Slack is quietly rebuilding itself as a runtime for third-party agents.
A side-by-side editorial comparison of BookStack and Powell Software — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Powell's feed is mostly content marketing, punctuated by occasional 'What's new' release digests.
Powell Software's tracked feed is dominated by content marketing — digital-workplace guides, event recaps, and lead-gen tools — around its Microsoft 365 intranet product. The one product signal in the mix is a periodic 'What's new in Powell' release digest; the latest bundles a mobile-first experience, AI additions, and richer analytics.

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.

To the extent the feed shows product direction, it points at mobile-first intranet access, embedded AI, and storytelling analytics — the standard digital-workplace playbook. But most entries are marketing collateral, so cadence is hard to read from this source; the 'What's new' posts are the only reliable release signal.
The next genuine product signal will likely arrive as another 'What's new in Powell' digest continuing the mobile, AI, and analytics themes; the rest of the feed stays blog content.
