 - **`libpq-dev` removed from both build and runtime stages.** The project uses `psycopg[binary]` (psycopg3), which bundles its own statically linked copy of libpq inside the wheel. No system libpq headers or shared library are needed at build or runtime.
 - **Database driver upgraded from `psycopg2` to `psycopg3` (`psycopg[binary]`).** psycopg3 rewrote its network I/O layer in Python, so `gevent`'s `monkey.patch_all()` makes it gevent-cooperative without any additional patching. The `psycogreen` dependency and its driver-patching block in `gevent_patch.py` have been removed. Django's native psycopg3 connection pool is explicitly disabled (`pool: False`) so `django-db-geventpool` remains in sole control of connection lifecycle. The `dropdb` management command was updated to the `psycopg` API (`psycopg.connect`, `psycopg.sql`).
 - **Frontend unit tests extended to additional form components and the Guide page.** `ProgramRecordingModal`, `Recording`, `RecordingDetailsModal`, `RecurringRuleModal`, `ScheduleInput`, `SeriesRecordingModal`, `SeriesRuleEditorModal`, `Stream`, `StreamProfile`, `SuperuserForm`, `User`, `UserAgent`, and `VODCategoryFilter` now have Vitest + Testing Library test suites. Business logic was extracted from these components into corresponding utility modules and is exercised through the new tests. The Guide page was similarly refactored with extracted utils, and `dateTimeUtils.js` was extended to support the new test coverage. — Thanks [@nick4810](https://github.com/nick4810)
+- **Official plugin repository manifest URL moved to GitHub Pages.** The default `OFFICIAL_REPO_URL` now points to `https://dispatcharr.github.io/Plugins/manifest.json` instead of the raw GitHub content URL. GitHub Pages avoids opaque caching on raw content that could serve stale manifests without indication. A data migration updates existing `PluginRepo` rows marked `is_official=True` in place; fresh installs pick up the new URL from the model default after the seed migration runs. — Thanks [@sethwv](https://github.com/sethwv)
 
 ### Performance

 - **Restoring a backup from an older version left the database with missing schema.** The restore task ran `pg_restore` which replaced the entire database (including the `django_migrations` table) but did not run migrations afterward. If the backup predated a schema migration, the restored database was missing tables and columns added by those migrations, causing 500 errors on every API call. `migrate --noinput` now runs automatically after every restore. The success notification also now recommends a restart to clear stale service state.
 - **Cast and actors lists were silently truncated to the first name.** When a provider returns `cast` or `actors` as a JSON array, the helper used during both movie and series basic sync and movie advanced refresh only extracted the first element. All names in the array are now joined into a comma-separated string. Providers that return cast as a plain string are unaffected.
 - **Channel Group Override interactions in compact numbering and override display.** Two related bugs surfaced when Channel Group Override was used with auto-synced channels. First, compact numbering silently failed: with an override on the source `ChannelGroupM3UAccount`, sync stores channels under the override target group's id (not the source group id), so hide/unhide/repack operations all missed their channels and slot accounting broke silently (hidden channels kept their numbers, unhides got none, repack saw zero channels). The compact paths now include an override-aware fallback to match channels under both source and override-target group ids. Second, the clear-override reset button disappeared when an override's stored value coincidentally matched the provider value. The frontend `isFormFieldOverridden` function was value-based only; it now also checks for a persisted override row regardless of value, so the reset button remains available to clear any override. (Fixes #1263, Fixes #1276) — Thanks [@CodeBormen](https://github.com/CodeBormen)
+- **Compact numbering repack is now idempotent.** Auto-synced channel numbers reshuffled within their configured range on every sync, even when the provider returned no changes. The compact repack queried channels with no `ORDER BY`, so packing followed PostgreSQL's physical row order, which drifts after each repack's UPDATEs and autovacuum. The channel query now uses `.order_by("id")` (creation order tracks provider stream order for the default "provider" sort), and explicit name / tvg_id / updated_at sorts carry `c.id` as a secondary tiebreaker so equal values keep a stable relative order instead of churning. (Fixes #1321) — Thanks [@CodeBormen](https://github.com/CodeBormen)
