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.
What is quarto-r?
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.

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.

The R side of Quarto stopped being a render wrapper and became a project interface
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
