Docspell vs Mattermost: at a glance
What is Docspell?
Docspell's tagged releases stopped in 2025; the upload API only moves on the nightly.
No numbered release has landed since 0.43.0, which was itself a fixes-and-dependencies close-out. Work continues on the rolling nightly tag, where the current build adds optional priority to upload metadata, returns file keys and job ids from the upload API, and exposes a secured endpoint to fetch a file by key. That is real API surface, but it reaches only users willing to run nightly builds.
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.

Docspell's tagged releases stopped in 2025; the upload API only moves on the nightly.
◆ Current state
No numbered release has landed since 0.43.0, which was itself a fixes-and-dependencies close-out. Work continues on the rolling nightly tag, where the current build adds optional priority to upload metadata, returns file keys and job ids from the upload API, and exposes a secured endpoint to fetch a file by key. That is real API surface, but it reaches only users willing to run nightly builds.
◆ Where it's heading
The project is drifting toward nightly-only distribution: contributors keep landing work, maintainers keep not cutting tags. The newest additions cluster on programmatic ingestion — a caller submitting a document, then retrieving it by key — which points at Docspell being shaped as a component other systems feed rather than a standalone archive.
◆ Prediction
The upload-API work in #3338 is the most likely core of a next tagged release if one is cut. Whether the tagged line resumes at all is not readable from these notes.
Mattermost

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.
