Mattermost vs Pydio Cells: at a glance
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.
What is Pydio Cells?
Cells 5.1 gives tag values their own access policies, and 5.1.1 makes them hold up.
v5.1.0 added access policies for Entity Values, the metadata store v5 introduced, with dedicated CRUD endpoints and an admin flag that stops end users adding new tag values. v5.1.1 follows five weeks later with fixes for that same feature: the restrict-values toggle on TagCloud now switches off, and policy-group caching is safe under concurrent access. The 4.4 branch still gets occasional maintenance releases alongside v5.

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.
Pydio Cells
5.0COLLAB
Cells 5.1 gives tag values their own access policies, and 5.1.1 makes them hold up.
◆ Current state
v5.1.0 added access policies for Entity Values, the metadata store v5 introduced, with dedicated CRUD endpoints and an admin flag that stops end users adding new tag values. v5.1.1 follows five weeks later with fixes for that same feature: the restrict-values toggle on TagCloud now switches off, and policy-group caching is safe under concurrent access. The 4.4 branch still gets occasional maintenance releases alongside v5.
◆ Where it's heading
The v5 line has moved from post-launch stabilisation to filling out its metadata and permissions model, and each feature release is followed by a hardening pass on the same code. The releases point toward admins getting finer control over metadata, not toward new end-user features.
◆ Prediction
Expect more 5.1.x patches on policy and metadata performance before a 5.2 adds the next admin control. The entries do not show when the 4.4 branch will stop getting maintenance releases.
