FreshRSS vs Mattermost: at a glance
What is FreshRSS?
FreshRSS ships two security releases in a day for PHP CVEs and moves Docker to Debian 13.
FreshRSS has issued four 1.30.x security releases since the 1.30.0 change that blocked local network access by default. 1.30.3 and 1.30.4, both on Oct 21, patched severe PHP vulnerabilities in the official Docker images: Debian first, now on Debian 13 Trixie, then Alpine. The project points users who want faster patches to its rolling edge channel.
What is Mattermost?
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.

FreshRSS
5.0COLLAB
FreshRSS ships two security releases in a day for PHP CVEs and moves Docker to Debian 13.
◆ Current state
FreshRSS has issued four 1.30.x security releases since the 1.30.0 change that blocked local network access by default. 1.30.3 and 1.30.4, both on Oct 21, patched severe PHP vulnerabilities in the official Docker images: Debian first, now on Debian 13 Trixie, then Alpine. The project points users who want faster patches to its rolling edge channel.
◆ Where it's heading
The 1.30 line has become a security maintenance branch, and new features wait for the next major. The team is treating its Docker images as part of the product it must patch, not just the PHP code.
◆ Prediction
More 1.30.x point releases are likely as upstream PHP and base-image fixes land; new features probably arrive with 1.31.
Mattermost
6.3COLLAB
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
◆ Current state
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
◆ Where it's heading
Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.
◆ Prediction
Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.
