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 YARA?
YARA ships bounds checks, not features — three patch releases published thirteen minutes apart.
Every release in this window is memory safety work on the parsers. The July batch bounds the rule table index in two opcodes, the tilde stream row count in the dotnet module and the repeat stack depth in the regex fiber sync, and fixes a leak in rule stream loading. Earlier releases closed a heap overflow triggered by hand-crafted compiled rules, infinite loops on corrupt PE resource directories, and an integer overflow in ELF parsing. The three most recent tags were published within thirteen minutes of each other.

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.
YARA
5.0INFRA · APIS
YARA ships bounds checks, not features — three patch releases published thirteen minutes apart.
◆ Current state
Every release in this window is memory safety work on the parsers. The July batch bounds the rule table index in two opcodes, the tilde stream row count in the dotnet module and the repeat stack depth in the regex fiber sync, and fixes a leak in rule stream loading. Earlier releases closed a heap overflow triggered by hand-crafted compiled rules, infinite loops on corrupt PE resource directories, and an integer overflow in ELF parsing. The three most recent tags were published within thirteen minutes of each other.
◆ Where it's heading
YARA is being maintained as an input parser under adversarial pressure rather than developed as a language. The last release to add anything — 4.5.0, with unreferenced string rules, strict escape warnings and a slow-rule callback — is nearly two years back, and everything since has been bounding a value someone found a way to overflow. Even the scan limit change was a revert to a prior default.
◆ Prediction
Expect the pattern to hold: batched patch releases whose contents are bounds checks in the PE, dotnet and regex paths, since that is where every recent finding has landed. Nothing in these entries suggests new language or module capability is queued.
