   Major changes between OpenSSL 1.1.1 and OpenSSL 3.0.0 [under development]
 
+      o X509 certificates signed using SHA1 are no longer allowed at security
+        level 1 or higher. The default security level for TLS is 1, so
+        certificates signed using SHA1 are by default no longer trusted to
+        authenticate servers or clients.
+      o enable-crypto-mdebug and enable-crypto-mdebug-backtrace were mostly
+        disabled; the project uses address sanitize/leak-detect instead.
+      o Added OSSL_SERIALIZER, a generic serializer API.
+      o Added error raising macros, ERR_raise() and ERR_raise_data().
+      o Deprecated ERR_put_error().
+      o Added OSSL_PROVIDER_available(), to check provider availibility.
+      o Added 'openssl mac' that uses the EVP_MAC API.
+      o Added 'openssl kdf' that uses the EVP_KDF API.
+      o Add OPENSSL_info() and 'openssl info' to get built-in data.
+      o Add support for enabling instrumentation through trace and debug
+        output.
       o Changed our version number scheme and set the next major release to
         3.0.0
       o Added EVP_MAC, an EVP layer MAC API, and a generic EVP_PKEY to EVP_MAC
         bridge.
+      o Removed the heartbeat message in DTLS feature.
+      o Added EVP_KDF, an EVP layer KDF API, and a generic EVP_PKEY to EVP_KDF
+        bridge.
+      o All of the low level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
+        SHA256, SHA384, SHA512 and Whirlpool digest functions have been
+        deprecated.
+      o All of the low level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
+        RC4, RC5 and SEED cipher functions have been deprecated.
