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.

What is AFFiNE?

AFFiNE ships stable iOS Share Extension imports while patching editor correctness and selfhost deployment

AFFiNE is releasing daily canary builds that advance the iOS client (Share Extension now stable, share-to-support in prior weeks) alongside editor reliability fixes — heading preservation in readonly mode and priority queue correctness in the block editor. Selfhost deployment is also receiving correctness fixes, indicating the self-hosted user base is growing.

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.

AFFiNE ships stable iOS Share Extension imports while patching editor correctness and selfhost deployment

◆ Current state

AFFiNE is releasing daily canary builds that advance the iOS client (Share Extension now stable, share-to-support in prior weeks) alongside editor reliability fixes — heading preservation in readonly mode and priority queue correctness in the block editor. Selfhost deployment is also receiving correctness fixes, indicating the self-hosted user base is growing.

◆ Where it's heading

The consistent mobile investment suggests AFFiNE is treating iOS as a primary platform, not a secondary one. The canary cadence will harden into stable releases as mobile features reach parity; the selfhost fixes indicate a parallel push toward enterprise self-deployment alongside the consumer cloud offering.

◆ Prediction

The next stable release will consolidate iOS Share Extension improvements; given the concurrent account-switching work, a meaningful update to multi-account or team collaboration workflows seems likely.
