### Changes between 1.1.1 and 3.0 [xx XXX xxxx] ###
+ * Added OSSL_PARAM_BLD to the public interface. This allows OSSL_PARAM
+ arrays to be more easily constructed via a series of utility functions.
+ Create a parameter builder using OSSL_PARAM_BLD_new(), add parameters using
+ the various push functions and finally convert to a passable OSSL_PARAM
+ array using OSSL_PARAM_BLD_to_param().
+
+ * Paul Dale *
+
+ * EVP_PKEY_get0_RSA(), EVP_PKEY_get0_DSA(), EVP_PKEY_get0_DH(), and
+ EVP_PKEY_get0_EC_KEY() can now handle EVP_PKEYs with provider side
+ internal keys, if they correspond to one of those built in types.
+
+ *Richard Levitte*
+
* Added EVP_PKEY_set_type_by_keymgmt(), to initialise an EVP_PKEY to
contain a provider side internal key.
