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 NGINX?

Mainline and stable now move in lockstep, and almost every move is a CVE.

NGINX is running 1.31.x mainline and 1.30.x stable in parallel, cutting matched pairs of releases minutes apart whenever a security fix lands. Every release in the window is security-driven: buffer overflows in map-with-regex and the rewrite module, memory disclosure in the slice module, use-after-free in SSI and HTTP/3, buffer overreads in charset, SCGI and uWSGI. Feature work is confined to what rides along — a SipHash-based request ID, an $ssl_sigalgs variable.

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.

5.0

Mainline and stable now move in lockstep, and almost every move is a CVE.

◆ Current state

NGINX is running 1.31.x mainline and 1.30.x stable in parallel, cutting matched pairs of releases minutes apart whenever a security fix lands. Every release in the window is security-driven: buffer overflows in map-with-regex and the rewrite module, memory disclosure in the slice module, use-after-free in SSI and HTTP/3, buffer overreads in charset, SCGI and uWSGI. Feature work is confined to what rides along — a SipHash-based request ID, an $ssl_sigalgs variable.

◆ Where it's heading

The 1.30.0 stable branch pulled in a substantial feature set from 1.29.x — Early Hints, HTTP/2 to backend, Encrypted ClientHello, sticky upstream sessions, Multipath TCP, HTTP/1.1 keep-alive as the proxy default — and 1.31.0 added HTTP forward proxy and least_time load balancing. Since those, the project has been consolidating: hardening the newer protocol modules, particularly HTTP/2 and HTTP/3, where most of the recent CVEs cluster.

◆ Prediction

Expect the paired mainline/stable security releases to continue at this cadence, with the vulnerability reports staying concentrated in HTTP/2, HTTP/3 and the proxying modules that 1.30 broadened.
