Nextcloud vs SOGo: at a glance
What is Nextcloud?
Nextcloud ships three patch lines in a day as 35.0.2 adds webhook metadata and a report API.
Nextcloud released 35.0.2, 34.0.5 and 33.0.10 on the same day, a month after the 35.0.0 major that swapped OnlyOffice for Euro-Office and added FrankenPHP support. The backports share a security-flavored core: a CSRF token on the share-accept endpoint, upload checks against session and share tokens, and logs that no longer leak sensitive data. 35.0.2 also adds richer node-webhook metadata, webhook-compatible comment events and an API for system-report sections.
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.

Nextcloud ships three patch lines in a day as 35.0.2 adds webhook metadata and a report API.
◆ Current state
Nextcloud released 35.0.2, 34.0.5 and 33.0.10 on the same day, a month after the 35.0.0 major that swapped OnlyOffice for Euro-Office and added FrankenPHP support. The backports share a security-flavored core: a CSRF token on the share-accept endpoint, upload checks against session and share tokens, and logs that no longer leak sensitive data. 35.0.2 also adds richer node-webhook metadata, webhook-compatible comment events and an API for system-report sections.
◆ Where it's heading
The patch stream is still dominated by sharing permissions, resharer caps and encryption cache fixes, now applied across three supported branches at once. The small additions in 35.0.2, webhooks and the 'Unified Sharing Legacy Sync' groundwork, point to sharing being rebuilt under the hood and to more automation hooks for integrators. The 35 line is absorbing regressions from the major at a steady monthly pace.
◆ Prediction
Expect a 35.0.3 within a month continuing sharing and encryption fixes, with more of the unified-sharing work surfacing; the entries do not say when that rework becomes user-visible.
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.
