@ -118,6 +118,13 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- **`update_stream_profile()` uses a Redis pipeline** for the old-profile DECR + key update + new-profile INCR sequence, preventing counter drift if the process crashes between operations.
- **`stream_generator._cleanup()`** now falls back to `Stream.objects.get()` when the channel UUID resolves to a preview flow rather than a normal channel, rather than silently skipping the slot release.
- **VOD `cleanup_persistent_connection()`** fallback DECR is now conditional: it only decrements the profile counter when the connection tracking key had already expired by TTL (i.e., `remove_connection()` would have skipped the DECR), preventing double-decrements when the key is still present.
- Ghost clients and channels stuck in `INITIALIZING` state in the TS proxy (Fixes #695, #669) — Thanks [@CodeBormen](https://github.com/CodeBormen)
- **`INITIALIZING` added to cleanup grace period monitoring**: channels stuck in `INITIALIZING` are now surfaced by the cleanup task and torn down, preventing indefinite hangs when stream startup fails.
- **Orphaned channel cleanup validates client SET entries**: the cleanup task now cross-checks client SET members against actual metadata hashes; ghost SET entries are removed and the channel is torn down cleanly when no real clients remain.
- **Stats page self-heals**: ghost client SET entries are detected and removed when reading channel stats, preventing stale entries from inflating the active-client count.
- **`remove_ghost_clients()` extracted to `ClientManager`**: ghost-detection logic is now a single authoritative helper, callable with an optional pre-fetched `client_ids` set to eliminate a redundant Redis `SMEMBERS` round-trip when the caller already holds the set.
- **Ownership TTL fallback**: the error-state writer now triggers via ownership check _or_ state guard fallback, so a channel stuck in a pre-active state is correctly marked `ERROR` even when the ownership TTL expired during retries.
- **Missing `SOURCE_BITRATE` / `FFMPEG_BITRATE` metadata constants** added to `ChannelMetadataField`, preventing `AttributeError` on detailed channel stats reads.
- TS proxy client stream lag recovery now only bumps clients forward when their next required chunk has genuinely expired from Redis (TTL), rather than unconditionally jumping if they fell more than 50 chunks behind. Clients are repositioned to the oldest available chunk (minimum data loss) using an atomic server-side Lua binary search, falling back to near the buffer head if nothing is available.
- TS proxy streams dying after 30–200 seconds in multi-worker uWSGI/Celery deployments, caused by three interrelated bugs. (Fixes #992, #980) - Thanks [@PFalko](https://github.com/PFalko)
- **Double ProxyServer instantiation**: `ProxyConfig.ready()` called `TSProxyServer()` directly while `TSProxyConfig.ready()` also called `TSProxyServer.get_instance()`, creating two instances per worker — each with its own cleanup thread. The orphaned thread could not extend ownership because it had no entries in `stream_managers`. Fixed by using `TSProxyServer.get_instance()` in `ProxyConfig.ready()`.
