+#### Bugfixes {: #3.108.1-rest-api-bugfix }

+- Optimized cleanup_old_versions() by rewriting protected_versions() to avoid expensive JOINs
+  on large databases and deferring the content_ids field during version deletion.
+  [#7594](https://github.com/pulp/pulpcore/issues/7594)
+- Added new setting `TASK_PREFER_DEFER` to always defer immediate tasks to a task worker. Useful for systems with slow databases that frequently timeout immediate tasks.
