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 connectapi — 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.
connectapi is becoming the scripted administration surface for Posit Connect.
connectapi is the R client for the Posit Connect server API, covering content deployment, scheduling, usage data and permissions. Recent releases concentrate on OAuth integrations, which went from unmanaged to full CRUD in 0.9.0 and reached Connect Cloud in 0.12.0. Interleaved with that is steady removal of functions deprecated several versions back.

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 directions run in parallel. The package is widening from a deployment client into an administration surface, through integrations, content search and content locking, which lets Connect configuration live in code rather than in the admin UI. At the same time it prunes aggressively: image helpers deprecated since 0.3.1 and job functions deprecated since 0.6.0 were both removed in this window, with set_schedule_*()'s activate argument on the same path. The result is a smaller but more capable API.
The deprecation cycle is announced in advance, so the activate argument is the next likely removal. On the feature side, Connect Cloud support has so far landed only for OAuth and looks unfinished.
