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 rsconnect?
The deployment client is being rebuilt around credentials it never has to store.
rsconnect is the publishing client for Posit Connect and shinyapps.io, and the last year has changed both ends of it. The HTTP layer moved to httr2 and the Connect API to v1; Posit Cloud publishing was removed outright and Posit Connect Cloud added in its place; and authentication picked up identity federation from Posit Workbench, Snowflake-hosted Connect with browser-based auth, and Snowflake connection names read from connections.toml. The most recent release fixes a regression that broke deployment entirely in air-gapped environments.

Knock

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.
rsconnect

The deployment client is being rebuilt around credentials it never has to store.
◆ Current state
rsconnect is the publishing client for Posit Connect and shinyapps.io, and the last year has changed both ends of it. The HTTP layer moved to httr2 and the Connect API to v1; Posit Cloud publishing was removed outright and Posit Connect Cloud added in its place; and authentication picked up identity federation from Posit Workbench, Snowflake-hosted Connect with browser-based auth, and Snowflake connection names read from connections.toml. The most recent release fixes a regression that broke deployment entirely in air-gapped environments.
◆ Where it's heading
Two threads run through this. The first is credential elimination — every recent auth change replaces a stored secret with a token the runtime can mint, whether that is Workbench identity federation or a Snowflake connection profile. The second is dependency capture getting stricter about what it actually needs: renv profiles outside the project root, pak-installed packages resolved against configured repositories, and Bioconductor contacted only when a Bioconductor package is genuinely present. Both are the problems you hit deploying inside a regulated network.
◆ Prediction
Expect the httr2 escape hatch option to be removed once the migration settles, and expect the mcp content category added in 1.10.1 to grow real configuration rather than staying an inferred default.
