Be aware,
Jellyfin uses semantic versioning. All releases will have versions in the X.Y.Z format, starting from 10.0.0. Note however that the 10.Y.Z release chain represents the "cleanup" of the codebase, so it should be accepted that 10.Y.Z breaks all compatibility, at some point, with previous Emby-compatible interfaces, and may also break compatibility with previous 10.Y releases if required for later cleanup work
