Read the Docs vs SOGo
A side-by-side editorial comparison of Read the Docs and SOGo — release velocity, themes, recent moves, and the top alternatives to consider.
Read the Docs vs SOGo: at a glance
What is Read the Docs?
Read the Docs is rebuilding its build farm around uv and isolated builders, one week at a time.
Weekly date-tagged releases, almost entirely build infrastructure. The visible work is a migration to uv-managed environments and isolated, ephemeral builders, shipped in small increments between routine dependency bumps. The two most recent releases are the quietest of the run: plumbing for uv and build status in one, and a video extension bump, a nullable-field step toward dropping has_valid_clone, and Python 3.14 for the pip-tools workflow in the other.
What is SOGo?
SOGo's release notes have become a vulnerability disclosure channel with a version number attached.
SOGo is a self-hosted groupware suite — webmail, calendaring and contacts — maintained by Alinto. Four of the last six releases exist primarily to fix security vulnerabilities: XSS through malicious mail, SQL injection, OpenID impersonation, script execution via theme and hint query parameters. The newest, 5.12.10, fixes four more and states that all previous versions are affected, with CVE identifiers still pending at publication.

Read the Docs is rebuilding its build farm around uv and isolated builders, one week at a time.
◆ Current state
Weekly date-tagged releases, almost entirely build infrastructure. The visible work is a migration to uv-managed environments and isolated, ephemeral builders, shipped in small increments between routine dependency bumps. The two most recent releases are the quietest of the run: plumbing for uv and build status in one, and a video extension bump, a nullable-field step toward dropping has_valid_clone, and Python 3.14 for the pip-tools workflow in the other.
◆ Where it's heading
The isolated builder is the arc worth tracking — private repository support, an ephemeral builder script, and removal of the old scale-in protection path all point at builds that run in disposable environments. Alongside it runs a quieter cleanup pattern: fields are made nullable before removal, feature flags are deleted once the code behind them lands, and Python versions are pushed forward in the tooling before the runtime. User-facing change is rare and arrives as a side effect, as when July's release moved images to Ubuntu 26.04 and Python 3.14.
◆ Prediction
Expect the isolated builder to become the default path and further uv environment fixes; the has_valid_clone column being made nullable signals its removal in a following release. Feature work should stay secondary until that migration finishes.
SOGo
2.5COLLAB
SOGo's release notes have become a vulnerability disclosure channel with a version number attached.
◆ Current state
SOGo is a self-hosted groupware suite — webmail, calendaring and contacts — maintained by Alinto. Four of the last six releases exist primarily to fix security vulnerabilities: XSS through malicious mail, SQL injection, OpenID impersonation, script execution via theme and hint query parameters. The newest, 5.12.10, fixes four more and states that all previous versions are affected, with CVE identifiers still pending at publication.
◆ Where it's heading
The pattern is a codebase whose input-handling surface is being systematically probed, largely by the community reporting to the project's bug address, and patched in batches. Release numbering has stopped being reliable as a timeline — 5.12.7 shipped after 5.12.8 — so version order tells you nothing about what a deployment contains. The two non-security releases in this window were both regression repairs from the security releases that preceded them, which is the cost of shipping fixes at this cadence.
◆ Prediction
Given four security batches in five months and CVE identifiers still being assigned retroactively, another batch on the same cadence is the most likely next release, with a regression patch following it.
