About cert-manager
cert-manager's 1.21 line is about failure handling: backoff caps, renewal policies and clearer auth errors
cert-manager is running the 1.21 pre-release train through alpha.0, alpha.1 and now beta.0. The changes cluster around what happens when certificate issuance goes wrong: a configurable cap on CertificateRequest retry backoff, a new AuthFailed issuer condition that separates bad Venafi credentials from transient infrastructure failures, and certificate renewal policies.
