+## v0.1.24
+
+### Bug Fixes
+
+**Autotask Integration:**
+- Fixed Autotask ticket description being cleared when resolving tickets
+  - Root cause: The `update_ticket_resolution_safe` function was performing a GET to retrieve the ticket, then a PUT to update the resolution field, but the `description` field was not included in the PUT payload
+  - Impact: When clicking "Resolve" on an Autotask ticket, the description would be set to NULL by the Autotask API
+  - Solution: Added `description` to the `optional_fields` list in `update_ticket_resolution_safe` so the original description is preserved from the GET response and included in the PUT request
+  - Location: `containers/backupchecks/src/backend/app/integrations/autotask/client.py` line 672
+
 ## v0.1.23
 
 This comprehensive release introduces a complete built-in documentation system with 33 pages covering all features, enhanced audit logging for compliance and troubleshooting, timezone-aware datetime display throughout the application, and numerous Autotask PSA integration improvements for better usability and workflow efficiency.
