Mattermost vs Radarr: 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 Radarr?
Radarr's 7.0 pre-release line now shows every audio and subtitle stream per file.
Radarr's 7.0 pre-release line is on its third build. 7.0.0 moved the app to .NET 10 and added OIDC login, PEM certificates and Trakt Smart List imports, and 7.0.1 lists every audio and subtitle stream per file. 7.0.2 adds Happy Eyeballs connection handling, custom ntfy headers, qBittorrent single-file imports from the root path, and stops logging the Postgres password during migration. The main branch is still on 6.4.4.

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.
Radarr
5.0COLLAB
Radarr's 7.0 pre-release line now shows every audio and subtitle stream per file.
◆ Current state
Radarr's 7.0 pre-release line is on its third build. 7.0.0 moved the app to .NET 10 and added OIDC login, PEM certificates and Trakt Smart List imports, and 7.0.1 lists every audio and subtitle stream per file. 7.0.2 adds Happy Eyeballs connection handling, custom ntfy headers, qBittorrent single-file imports from the root path, and stops logging the Postgres password during migration. The main branch is still on 6.4.4.
◆ Where it's heading
The 7.0 cycle pairs a platform upgrade with deeper file-level detail: media info, import diagnostics and download-client labels. The media info migration was split into batches to avoid running out of memory, which shows the team is hardening the upgrade path for large libraries before a stable release.
◆ Prediction
More 7.0.x pre-release builds with import and media info fixes are likely before 7.0 reaches the main branch; the entries do not show a date for that promotion.
