two arguments when `loadAsInstance=false`
+- Compaction and database maintenance:
+  - Move each compacted database into place immediately after its compaction completes
+  - Do not disable database deletion when a record count discrepancy is expected due to skipped deletion entries
+- Component loading/router:
+  - Await `loadDataFile` so subsequent components can access the loaded data
+  - Keep `scope.handleEntry()` promise-free while ensuring the initial load completes before loading the next component
+- API/OpenAPI:
+  - Fix hostname access for OpenAPI generation
+- Dependencies:
+  - Upgrade LMDB to address issue with returning loose pages to the free-list
+- Bug fixes:
+  - Correct nullish comparison logic to properly handle `null` values
+- Applications:
+  - Add Harper application lock file to avoid reinstalling application on every restart
