highr is finished software: one-line releases every year or two
highr does syntax highlighting for knitr output, and every release in this window is a single line of change. The most recent wraps hilight() output in xfun::raw_string() for nicer printing; before that, a rename of two LaTeX command macros and two bumps to the minimum R version. There is no feature work here at all.
Knock is pulling every customer-data source into notifications, then putting an agent on top.
Knock is a notification infrastructure layer, and the last two months have gone into two things: widening what can trigger a workflow, and making the resulting data legible. Amplitude and Clay both landed as first-class data sources, so product events, cohort changes and enriched CRM rows now drive messaging directly rather than through customer-written glue. The workflow engine gained a wait-for-event primitive, and the template editor was rebuilt around block editing.

This is a completed micro-package in the knitr ecosystem, maintained only to stay installable and consistent with its parent packages. Changes are triggered by knitr's needs or CRAN's requirements rather than by any plan of its own, and the gaps between releases run to years.
Expect the next release whenever knitr or CRAN requires one, with a similarly single-line changelog.

The shape is a product moving up from delivery mechanics toward the surrounding workflow. Sources reduce the integration code a customer writes before Knock is useful; the agent layer reduces the reporting work after. Category and tag management being pulled into dedicated dashboard pages is the housekeeping that follows: the primitives got numerous enough to need their own administration surface.
Expect the data-source list to keep growing along the same lines — warehouse and product-analytics tools that already hold the user state Knock needs — and for the agent to be given more of the dashboard's read surface.
