What is evaluate?
The engine under every knitted R document reached 1.0 by making evaluation behave like the console.
evaluate captures the output, plots, messages and conditions produced by running R code, and it is the layer knitr and R Markdown sit on. The 1.0.0 release changed core semantics — multi-expression input now stops at the first error — and gave results a real class. Since then, releases have been graphics-focused: ragg-based capture when available, grid plot fixes, and a patch for ggplot2 4.0.0.
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.

evaluate
0.0INFRA · APIS
The engine under every knitted R document reached 1.0 by making evaluation behave like the console.
◆ Current state
evaluate captures the output, plots, messages and conditions produced by running R code, and it is the layer knitr and R Markdown sit on. The 1.0.0 release changed core semantics — multi-expression input now stops at the first error — and gave results a real class. Since then, releases have been graphics-focused: ragg-based capture when available, grid plot fixes, and a patch for ggplot2 4.0.0.
◆ Where it's heading
The package is being tightened rather than expanded. 1.0.0 removed complexity it could not justify, deprecated include_timing, dropped a function testing for an object it never created, and aligned error behaviour with the console; 1.0.4 then moved plot capture toward a faster, more capable device. The recurring theme is reliability of output capture across environments, which is exactly what a document-rendering substrate needs and what local_reproducible_output() exists to enforce.
◆ Prediction
Expect continued fast-follow patches keyed to graphics-stack releases — ggplot2 and ragg in particular — rather than new API surface.
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.
