Near-daily alphas grinding toward parity between desktop and every mobile OS
A side-by-side editorial comparison of Immich and Jellyfin — release velocity, themes, recent moves, and the top alternatives to consider.
Immich is four release candidates into v3 with every feature note published somewhere else.
The visible release stream is a v3.0.0 RC series — rc.0 through rc.3, cut over eleven days in June — and each entry is the same template: a release-candidate disclaimer, a database and library backup warning, and instructions to move IMMICH_VERSION from v2 to v3 or the rolling v3-rc tag. The actual release notes live on a work-in-progress preview page outside the changelog.
Jellyfin drops the 10. prefix and puts 12.0 through a three-candidate preview.
The project is running a 12.0 release candidate series alongside a 10.11.x stable line that has thinned to single-fix releases. The RC notes carry one substantive announcement: versioning drops the leading 10., so 10.11.x becomes 12.x, on the reasoning that the hard API break the old scheme anticipated is no longer planned. The stable line's last two releases were three GHSA security fixes and a UserManager lock helper.

The actual release notes live on a work-in-progress preview page outside the changelog.
What the feed does show is a project running a disciplined pre-release: a rolling RC tag so testers do not have to chase point versions, and two-to-seven day turnarounds between candidates as bugs come in. What it does not show is a single feature, which means anyone tracking Immich through its changelog learns only that a major version is close, not what it changes.
A v3.0.0 stable release follows once the RC turnaround lengthens; the entries give no basis for predicting what it contains, because none of them describe it.

The stable line's last two releases were three GHSA security fixes and a UserManager lock helper.
Renumbering is the visible end of a decision made about the API — the project no longer expects the clean break that 10.x was holding a slot for, so the version number stops reserving one. Meanwhile 10.11.x is in wind-down posture, taking security backports and concurrency fixes rather than features, which is where the 12.0 work has clearly gone. The RC bodies themselves carry no feature detail, pointing at the forums instead.
Expect 12.0 to reach stable after the RC turnaround lengthens, with 10.11.x limited to security backports from that point; the entries do not say what 12.0 contains.
