- Single-channel and selected-channel auto-match always run, even when the channel already has EPG assigned; match-all (no channel IDs) still only processes channels without EPG.
The auto-sync overhaul added a [start, end] range and a shared numbering picker, but each mode's UI exposes only a subset of the persisted fields (Provider's "Start #" writes channel_numbering_fallback; Next Available exposes no Start/End) while the backend read auto_sync_channel_start and auto_sync_channel_end in every mode. Switching modes never resets the others, so a stale or auto-computed value silently changed numbering.
- Provider mode honors the provider-supplied number (stream_chno) verbatim; the group's Start (channel_numbering_fallback) and End bound only the fallback for streams the provider did not number. auto_sync_channel_start is no longer applied in provider mode.
- Next Available ignores End, since its UI exposes no range.
- Range enforcement (the overflow-delete) runs in fixed mode only, the one mode with a user-set [start, end] range.
- Provider mode gains the Start>End guard fixed mode already had, so an inverted fallback range cannot fail every numberless stream.
Includes backend and frontend regression tests.
- Precompute base URL and logo path components once per request to reduce redundant calls to `build_absolute_uri_with_port()`, enhancing performance.
- Update logo URL construction for both cached and direct logos to utilize the precomputed values, ensuring consistency and efficiency in URL handling.
- Precompute base URLs for M3U stream and logo paths to reduce redundant calls to `build_absolute_uri_with_port()`, improving performance.
- Update the generation of EPG and stream URLs to utilize the precomputed base URL, ensuring consistency and efficiency in URL handling.
- Enhance the handling of logo URLs by consolidating logic for cached and direct logo retrieval, streamlining the process and reducing overhead.
- Refactored HDHR API views to utilize `build_absolute_uri_with_port()` for generating URLs, ensuring correct handling of non-standard ports in lineup and discovery responses.
- Addressed a bug where the EPG channel list did not refresh after a source finished parsing channels due to the `epg_refresh` WebSocket handler using a stale snapshot. The handler now correctly reads the current store state and ensures `fetchEPGData()` is called upon completion of channel parsing.
- Updated tests to verify that the frontend receives the correct parsing completion signals.
Add support for automatically applying channel logos from EPG data during refresh. Introduce a new toggle in the UI for enabling/disabling this feature, and update the backend to handle both channel IDs and EPG source IDs for logo application. Enhance the logo application task to process large libraries efficiently in chunks, improving performance and memory usage. Update changelog to reflect these changes.
Remove the _sd_send_ws_sync function and replace its usage with send_epg_update in the fetch_schedules_direct function. This change simplifies the code by ensuring all WebSocket updates are sent through a single function, improving maintainability and consistency in handling EPG updates.
Introduce a new poster style selection feature in the EPG settings, allowing users to choose their preferred artwork style. Update the logic for fetching and displaying program artwork from Schedules Direct, ensuring that the selected style is honored with appropriate fallbacks. Set default poster art to 'primary'. Add comprehensive tests to validate the poster selection functionality across various scenarios.
Add a new task to fetch program artwork from Schedules Direct and auto-apply logos to channels based on EPG data. Enhance the existing logic to handle poster backfill and update program records with fetched artwork. Readd the WebSocket handler to manage IP lookup events and adjust the EPGsTable component to display relevant credentials based on the source type.
Update the variable name in the EPG settings to better reflect its purpose. Adjust related logic in the UI to ensure consistent handling of the auto-apply feature for SD logos.
The compact repack read its channels with no ORDER BY, so the pack followed PostgreSQL's physical row order. That order drifts after the
UPDATEs each repack issues, so successive syncs
packed the same channels into different numbers within the configured range. Auto-synced channel numbers reshuffled on every sync even when the provider had not changed.
- Add .order_by("id") to the _repack_inner channel query so the pack is deterministic. id order is creation order, which tracks the provider stream order used by the default "provider" sort.
- Add c.id as a secondary key to the name / tvg_id / updated_at sorts so equal values (e.g. blank tvg_id) break ties deterministically instead of churning.
- Add a deterministic regression test that forces a physical heap reorder (CLUSTER) and asserts two consecutive repacks produce identical channel numbers.
Build absolute poster proxy URLs via build_absolute_uri_with_port so
program detail images resolve correctly in dev and behind reverse
proxies. Backfill sd_icon for programs when poster fetch is enabled
but a delta refresh skips program metadata. Add a dev-mode frontend
fallback for relative image paths and correct the poster caching
description in the SD settings UI.
Add User-Agent header to API requests in ProgramViewSet for better tracking. Update cast processing logic in fetch_schedules_direct to align with XMLTV standards, ensuring proper categorization of main cast and guest stars.
ProgramViewSet.get_permissions() was falling through to Authenticated()
for the poster action since it wasn't in permission_classes_by_action.
Add explicit AllowAny check for the poster action.
Store credential Redis keys at reserve so release works when the profile row is deleted. Return reserve failure reasons to avoid fingerprint DB queries on logging paths. Document unlimited profile bypass in pool logic and Server Group UI.

Add updateSDSettings method to API client for SD logo style and settings
management. Add fetchEPGData and requeryChannels calls after EPG match
completion to ensure UI refreshes immediately. Add SD logo style picker
and cache-busting for channel logos.
Add content_advisory, content_ratings, event_details, runtime to
ProgramDetailSerializer. Display content advisory, sports venue/teams,
and first-aired date in ProgramDetailModal.
Streams matched by hash during refresh were not updating channel_group_id,
causing cleanup to delete all streams when group IDs change (e.g., after
migration reset). Adds channel_group_id to comparison, assignment, only()
fetch, and bulk_update in both standard and XC processing paths.
