Read the Docs vs SOGo: at a glance
What is Read the Docs?
Read the Docs moves builds to Python 3.14 and Ubuntu 26.04 by default.
Read the Docs ships a dated release most weeks. October's notable changes: the default build image moved to Python 3.14 and Ubuntu 26.04, git:// URLs are no longer allowed, search scores pages by their best-matching section, and certifi was upgraded to distrust the compromised eMudhra CAs. Earlier October work added temporary environment variables in build commands, a size cap on build media, and the GitHub App as the default on Community.
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.

Read the Docs
5.0COLLAB
Read the Docs moves builds to Python 3.14 and Ubuntu 26.04 by default.
◆ Current state
Read the Docs ships a dated release most weeks. October's notable changes: the default build image moved to Python 3.14 and Ubuntu 26.04, git:// URLs are no longer allowed, search scores pages by their best-matching section, and certifi was upgraded to distrust the compromised eMudhra CAs. Earlier October work added temporary environment variables in build commands, a size cap on build media, and the GitHub App as the default on Community.
◆ Where it's heading
Two threads run through the releases: a direct upload path for docs built elsewhere, which has had design docs, workflows and onboarding in September and October, and steady hardening of the build platform. Most entries are still lists of merged PRs with dependency bumps.
◆ Prediction
Expect direct upload to move toward general availability and more GitHub App defaults replacing the OAuth app.
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.
