A side-by-side editorial comparison of Immich and Zettlr — release velocity, themes, recent moves, and the top alternatives to consider.
Immich's 3.4 candidate adds passkeys and built-in backups.
Immich released v3.3 candidates in early October with people management, TensorRT-RTX acceleration, birthday memories and lighter ML models, and the first v3.4 candidate on 30 October. 3.4 rc.1 adds passkey sign-in, built-in backups using restic's parallel scan, JPEG XL decoding and encoding, mobile tags and workflow filters, plus a block of security fixes around shared links, partner timelines, symlinks and OAuth cookies.
Zettlr added admonitions after six years, then spent a release fixing its updater.
Zettlr 4.8.0 brought admonitions, a feature six years in the making, plus translation updates and a fix for a long-standing logic bug in search. 4.9.0 followed in late October to stop a false 'Update failed' error introduced by 4.8, drop macOS 12 and old Ubuntu support, distrust the eMudhra TLS certificates and render reference-style images.

Each minor now runs through three or four public candidates before release. The 3.x line moved from discovery features (search, faces, memories) toward running Immich safely as a household's primary photo store: sharing controls, authentication and backups.
v3.4.0 stable should follow after one or two more candidates. Restoring from the new backups inside Immich is the natural follow-up if it isn't already part of 3.4.

Releases arrive roughly monthly and alternate between a headline writing feature and cleanup of the previous one. The app is tracking Electron's platform support, so older operating systems will keep falling away.
A small 4.9.x fix release or a feature-led 4.10 in about a month fits the pattern; the entries don't hint at its contents.
