What is Knock?
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
What is ZoneMinder?
1.38.4 is a security release in all but name, closing ACL gaps across the API.
The 1.38 line is in maintenance, and 1.38.4 is almost entirely authorization work: per-monitor access control enforced on event, frame, zone, tag and media endpoints, two auth bypasses fixed in token validation, and SQL injection and overflow hardening. The 1.36 branch still receives backports, with 1.36.38 carrying its own SQL injection fix. The last feature release was 1.38.0 in February, which brought role-based access control, WebRTC and Go2RTC streaming, and the split of monitor function into separate capturing, analysing, and recording settings.

Knock

Knock is hardening for enterprise buyers while its agent takes over the analysis work.
◆ Current state
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
◆ Where it's heading
Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
◆ Prediction
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.
ZoneMinder
2.5INFRA · APIS
1.38.4 is a security release in all but name, closing ACL gaps across the API.
◆ Current state
The 1.38 line is in maintenance, and 1.38.4 is almost entirely authorization work: per-monitor access control enforced on event, frame, zone, tag and media endpoints, two auth bypasses fixed in token validation, and SQL injection and overflow hardening. The 1.36 branch still receives backports, with 1.36.38 carrying its own SQL injection fix. The last feature release was 1.38.0 in February, which brought role-based access control, WebRTC and Go2RTC streaming, and the split of monitor function into separate capturing, analysing, and recording settings.
◆ Where it's heading
Every release since 1.38.0 has been consolidation of what that release opened up. RBAC shipped as a headline feature in February, and the four maintenance drops since have been finding the endpoints it did not cover — the familiar pattern when a permission model is retrofitted onto an API that predates it. Cadence is slow and irregular, months apart, with a 1.39 spec bump already visible in the repo but nothing from that series shipped.
◆ Prediction
Expect more per-endpoint ACL fixes on the 1.38 line before anything from 1.39 reaches release.
