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 osrm.backend — 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.
osrm.backend stopped trusting upstream binaries and started shipping its own
osrm.backend installs and manages OSRM routing servers from R. Through 0.3.x it fetched official upstream binaries and patched around their runtime dependencies. 0.4.0 in July 2026 changed the supply chain: the package now ships self-built, immutable OSRM binaries for macOS (Intel and Apple Silicon), Linux (x86_64 and arm64) and Windows, built by the maintainer and bundled with runtime libraries like Intel TBB.

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 package is moving from wrapper toward distribution channel. The maintainer-built binaries are the default provider, with the official ones retained behind osrm_binaries_provider = 'official'. Integrity verification switched to GitHub release asset digests with checksums.txt as fallback, so new binary builds no longer require a package update to be trusted. Earlier releases show the same instinct — 0.3.0 added an osrm_gui() Shiny explorer and a server registry rather than leaving those to users.
With the build matrix and verification path in place, the next work is likely validating newer upstream OSRM versions against the existing binary pipeline rather than changing the installation model. Whether the maintainer can sustain a five-platform build matrix is the open question the entries do not answer.
