Jellyfin
Jellyfin drops the 10. prefix and puts 12.0 through a three-candidate preview.
A side-by-side editorial comparison of SOGo and SiYuan — release velocity, themes, recent moves, and the top alternatives to consider.
SOGo's 5.12 line has become a CVE conveyor belt while the team's attention sits on SOGo 6.
Six releases in three months, and the majority exist to fix vulnerabilities: XSS via crafted mail, SQL injection, JavaScript injection through hint and theme query parameters, impersonation when OpenID is paired with a non-matching user source, and two CVEs affecting PostgreSQL user sources. Releases 5.12.6 and 5.12.9 exist purely to undo regressions the security fixes introduced.
Near-daily alphas grinding toward parity between desktop and every mobile OS
SiYuan tags alphas almost daily — six v3.7.4 alphas in nine days following the v3.7.3 stable on July 21. The notes are cumulative, so each alpha restates the previous list and appends what landed since, which makes the train look larger than it is. Individual entries are long lists of small enhancements rather than headline features.

Alinto declared a feature freeze on 5.12 to concentrate on SOGo 6, and the changelog reflects it — the one new capability in the window, a REST API in 5.12.2, was explicitly a pre-committed sponsored deliverable the team felt obliged to honour. What is left is a hardening cycle on a large groupware surface, with each fix carrying real regression risk into webmail and calendar.
Expect the 5.12.x line to keep producing security releases with regression follow-ups, and no new functionality until SOGo 6 surfaces.

Two threads dominate. The first is mobile and multi-OS parity: audio recording on Android and HarmonyOS, S Pen hover for block popovers on Android tablets, batch image insertion in the HarmonyOS editor, back-action dialog ordering, custom font import on mobile, and RPM packaging that coexists with other Electron apps. Treating HarmonyOS as a first-class target alongside Android and iOS is unusual for a note-taking tool this size. The second is the database feature set maturing into a structured-data layer — column alignment, relation backlinks in the attribute panel, item templates, and deep links to individual database items.
A v3.7.4 stable should follow within weeks given v3.7.3 shipped after three betas in as many days. Expect the database and HarmonyOS threads to keep accumulating small enhancements rather than a single large feature.
