Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
The R side of Quarto stopped being a render wrapper and became a project interface
The quarto R package gives R users programmatic access to the Quarto CLI, and its 1.4 release is where that access stopped being a thin call to quarto render. Project creation, extension installation, template use, environment diagnostics and a vignette engine all arrived together, and 1.5.0 followed by changing how output paths are communicated to the CLI — through Quarto metadata rather than a command-line flag.

Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.

The package's job is to stay a faithful surface over a CLI it does not control, and the releases show what that costs. Version numbers track the Quarto release they target, tests are adapted around upstream regressions, and behaviour is reworked when the CLI changes — quarto_use_template() now errors clearly in non-empty directories because interactive prompting was never suitable for programmatic use. The 1.5.1 release exists entirely so CRAN checks pass on machines where Quarto is not installed at all.
Expect the next release to track the next Quarto CLI version, with the open question in the feed being how --no-prompt behaviour settles upstream for template use. Feature work here follows the CLI rather than leading it.
