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 Miniflux?

A minimal RSS reader that made passkeys the only way in, then went back to polishing the reading experience.

Miniflux ships a release roughly monthly, and the 2.2.19-through-2.3.1 stretch was almost entirely security work: OIDC token signature verification, PKCE state cleanup, SHA1 replaced with HMAC-SHA256 for Google Reader API auth, an OAuth account-binding vulnerability, an open redirect, and a possible SQL injection in dynamically built ORDER BY clauses. The two most recent releases return to product — full-text search on PostgreSQL's websearch_to_tsquery, an expanded API v1, and feed language detection.

Mattermost vs Miniflux: 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.

2.5

A minimal RSS reader that made passkeys the only way in, then went back to polishing the reading experience.

◆ Current state

Miniflux ships a release roughly monthly, and the 2.2.19-through-2.3.1 stretch was almost entirely security work: OIDC token signature verification, PKCE state cleanup, SHA1 replaced with HMAC-SHA256 for Google Reader API auth, an OAuth account-binding vulnerability, an open redirect, and a possible SQL injection in dynamically built ORDER BY clauses. The two most recent releases return to product — full-text search on PostgreSQL's websearch_to_tsquery, an expanded API v1, and feed language detection.

◆ Where it's heading

Two threads run in parallel. The security thread has systematically closed off every authentication path that was not cryptographically strict, culminating in 2.3.0 restricting WebAuthn login to discoverable passkeys only. The product thread is API-shaped: entry ID pagination, bulk starred updates, tag filtering, and a Go client that now exposes the full feed record — all aimed at people driving Miniflux from other software rather than its own UI.

◆ Prediction

The API surface is the area with visible momentum, so the next release most likely extends filtering or bulk operations further. Whether the passkey-only stance loosens to accommodate post-password MFA is the open question these notes raise but do not answer.
