ownCloud vs Mattermost: at a glance
What is ownCloud?
After years on the 10.x maintenance line, ownCloud Classic is finally cutting 11.0.0 candidates
Two tracks run side by side. The 10.16.x line continues as maintenance, with 10.16.4 published as a security release and upgrade strongly recommended for all installations. In parallel, ownCloud Server 11.0.0 has reached its third release candidate, with rc2 and rc3 consisting of version-string bumps and no code change.
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.

◆ Current state
Two tracks run side by side. The 10.16.x line continues as maintenance, with 10.16.4 published as a security release and upgrade strongly recommended for all installations. In parallel, ownCloud Server 11.0.0 has reached its third release candidate, with rc2 and rc3 consisting of version-string bumps and no code change.
◆ Where it's heading
The interesting movement is the 11.0.0 candidate train — the first major-version step for Classic after a long run of 10.x point releases. The release notes attached to the candidates say nothing about capability, so what 11.0.0 actually changes for administrators is not yet visible here; the tags only show it converging.
◆ Prediction
A general 11.0.0 release is the obvious next step once the candidate train stops iterating, with the 10.16.x line likely continuing to receive security backports alongside it.
Mattermost

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.
