 ## [Unreleased]
+### Added
+- Added automatic configuration of Linked RAs.
+- Send provisioner configuration on Linked RAs.
 ### Changed
-- Certificates signed by an issuer using an RSA key will be signed using the same algorithm as the issuer certificate was signed with. The signature will no longer default to PKCS #1. For example, if the issuer certificate was signed using RSA-PSS with SHA-256, a new certificate will also be signed using RSA-PSS with SHA-256.
-- Support two latest versions of Go (1.18, 1.19)
-- Vadlidate revocation serial number (either base 10 or prefixed with an appropriate base)

+- Sanitize TLS options.
+- Allow different representations of the serial number on X509 revocation.
