Slack is quietly rebuilding itself as a runtime for third-party agents.
A side-by-side editorial comparison of Zoho Sign and BookStack — release velocity, themes, recent moves, and the top alternatives to consider.
Zoho Sign grinds out integrations and country-by-country compliance, no single leap
Zoho Sign is a mature e-signature product shipping a steady stream of concrete additions: a Microsoft SharePoint integration, signer identity verification via Didit and Stripe, and expanding legally-binding coverage market by market. The feed is a product blog, but most entries here document real, shipped features rather than pure marketing.
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 is a product blog, but most entries here document real, shipped features rather than pure marketing.
Two axes are widening in parallel: workflow depth (SharePoint sync, sandbox testing, delegated signing, recipient managers) and regional compliance (pan-India e-Stamping, Nafath in Saudi Arabia, Colombia, Kenya's certified-signature mandate). Zoho Sign is competing on breadth of jurisdictional coverage and integration surface rather than a headline capability.
Expect more national identity and e-stamping integrations as new markets tighten e-signature rules, plus continued workflow tooling in the vein of sandbox and delegated signing. The cadence is incremental and steady, not punctuated by big bets.

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.
