Lidarr vs Mattermost: at a glance
What is Lidarr?
Lidarr's 3.2 pre-release fixes Jellyfin 12 connections and stops logging Postgres passwords.
Lidarr ships small maintenance releases every few weeks. The stable 3.1.6 improved Allowed Hosts and Trusted Networks handling and added release year detection. On develop, 3.2.0 added wildcard IPs and cache cleanup, and 3.2.1 now fixes connections to Jellyfin 12+, stops the Postgres password appearing in migration logs and uses Happy Eyeballs for HTTP connections.
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.
Lidarr vs Mattermost: editorial side-by-side
Lidarr
5.0COLLAB
Lidarr's 3.2 pre-release fixes Jellyfin 12 connections and stops logging Postgres passwords.
◆ Current state
Lidarr ships small maintenance releases every few weeks. The stable 3.1.6 improved Allowed Hosts and Trusted Networks handling and added release year detection. On develop, 3.2.0 added wildcard IPs and cache cleanup, and 3.2.1 now fixes connections to Jellyfin 12+, stops the Postgres password appearing in migration logs and uses Happy Eyeballs for HTTP connections.
◆ Where it's heading
The 3.2 line follows the shared *arr pattern: networking and security fixes that land across Radarr, Prowlarr and Lidarr at once, plus app-specific fixes for media servers and imports. Nothing here changes what Lidarr does.
◆ Prediction
A stable 3.2 release is the likely next step, following the pre-release-then-stable cadence of 3.1.6.
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.
