What is Knock?
Knock keeps absorbing customer data sources, puts an agent on top, and now aims at internal alerts.
The recent window splits into three strands: data sources (Clay, Amplitude) that remove the sync layer customers normally write between product data and messaging; workflow primitives (wait-for-event, branch rebasing) that make notification sequences behave like state machines; and an agent that reads the resulting message data in plain language. The newest addition points somewhere else — connecting a team's own Slack workspace to send to internal channels and recipients rather than to end users.
What is packrat?
R's old dependency manager now runs on a vendored copy of its own successor.
packrat was R's project dependency manager before renv replaced it, and its recent releases describe a package in careful retirement. It vendors renv internally and uses it for dependency detection and authenticated downloads, so several release notes amount to updating that bundled copy. The remaining work is repository plumbing: recognising Bioconductor packages that now carry a Repository field, handling CRAN-like, Nexus and older Artifactory archive layouts, and renaming downloads from r-universe that do not follow the expected filename pattern.

Knock
6.3INFRA · APIS
Knock keeps absorbing customer data sources, puts an agent on top, and now aims at internal alerts.
◆ Current state
The recent window splits into three strands: data sources (Clay, Amplitude) that remove the sync layer customers normally write between product data and messaging; workflow primitives (wait-for-event, branch rebasing) that make notification sequences behave like state machines; and an agent that reads the resulting message data in plain language. The newest addition points somewhere else — connecting a team's own Slack workspace to send to internal channels and recipients rather than to end users.
◆ Where it's heading
The pattern is consistent: whatever a customer would otherwise build around Knock, Knock absorbs. Sync code became data sources, report building became the agent, and internal alerting — usually a separate webhook or a homegrown Slack app — becomes another recipient type. The management surfaces landing alongside it (categories, tags, saved views) are the housekeeping that accumulation forces.
◆ Prediction
More internal-destination work is the likely next step, extending the same use case beyond Slack, alongside further data sources following the Clay and Amplitude pattern.
packrat
0.0INFRA · APIS
R's old dependency manager now runs on a vendored copy of its own successor.
◆ Current state
packrat was R's project dependency manager before renv replaced it, and its recent releases describe a package in careful retirement. It vendors renv internally and uses it for dependency detection and authenticated downloads, so several release notes amount to updating that bundled copy. The remaining work is repository plumbing: recognising Bioconductor packages that now carry a Repository field, handling CRAN-like, Nexus and older Artifactory archive layouts, and renaming downloads from r-universe that do not follow the expected filename pattern.
◆ Where it's heading
Development here is about keeping existing projects restorable rather than making packrat a better choice for new ones. Nearly every entry is a fix for an environment that changed underneath it — a repository layout, a service's authentication scheme, a distribution's URL format. The vendoring of renv is the clearest statement of direction: the successor's logic is doing the work, wrapped in the old interface.
◆ Prediction
Expect further releases only when package repositories change shape or the vendored renv needs refreshing, at roughly the two-year cadence the recent history shows. Nothing suggests new capability, and the practical migration path remains renv itself.
