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 renv?
renv 1.2 made installs parallel, its biggest performance change in years.
renv provides project-local dependency management for R. The 1.2.0 release rebuilt installation to download and compile concurrently, and the 1.2.x line since has been resolving the correctness problems parallelism exposed — binaries installing ahead of their dependencies, transitive upgrades that were never needed, lockfile paths shifting with the working directory.

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.
renv
2.5INFRA · APIS
renv 1.2 made installs parallel, its biggest performance change in years.
◆ Current state
renv provides project-local dependency management for R. The 1.2.0 release rebuilt installation to download and compile concurrently, and the 1.2.x line since has been resolving the correctness problems parallelism exposed — binaries installing ahead of their dependencies, transitive upgrades that were never needed, lockfile paths shifting with the working directory.
◆ Where it's heading
Work is consolidating around two things: making the parallel installer correct under real dependency graphs, and broadening remote support so private and self-hosted sources resolve properly. The most recent release translates self-hosted GitLab remotes into the syntax pkgdepends actually understands.
◆ Prediction
Expect continued fixes to install ordering and remote resolution rather than another performance overhaul, since the parallel path is new enough to keep surfacing ordering bugs.
