What is SOGo?
SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.
SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.
What is Tango?
Tango's 2026 releases stay on workflow guides, capped by a rebrand and basic editor shortcuts.
Tango captures browser workflows into step-by-step guides, and its 2026 releases deepened that core: voice narration during capture, branching for different paths, translations, video embeds and Enterprise governance. The latest entries are a September rebrand with new fonts and colors and undo/redo shortcuts in edit mode. The AI CRM Admin browser agent launched in April 2025 has had no follow-up in the feed since.
SOGo vs Tango: editorial side-by-side
SOGo
2.5COLLAB
SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.
◆ Current state
SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.
◆ Where it's heading
Fixes are increasingly arriving with secure defaults that break lax configurations, first password recovery URLs and then LDAP certificate checks. Feature work has been absent since 5.12.4 a year ago.
◆ Prediction
Further 5.12.x security releases are likely; operators should expect more defaults that require configuration changes.
Tango
0.0COLLAB
Tango's 2026 releases stay on workflow guides, capped by a rebrand and basic editor shortcuts.
◆ Current state
Tango captures browser workflows into step-by-step guides, and its 2026 releases deepened that core: voice narration during capture, branching for different paths, translations, video embeds and Enterprise governance. The latest entries are a September rebrand with new fonts and colors and undo/redo shortcuts in edit mode. The AI CRM Admin browser agent launched in April 2025 has had no follow-up in the feed since.
◆ Where it's heading
The documentation product gets steady depth features while the AI agent bet has gone quiet in the changelog. The rebrand suggests a repositioning, but the entry does not say toward what.
◆ Prediction
It is unclear from the entries whether the rebrand signals a renewed AI agent push or a refocus on documentation; the next feature release should show which.
