Resend
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
A side-by-side editorial comparison of Auth0 and g6R — release velocity, themes, recent moves, and the top alternatives to consider.
Auth0 hands tenants a throttle on their own noisy apps
Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.
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.

Two threads dominate. One is agent and delegation infrastructure — Agents as Principal, Token Vault Privileged Worker, Custom Token Exchange session delegation — all still in Early Access. The other is tenant self-service: rate limits, blocklists, organization search and roles, global search. Auth0 is systematically converting things that required support intervention into API-configurable policy.
The Early Access items now stacking up, particularly the agent-identity pieces, are the obvious GA candidates next, following the Flexible Password Policy path from Early Access to general availability.

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.
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.
