+ * Added an implementation of CMP and CRMF (RFC 4210, RFC 4211 RFC 6712).
+   This adds crypto/cmp/, crpyto/crmf/, and test/cmp_*.
+   See L<OSSL_CMP_exec_IR_ses(3)> as starting point.

+   *David von Oheimb*
+
+ * Generalized the HTTP client code from crypto/ocsp/ into crpyto/http/.
+   The legacy OCSP-focused and only partly documented API is retained.

   * enable-crypto-mdebug and enable-crypto-mdebug-backtrace were mostly
     disabled; the project uses address sanitize/leak-detect instead.
+  * Added a Certificate Management Protocol (CMP, RFC 4210) implementation
+    also covering CRMF (RFC 4211) and HTTP transfer (RFC 6712).
+    It is part of the crypto lib, while a 'cmp' app using it is in preparation.
+    All widely used CMP features are supported for both clients and servers.
+  * Added a proper HTTP(S) client to libcrypto supporting GET and POST,
+    redirection, plain and ASN.1-encoded contents, proxies, and timeouts.
   * Added OSSL_SERIALIZER, a generic serializer API.
   * Added OSSL_PARAM_BLD, an easier to use API to OSSL_PARAM.
   * Added error raising macros, ERR_raise() and ERR_raise_data().
