Slack
Slack is quietly rebuilding itself as a runtime for third-party agents.
A side-by-side editorial comparison of Happeo and BookStack — release velocity, themes, recent moves, and the top alternatives to consider.
Happeo's tracked feed is its intranet-SEO blog, not a product changelog.
Happeo's crawled feed is its content-marketing blog — intranet, enterprise-search, and knowledge-management explainers plus competitor-comparison pages (vs Notion, vs LumApps). These are SEO and positioning pieces, not shipped product changes, so no product trajectory can be read from this source.
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 feed will keep producing knowledge-management and intranet thought-leadership and comparison content, leaning on AI-search framing. Product moves are not observable here.
Tracking Happeo's actual releases would require a product-update feed; the blog will continue publishing search and knowledge-management marketing content.

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.
