  Changes between 1.0.1 and 1.0.2 [xx XXX xxxx]
 
+  *) Transparently support X9.42 DH parameters when calling
+     PEM_read_bio_DHparameters. This means existing applications can handle
+     the new parameter format automatically.
+     [Steve Henson]
+
+  *) Initial experimental support for X9.42 DH parameter format: mainly
+     to support use of 'q' parameter for RFC5114 parameters.
+     [Steve Henson]
+
+  *) Add DH parameters from RFC5114 including test data to dhtest.
+     [Steve Henson]
+
   *) Support for automatic EC temporary key parameter selection. If enabled
      the most preferred EC parameters are automatically used instead of
      hardcoded fixed parameters. Now a server just has to call:

- Changes between 1.0.1 and 1.0.1a [xx XXX xxxx]
+ Changes between 1.0.1 and 1.0.1a [19 Apr 2012]
+
+  *) Check for potentially exploitable overflows in asn1_d2i_read_bio
+     BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer
+     in CRYPTO_realloc_clean.
+
+     Thanks to Tavis Ormandy, Google Security Team, for discovering this
+     issue and to Adam Langley <agl@chromium.org> for fixing it.

+
+  *) Don't allow TLS 1.2 SHA-256 ciphersuites in TLS 1.0, 1.1 connections.
+     [Adam Langley]
+
+  *) Workarounds for some broken servers that "hang" if a client hello
+     record length exceeds 255 bytes:
+ 
+     1. Do not use record version number > TLS 1.0 in initial client
+        hello: some (but not all) hanging servers will now work.
+     2. If we set OPENSSL_MAX_TLS1_2_CIPHER_LENGTH this will truncate
+        the number of ciphers sent in the client hello. This should be
+        set to an even number, such as 50, for example by passing:
+        -DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 to config or Configure.
+        Most broken servers should now work.
+     3. If all else fails setting OPENSSL_NO_TLS1_2_CLIENT will disable
+        TLS 1.2 client support entirely.
 
   *) Fix SEGV in Vector Permutation AES module observed in OpenSSH.
