What is logger?

R's logging package handed to new maintainers and rebuilt from the inside out

logger structures R logging around four composable pieces — a level threshold, a formatter, a layout and an appender — a design fixed at the 2018 CRAN release and unchanged since. The recent work is all underneath it. 0.4.0 made metadata computation lazy so expensive fields cost nothing unless a layout uses them, swapped the custom background-process appender for mirai, and added native GitHub Actions output. 0.4.1 followed with elapsed-time logging, call site location exposed to layouts, a cli-based formatter, and knitr chunk timing. 0.4.2 is a small maintenance release adding an ntfy appender.

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.

R's logging package handed to new maintainers and rebuilt from the inside out

◆ Current state

logger structures R logging around four composable pieces — a level threshold, a formatter, a layout and an appender — a design fixed at the 2018 CRAN release and unchanged since. The recent work is all underneath it. 0.4.0 made metadata computation lazy so expensive fields cost nothing unless a layout uses them, swapped the custom background-process appender for mirai, and added native GitHub Actions output. 0.4.1 followed with elapsed-time logging, call site location exposed to layouts, a cli-based formatter, and knitr chunk timing. 0.4.2 is a small maintenance release adding an ntfy appender.

◆ Where it's heading

Two things stand out. The original four-part architecture has absorbed six years of additions without being renegotiated — every new capability arrives as another formatter, layout or appender rather than a change to the contract. And the contributor pattern has shifted: 0.3.0 collected two years of scattered community patches, while 0.4.0 and 0.4.1 are concentrated work from a small number of prolific R-infrastructure maintainers, which reads as a handover of stewardship rather than a maintenance lull ending.

◆ Prediction

The pluggable design means new destinations and formatters are the path of least resistance, so expect further appenders in the mold of ntfy and Slack rather than changes to the core logging contract.

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.
