12.1: no action items (1 version)

Release notes from github.com/jellyfin/jellyfin/releases, and the official release blog, checked 17 hours ago. Only text the vendor marks as breaking, or puts in a warning/caution/important/stop/notice note, or a plain note, is shown (a note that only says when security advisories will be published is not); read the full notes for anything else. Jellyfin's release notes mark breaking changes only from 12.0 (“Breaking and behavior changes”). Sections titled Important Release Notes, Important Notes, Notes on Updating and the 10.4.1 Base URL change, and a Packaging section (12.0: platforms no longer built) are quoted as “Note”; so is the Release Notes section of x.y.0 releases. In patch releases, whose Release Notes list bug fixes, only paragraphs with a bold WARNING, STOP, NOTICE or NOTE marker are quoted. From the release blog (jellyfin.org/posts, 10.9.0 onward) the Breaking Changes sections are quoted as “Breaking”, and the TL; DR, Removal of …, Deprecation of …, Free Space Checks and Changes you may notice after upgrading sections as “Note”; four bullets of the 10.9.0 “The Big Changes” lists that remove or reset something (DLNA, PIN login, minimum FFmpeg, FFmpeg path) are quoted as “Note” too.
