  Changes between 1.1.1 and 3.0.0 [xx XXX xxxx]
 
+  *) Correct the extended master secret constant on EBCDIC systems. Without this
+     fix TLS connections between an EBCDIC system and a non-EBCDIC system that
+     negotiate EMS will fail. Unfortunately this also means that TLS connections
+     between EBCDIC systems with this fix, and EBCDIC systems without this
+     fix will fail if they negotiate EMS.
+     [Matt Caswell]
+
+  *) Changed the library initialisation so that the config file is now loaded
+     by default. This was already the case for libssl. It now occurs for both
+     libcrypto and libssl. Use the OPENSSL_INIT_NO_LOAD_CONFIG option to
+     OPENSSL_init_crypto() to suppress automatic loading of a config file.
+     [Matt Caswell]
+
+  *) Introduced new error raising macros, ERR_raise() and ERR_raise_data(),
+     where the former acts as a replacement for ERR_put_error(), and the
+     latter replaces the combination ERR_put_error()+ERR_add_error_data().
+     ERR_raise_data() adds more flexibility by taking a format string and
+     an arbitrary number of arguments following it, to be processed with
+     BIO_snprintf().
+     [Richard Levitte]
+
+  *) Introduced a new function, OSSL_PROVIDER_available(), which can be used
+     to check if a named provider is loaded and available.  When called, it
+     will also activate all fallback providers if such are still present.
+     [Richard Levitte]
+
+  *) Enforce a minimum DH modulus size of 512 bits.
+     [Bernd Edlinger]
+
+  *) Changed DH parameters to generate the order q subgroup instead of 2q.
+     Previously generated DH parameters are still accepted by DH_check
+     but DH_generate_key works around that by clearing bit 0 of the
+     private key for those. This avoids leaking bit 0 of the private key.
+     [Bernd Edlinger]
+
+  *) Significantly reduce secure memory usage by the randomness pools.
+     [Paul Dale]
+
   *) {CRYPTO,OPENSSL}_mem_debug_{push,pop} are now no-ops and have been
      deprecated.

   *) Support SM2 signing and verification schemes with X509 certificate.

-  *) The macro SYSerr() was changed to take a function name, not
-     a numeric value; the SYS_F_xxx defines were removed.

   *) Use SHA256 as the default digest for TS query in the ts app.
