 - 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
+  same algorithm used to sign the issuer certificate. 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).
 - Validate 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.
