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 fish shell — 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.
Four minor versions in five months, and the shell's remaining work is almost all interaction detail.
fish is deep into the 4.x Rust-era grind: 4.4.0 through 4.8.1 land in roughly five months, each carrying 60-234 commits from a steadily widening contributor base with new committers in every release. The changes are overwhelmingly interactive — keybindings, completion pager behavior, prompt handling, color variables. Each minor release is followed within days or weeks by a patch cleaning up its own regressions.

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 underneath the interaction polish. One is shedding legacy C-era dependencies: terminfo and ncurses are gone for good, and 4.8.0 moves Rust-side translation off GNU gettext onto Fluent with purpose-built tooling. The other is fitting into a modern terminal environment rather than working around old ones — OSC 133 prompt marking, systemd run0's prompt variables, emoji width defaulting to 2. The project is trading compatibility with terminals nobody runs for fidelity in the ones people actually use.
Expect the gettext-to-Fluent migration to extend from Rust source into fish script messages, since 4.8.0 flags script translations as the remaining holdout, and expect the release-then-patch rhythm to continue given every minor in this window needed one.
