What is AFFiNE?

AFFiNE's canaries add managed AI model routing, with OpenRouter support for self-hosters.

AFFiNE's November 10 canaries rework its server-side Copilot: managed model routing with route choices and defaults, OpenRouter and more request formats, and route options for self-hosted deployments, while cloud deployments can no longer set provider profiles. A follow-up resizes images to WebP for AI chats and reports images that fail to load instead of dropping them. Earlier November canaries fixed CalDAV setup and item ordering.

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.

AFFiNE vs Mattermost: editorial side-by-side

A
AFFiNE
COLLAB
5.0

AFFiNE's canaries add managed AI model routing, with OpenRouter support for self-hosters.

◆ Current state

AFFiNE's November 10 canaries rework its server-side Copilot: managed model routing with route choices and defaults, OpenRouter and more request formats, and route options for self-hosted deployments, while cloud deployments can no longer set provider profiles. A follow-up resizes images to WebP for AI chats and reports images that fail to load instead of dropping them. Earlier November canaries fixed CalDAV setup and item ordering.

◆ Where it's heading

After weeks of fixes and dependency bumps, the AI assistant is getting structural work: which model handles a request is becoming configurable, especially for self-hosters. Cloud and self-hosted setups are diverging in how much of that they control.

◆ Prediction

Expect more Copilot routing and error-handling fixes in the coming canaries; whether a stable release follows is not clear from the entries.

M6.3

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.
