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 authentik and Casdoor — release velocity, themes, recent moves, and the top alternatives to consider.
Seven release candidates in eight days, and rc7 quietly carries the endpoint agent.
authentik is deep in the 2026.8.0 release-candidate train — seven RCs, six of them fired on a single day in early August and rc7 a week later. Most of the train is CI plumbing, docs, and cherry-picked fixes, but rc7 is an order of magnitude larger and lands substantive work: an Actors primitive in core, an enterprise Agent that requires a domain join and its own API scope, OAuth2 token exchange delegation, and a CAS source integration.
Casdoor is spending its release cadence moving auth checks from the client to the server
Casdoor is in a tight patch cadence: six tagged releases inside a week, most carrying a single commit. The substance is concentrated in identity enforcement rather than features - password rotation and MFA setup are now enforced server-side, admin updates to a user respect the column whitelist, sessions and tokens are revoked when a user is forbidden, and phone numbers are normalised before they are stored. The remainder is release plumbing and a PostgreSQL query fix.

Two threads run through the branch. The identity surface keeps broadening at the protocol edge — CAS sources, WS-Fed, token exchange delegation, GitGuardian — while the enterprise tier grows an endpoint story with Agents and Actors, pushing authentik past browser-mediated SSO toward machine and device identity. The heavy CI investment across the RCs (test job split into ten, attestation and metadata fixes, release-branch validation) reads as release engineering being hardened ahead of a major.
2026.8.0 GA is the next step, and it is where the Agents and Actors work becomes a real story rather than a cherry-pick line. Expect the RC train to close out with fix-only candidates.

Read together, these commits describe one job: closing the gap between what the console enforces and what the backend enforces. Several of them move a check that previously lived in the UI into the server, which is the work of a project being deployed into environments that audit it. New authentication providers and integrations have thinned relative to this hardening pass.
The next releases most likely continue the same sweep - remaining endpoints where an admin or user request is trusted more than the server verifies - rather than adding a new identity provider.
