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.

What is Resend?

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

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.

6.3

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

◆ Current state

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

◆ Where it's heading

Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.

◆ Prediction

Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.
