Paperless-ngx vs Mattermost: at a glance
What is Paperless-ngx?
Paperless-ngx follows its busy October with a fixes-only 3.4.2
Paperless-ngx ran from 3.3.0 to 3.4.1 in October, with two security releases and a 3.4.0 feature drop: custom fields in workflow title templates, relative-date queries, skipping local 2FA for trusted OIDC logins, poppler thumbnails and markdown in AI chat. 3.4.2 on 3 November is fixes and dependency updates, mostly mobile document-detail UX and Celery task handling.
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.

Paperless-ngx
5.0COLLAB
Paperless-ngx follows its busy October with a fixes-only 3.4.2
◆ Current state
Paperless-ngx ran from 3.3.0 to 3.4.1 in October, with two security releases and a 3.4.0 feature drop: custom fields in workflow title templates, relative-date queries, skipping local 2FA for trusted OIDC logins, poppler thumbnails and markdown in AI chat. 3.4.2 on 3 November is fixes and dependency updates, mostly mobile document-detail UX and Celery task handling.
◆ Where it's heading
The project is in a stabilization phase after 3.4.0, with patch releases every few days cleaning up UI regressions and dependencies. Feature work lands in minor releases roughly monthly.
◆ Prediction
More 3.4.x patches are likely before the next minor; the entries do not indicate what 3.5 will contain.
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.
