What is Knock?

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.

What is waldo?

waldo keeps shedding dependencies while teaching its diff engine new object systems

waldo produces the object comparisons that testthat failure messages are built from. The recent releases do two things: drop dependencies - tibble, rematch2 and fansi have all gone - and extend comparison to object systems that did not exist when it was written, notably S7. Correctness of missing-value and tolerance semantics accounts for most of the rest.

Knock is pulling every customer-data source into notifications, then putting an agent on top.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

waldo keeps shedding dependencies while teaching its diff engine new object systems

◆ Current state

waldo produces the object comparisons that testthat failure messages are built from. The recent releases do two things: drop dependencies - tibble, rematch2 and fansi have all gone - and extend comparison to object systems that did not exist when it was written, notably S7. Correctness of missing-value and tolerance semantics accounts for most of the rest.

◆ Where it's heading

This is a package deliberately shrinking its footprint while widening what it understands. Since it is imported by testthat, every dependency it drops is one fewer package in the check environment of most of CRAN, which is clearly the motivation. The comparison logic itself changes only when R gains a new way to represent objects.

◆ Prediction

Expect S7 support to deepen from basic to complete as S7 adoption grows, and further dependency removals; the diff algorithm itself looks settled.
