### 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.
+
+ *David von Oheimb*
+
* Windows thread synchronization uses read/write primitives (SRWLock) when
supported by the OS, otherwise CriticalSection continues to be used.
*Richard Levitte*
+ * Improved adherence to Enhanced Security Services (ESS, RFC 2634 and RFC 5035)
+ for the TSP and CMS Advanced Electronic Signatures (CAdES) implementations.
+ As required by RFC 5035 check both ESSCertID and ESSCertIDv2 if both present.
+ Correct the semantics of checking the validation chain in case ESSCertID{,v2}
+ contains more than one certificate identifier: This means that all
+ certificates referenced there MUST be part of the validation chain.
+
+ *David von Oheimb*
+
* The implementation of the EVP ciphers CAST5-ECB, CAST5-CBC, CAST5-OFB,
CAST5-CFB, BF-ECB, BF-CBC, BF-OFB, BF-CFB, IDEA-ECB, IDEC-CBC, IDEA-OFB,
IDEA-CFB, SEED-ECB, SEED-CBC, SEED-OFB, SEED-CFB, RC2-ECB, RC2-CBC,
*Antonio Iacono*
+ * Added the AuthEnvelopedData content type structure (RFC 5083) with AES-GCM
+ parameter (RFC 5084) for the Cryptographic Message Syntax (CMS). Its purpose
+ is to support encryption and decryption of a digital envelope that is both
+ authenticated and encrypted using AES GCM mode.
+
+ *Jakub Zelenka*
+
* Deprecated EC_POINT_make_affine() and EC_POINTs_make_affine(). These
functions are not widely used and now OpenSSL automatically perform this
conversion when needed.
