What is Mattermost?

Every v11 release pushes ABAC further out; the blog sells the air-gap story around it.

Mattermost ships a v11.x release roughly monthly, and each one extends attribute-based access control another layer: v11.9 reached channel-level policies and ranked attributes, v11.10 adds team-level ABAC membership and native user attributes. Between releases the feed is marketing content aimed at defense, federal, and other air-gapped buyers. The product work and the publishing calendar are pulling in the same direction.

What is Trilium Notes?

A local-first note app hardens its imports and keeps AI optional

Trilium, now maintained as the TriliumNext community fork, is a local-first hierarchical note application on a steady monthly point-release cadence. Recent work centers on import fidelity, note-type expansion (spreadsheets and OCR in 0.103), security patches, and a pragmatic LLM stance: it removed bundled LLM integration in 0.102.0, then reintroduced a lighter, provider-backed model selector.

Mattermost vs Trilium Notes: editorial side-by-side

M5.0

Every v11 release pushes ABAC further out; the blog sells the air-gap story around it.

◆ Current state

Mattermost ships a v11.x release roughly monthly, and each one extends attribute-based access control another layer: v11.9 reached channel-level policies and ranked attributes, v11.10 adds team-level ABAC membership and native user attributes. Between releases the feed is marketing content aimed at defense, federal, and other air-gapped buyers. The product work and the publishing calendar are pulling in the same direction.

◆ Where it's heading

ABAC is being built out as the organizing primitive — first channels, now teams, with user attributes moving from an integration concern into the platform itself. The surrounding posts on agentic AI in disconnected environments read as demand-shaping for the AI features shipping in the same releases. Expect the two lines to converge on running agents inside a network that cannot call out.

◆ Prediction

The next v11 release should extend ABAC to a further scope or add policy administration tooling, and the agent features will keep being framed around operating without external model APIs.

T5.0

A local-first note app hardens its imports and keeps AI optional

◆ Current state

Trilium, now maintained as the TriliumNext community fork, is a local-first hierarchical note application on a steady monthly point-release cadence. Recent work centers on import fidelity, note-type expansion (spreadsheets and OCR in 0.103), security patches, and a pragmatic LLM stance: it removed bundled LLM integration in 0.102.0, then reintroduced a lighter, provider-backed model selector.

◆ Where it's heading

The fork is stabilizing and broadening ingest and interop — robust OneNote migration with device-code web authentication and multi-hour token refresh — while keeping AI optional and provider-driven rather than baked in. The direction is a dependable self-hosted knowledge base that reclaims data locked in other tools.

◆ Prediction

Expect continued import and format-fidelity work plus incremental, provider-dynamic LLM options rather than a bundled AI push; official mobile and multi-user remain community-demand items gated on funding.
