What is pkgload?

pkgload is quietly wiring R package development into modern IDE tooling.

pkgload implements load_all(), the function that simulates installing and loading a package during development, and sits directly underneath devtools. Recent releases pair correctness work on the reload path with integrations aimed at editors: compile_commands.json generation for LSP servers, and breakpoint injection in Positron.

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.

pkgload vs Resend: editorial side-by-side

pkgload is quietly wiring R package development into modern IDE tooling.

◆ Current state

pkgload implements load_all(), the function that simulates installing and loading a package during development, and sits directly underneath devtools. Recent releases pair correctness work on the reload path with integrations aimed at editors: compile_commands.json generation for LSP servers, and breakpoint injection in Positron.

◆ Where it's heading

Two threads run in parallel. One tightens namespace lifecycle handling — running unload hooks on reload, keeping the old namespace and DLL loaded so dangling references survive, demoting .onUnload() errors to warnings so a broken hook cannot block reloading. The other exports development metadata so external tools can reason about a package's compiled sources.

◆ Prediction

Expect deeper Positron and LSP integration, plus continued hardening of reload semantics as R restricts direct namespace manipulation further.

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.
