 ### Fixed
 
+- XC API `added` field type inconsistencies: `get_live_streams` and `get_vod_info` now return the `added` field as a string (e.g., `"1708300800"`) instead of an integer, fixing compatibility with XC clients that have strict JSON serializers (such as Jellyfin's Xtream Library plugin). (Closes #978)
 - Stream Profile form User-Agent not populating when editing: The User-Agent field was not correctly loaded from the existing profile when opening the edit modal. (Fixes #650)
 - VOD proxy connection counter leak on client disconnect: Fixed a connection leak in the VOD proxy where connection counters were not properly decremented when clients disconnected, causing the connection pool to lose track of available connections. The multi-worker connection manager now correctly handles client disconnection events across all proxy configurations. Includes three key fixes: (1) Replaced GET-check-INCR race condition with atomic INCR-first-then-check pattern in both connection managers to prevent concurrent requests exceeding max_streams; (2) Decrement profile counter directly in stream generator exit paths instead of deferring to daemon thread cleanup; (3) Decrement profile counter on create_connection() failure to release reserved slots. (Fixes #962, #971, #451, #533) - Thanks [@CodeBormen](https://github.com/CodeBormen)
 - XC profile refresh credential extraction with sub-paths: Fixed credential extraction in `get_transformed_credentials()` to use negative indices anchored to the known tail structure instead of hardcoded indices that broke when server URLs contained sub-paths (e.g., `http://server.com/portal/a/`). This ensures XC accounts with sub-paths in their server URLs work correctly for profile refreshes. (Fixes #945) - Thanks [@CodeBormen](https://github.com/CodeBormen)
