SOGo vs Jellyfin
A side-by-side editorial comparison of SOGo and Jellyfin — release velocity, themes, recent moves, and the top alternatives to consider.
SOGo vs Jellyfin: at a glance
What is SOGo?
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.
What is Jellyfin?
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.

SOGo
0.0COLLAB
SOGo's 5.12 line has become a CVE conveyor belt while the team's attention sits on SOGo 6.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
Expect the 5.12.x line to keep producing security releases with regression follow-ups, and no new functionality until SOGo 6 surfaces.
Jellyfin
2.5COLLAB
Jellyfin drops the 10. prefix and puts 12.0 through a three-candidate preview.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
