Slack is quietly rebuilding itself as a runtime for third-party agents.
A side-by-side editorial comparison of Rocket.Chat and BookStack — release velocity, themes, recent moves, and the top alternatives to consider.
Rocket.Chat grinds through 8.5/8.6 release candidates with security and federation work underneath
Rocket.Chat's feed is a stream of 8.5.x and 8.6.x release candidates, most of which are routine meteor version bumps and dependency updates. The substance sits in the .rc.0 cuts, where the real minor changes land: a unified presence engine foundation, attribute-based access control (ABAC) work, and an OAuth security overhaul.
Security-first wiki on a steady cadence; v26.05 lands the year's biggest feature batch
BookStack is a mature self-hosted wiki shipping on a near-monthly cadence dominated by security releases. The recent arc pairs a substantial v26.05 feature drop with a steady stream of patch releases hardening URL filtering, attachments, MFA, and permission checks. The project's priority is clearly locking down untrusted-editor and public-instance scenarios while keeping the feature surface moving.

The substance sits in the .rc.0 cuts, where the real minor changes land: a unified presence engine foundation, attribute-based access control (ABAC) work, and an OAuth security overhaul.
Two themes dominate the meaningful entries: enterprise access control (ABAC with a pluggable attribute store, new admin permissions) and authentication hardening (phishing-resistant MFA, server-side OAuth). Alongside that, federation reliability is being patched. This is a platform deepening its enterprise and self-hosted security posture rather than chasing new user-facing features.
Expect 8.6.0 to ship the unified presence engine and Virtru-backed ABAC out of RC, with continued federation sync fixes following the message-sync repair work flagged in 8.6.0-rc.1.

The project's priority is clearly locking down untrusted-editor and public-instance scenarios while keeping the feature surface moving.
The pattern is a feature-anchor release (v26.03, v26.05) followed by a run of point releases that are almost entirely security and dependency hardening. Feature work is trending toward finer-grained permissions (separate revision-view control), a broader API (tag browsing), and export/editor polish. Expect the same rhythm to continue: one meaty minor, then hardening.
The next release is likely another security/dependency point release (v26.05.3 or similar) continuing the attachment/URL-filtering hardening, with the following feature minor extending the API and permission model.
