Patch 2026.05.2

[freearhey]

This update adds the x-tvg-url attribute to playlists containing links to available guides:

#EXTM3U x-tvg-url="https://example2.com/guide.xml,https://example.com/guide.xml.gz"

The list of guides will be updated automatically when the playlist:generate, playlist:update, and playlist:format scripts are run, and will include only those guides that feature channels from the current playlist.
