 ### Changed
 
 - Fixed event viewer arrow direction (previously inverted) — UI behavior corrected. - Thanks [@drnikcuk](https://github.com/drnikcuk) (Closes #772)
+- Region code options now intentionally include both `GB` (ISO 3166-1 standard) and `UK` (commonly used by EPG/XMLTV providers) to accommodate real-world EPG data variations. Many providers use `UK` in channel identifiers (e.g., `BBCOne.uk`) despite `GB` being the official ISO country code. Users should select the region code that matches their specific EPG provider's convention for optimal region-based EPG matching bonuses - Thanks [@bigpandaaaa](https://github.com/bigpandaaaa)
 - Channel number inputs in stream-to-channel creation modals no longer have a maximum value restriction, allowing users to enter any valid channel number supported by the database
 - Stream log parsing refactored to use factory pattern: Simplified `ChannelService.parse_and_store_stream_info()` to route parsing through specialized log parsers instead of inline program-specific logic (~150 lines of code removed)
 - Stream profile names in fixtures updated to use proper capitalization (ffmpeg → FFmpeg, streamlink → Streamlink)
