What is g6R?

An R binding whose releases are mostly the upstream JS graph engine arriving, plus port ergonomics.

g6R wraps AntV's G6 graph engine as an htmlwidget, with Shiny proxy functions for data updates, layout control and mouse position read-back. The current release bundles G6 5.1.1 and ships the widget as a single self-contained bundle, having removed the split chunk. Recent work has concentrated on ports, the connection points nodes expose, with a new label-bottom placement, a larger default radius and a quieter hover state.

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.

2.5

An R binding whose releases are mostly the upstream JS graph engine arriving, plus port ergonomics.

◆ Current state

g6R wraps AntV's G6 graph engine as an htmlwidget, with Shiny proxy functions for data updates, layout control and mouse position read-back. The current release bundles G6 5.1.1 and ships the widget as a single self-contained bundle, having removed the split chunk. Recent work has concentrated on ports, the connection points nodes expose, with a new label-bottom placement, a larger default radius and a quieter hover state.

◆ Where it's heading

Two threads run through the record. One is upstream tracking: the 0.6.5 engine bump alone restored the SVG renderer, fixed a combo-related canvas crash and pulled in new node and edge query APIs, which is a lot of user-visible change that this package did not author. The other is R-side ergonomics, where ports have been reworked in three consecutive releases and 0.5.0 added data validation strict enough that the notes warn existing code may break. Layout behaviour has moved toward explicit control, with recomputation now opt-in via an option and a dedicated proxy function.

◆ Prediction

The port work looks unfinished given three releases in a row on it, so more placement and styling options are the likeliest next step, alongside another engine bump as G6 5.1.x moves. Nothing in these entries indicates a direction beyond keeping pace with upstream.

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.
