What is evaluate?

The engine under every knitted R document reached 1.0 by making evaluation behave like the console.

evaluate captures the output, plots, messages and conditions produced by running R code, and it is the layer knitr and R Markdown sit on. The 1.0.0 release changed core semantics — multi-expression input now stops at the first error — and gave results a real class. Since then, releases have been graphics-focused: ragg-based capture when available, grid plot fixes, and a patch for ggplot2 4.0.0.

What is Resend?

Resend is wiring itself into every agent runtime it can reach, one standard at a time

Almost every recent entry is 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 now support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor — but it is the smaller half of the feed. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

0.0

The engine under every knitted R document reached 1.0 by making evaluation behave like the console.

◆ Current state

evaluate captures the output, plots, messages and conditions produced by running R code, and it is the layer knitr and R Markdown sit on. The 1.0.0 release changed core semantics — multi-expression input now stops at the first error — and gave results a real class. Since then, releases have been graphics-focused: ragg-based capture when available, grid plot fixes, and a patch for ggplot2 4.0.0.

◆ Where it's heading

The package is being tightened rather than expanded. 1.0.0 removed complexity it could not justify, deprecated include_timing, dropped a function testing for an object it never created, and aligned error behaviour with the console; 1.0.4 then moved plot capture toward a faster, more capable device. The recurring theme is reliability of output capture across environments, which is exactly what a document-rendering substrate needs and what local_reproducible_output() exists to enforce.

◆ Prediction

Expect continued fast-follow patches keyed to graphics-stack releases — ggplot2 and ragg in particular — rather than new API surface.

Resend is wiring itself into every agent runtime it can reach, one standard at a time

◆ Current state

Almost every recent entry is 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 now support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor — but it is the smaller half of the feed. 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: first authenticate third parties (OAuth), then be callable (MCP), then be installable per vendor (Codex, Claude), and now be installable by standard. The developer-experience work — secret scanning, email-client compatibility warnings, Message-ID threading — keeps the human-facing product credible while that shift happens.

◆ Prediction

Having covered authorization and discovery, the gap left is what an agent is permitted to send once connected; scoped, per-agent sending limits or approval controls are the natural next piece.
