  Changes between 1.1.1 and 3.0.0 [xx XXX xxxx]
 
+  *) Early start up entropy quality from the DEVRANDOM seed source has been
+     improved for older Linux systems.  The RAND subsystem will wait for
+     /dev/random to be producing output before seeding from /dev/urandom.
+     The seeded state is stored for future library initialisations using
+     a system global shared memory segment.  The shared memory identifier
+     can be configured by defining OPENSSL_RAND_SEED_DEVRANDOM_SHM_ID to
+     the desired value.  The default identifier is 114.
+     [Paul Dale]
+
+  *) Revised BN_generate_prime_ex to not avoid factors 2..17863 in p-1
+     when primes for RSA keys are computed.
+     Since we previously always generated primes == 2 (mod 3) for RSA keys,
+     the 2-prime and 3-prime RSA modules were easy to distinguish, since
+     N = p*q = 1 (mod 3), but N = p*q*r = 2 (mod 3). Therefore fingerprinting
+     2-prime vs. 3-prime RSA keys was possible by computing N mod 3.
+     This avoids possible fingerprinting of newly generated RSA modules.
+     [Bernd Edlinger]
+
+  *) 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]
 
-  *) Added a new FUNCerr() macro that takes a function name.
-     The macro SYSerr() is deprecated.
-     [Rich Salz]
-
   *) Significantly reduce secure memory usage by the randomness pools.
