Argo CD 3.5 RC adds UI ApplicationSet previews and beta impersonation
The release candidate drops a new ApplicationSet UI that shows deployment diffs before sync, letting teams catch mistakes early. It also promotes impersonation and source hydrator to beta, adds Helm 4 support, repo-server mTLS, and source integrity checks, tightening multi-tenant security. Test it now to shape the final 3.5 release.
