What is Lidarr?

Lidarr 3.1 maintains a steady patch cadence with targeted bug fixes and no significant new features in the last six months.

Lidarr is shipping maintenance releases approximately every four to six weeks on the 3.1 branch. Each release contains a small number of targeted fixes — missing album search disablement, manual import release group correction, Spotify lookup rate limiting. The project is in a stable maintenance phase with no announced new capabilities.

What is Mattermost?

Mattermost v11.11 adds data spillage exposure tracking as v12.0 breaking changes loom

Mattermost is a self-hosted, air-gap-capable team communications platform with a clear focus on defense, government, and critical infrastructure. The v11.11 release adds a post exposure radius report that lets compliance reviewers quickly see who may have accessed a flagged message. Recent releases have extended ABAC governance to team-level membership with native user attributes, removing the integration overhead previously required for attribute-based policy control.

5.0

Lidarr 3.1 maintains a steady patch cadence with targeted bug fixes and no significant new features in the last six months.

◆ Current state

Lidarr is shipping maintenance releases approximately every four to six weeks on the 3.1 branch. Each release contains a small number of targeted fixes — missing album search disablement, manual import release group correction, Spotify lookup rate limiting. The project is in a stable maintenance phase with no announced new capabilities.

◆ Where it's heading

The release pattern over the last ten months shows consistent maintenance without any feature releases or minor version bumps beyond 3.1.0 to 3.1.5. Spotify API rate limit handling (3.1.3) and indexer bug fixes are the substantive improvements; the project is in steady-state for its core use case as an automated music collection manager.

◆ Prediction

The next likely move is a 3.2.x feature release — the 3.1 branch has been stable long enough to expect a new development cycle — but none is signaled in these entries. Rate limit improvements for additional music metadata APIs are the most likely incremental additions.

M5.0

Mattermost v11.11 adds data spillage exposure tracking as v12.0 breaking changes loom

◆ Current state

Mattermost is a self-hosted, air-gap-capable team communications platform with a clear focus on defense, government, and critical infrastructure. The v11.11 release adds a post exposure radius report that lets compliance reviewers quickly see who may have accessed a flagged message. Recent releases have extended ABAC governance to team-level membership with native user attributes, removing the integration overhead previously required for attribute-based policy control.

◆ Where it's heading

The product is building toward a full-stack governance and AI audit layer for regulated operators. v12.0 (October 2026) carries a significant deprecation load—RHEL 7/8 drop, glibc baseline bump, plugin breaking changes—signaling a platform modernization cycle. Alongside the product work, a sustained thought leadership push on Zero Trust maturity, sovereign AI, and agentic AI in air-gapped environments is positioning Mattermost directly against cloud-hosted collaboration tools in classified environments.

◆ Prediction

v12.0 will consolidate the recent ABAC and AI agent audit capabilities into a more integrated governance surface; self-hosted operators on RHEL 7/8 need to begin their infrastructure migration now to stay on the supported path.
