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 b3doc — 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.
A small B-Cubed utility for turning R Markdown into publishable docs
b3doc converts R Markdown to Markdown and rewrites front matter for documentation published by the B-Cubed project, which is its entire remit. Three releases exist: the initial pair of functions, a generalisation of the front-matter replacement, and a hardening pass that removed regex from the replace argument and standardised figures at 300 DPI. It sits in the b-cubed-eu family alongside impIndicator and shares contributors with the wider Belgian biodiversity tooling group.

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.

The direction is toward predictability over flexibility. The replace argument arrived in 0.2.0 generalising the earlier logo-specific behaviour, then 0.3.0 pulled regex support back out of it because escape characters and over-broad matches caused unintended edits. That is a maintainer choosing a narrower tool that fails obviously over a general one that fails quietly — a reasonable trade for a package that rewrites files in place.
Expect continued small releases driven by the documentation pipeline's needs, with output-quality defaults and front-matter handling the likely subjects rather than new functions.
