### Changes between 1.1.1 and 3.0 [xx XXX xxxx]
+ * The EVP_PKEY_public_check() and EVP_PKEY_param_check() functions now work for
+ more key types including RSA, DSA, ED25519, X25519, ED448 and X448.
+ Previously (in 1.1.1) they would return -2. For key types that do not have
+ parameters then EVP_PKEY_param_check() will always return 1.
+
+ * The output from numerous "printing" functions such as X509_signature_print(),
+ X509_print_ex(), X509_CRL_print_ex(), and other similar functions has been
+ amended such that there may be cosmetic differences between the output
+ observed in 1.1.1 and 3.0. This also applies to the "-text" output from the
+ x509 and crl applications.

* Windows thread synchronization uses read/write primitives (SRWLock) when
supported by the OS, otherwise CriticalSection continues to be used.
