+## [0.31.0] - 2026-09-25
+
+### Added
+
+- Add support for ML-DSA keys (ML-DSA-44, ML-DSA-65, and ML-DSA-87) in the
+  `step ca`, `step certificate`, and `step crypto key` commands, including
+  X.509 certificate and CRL signing, and ACME `device-attest-01` challenges.
+  SSH and JOSE commands do not support ML-DSA keys yet (smallstep/cli#1698,
+  smallstep/crypto#1098, smallstep/crypto#1123).
+- Show the full ML-DSA parameter set in the public key algorithm section when
+  inspecting certificates and certificate requests (smallstep/certinfo#94).
+- Allow subject DN components in MacKMS certificate URIs, and create MacKMS
+  signers without a label (smallstep/crypto#1073, smallstep/crypto#1134).
