  _______________
 
- Changes between 0.9.3a and 0.9.4  [xx Jul/Aug/...? 1999]
+ Changes between 0.9.4 and 0.9.5  [xx XXX 1999]
+
+  *) Bugfix: ssl23_get_client_hello did not work properly when called in
+     state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
+     a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
+     but a retry condition occured while trying to read the rest.
+     [Bodo Moeller]
+
+  *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
+     NID_pkcs7_encrypted by default: this was wrong since this should almost
+     always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
+     the encrypted data type: this is a more sensible place to put it and it
+     allows the PKCS#12 code to be tidied up that duplicated this
+     functionality.
+     [Steve Henson]
+
+  *) Changed obj_dat.pl script so it takes its input and output files on
+     the command line. This should avoid shell escape redirection problems
+     under Win32.
+     [Steve Henson]
+
+  *) Initial support for certificate extension requests, these are included
+     in things like Xenroll certificate requests. Included functions to allow
+     extensions to be obtained and added.
+     [Steve Henson]
+
+  *) -crlf option to s_client and s_server for sending newlines as
+     CRLF (as required by many protocols).
+     [Bodo Moeller]
+
+ Changes between 0.9.3a and 0.9.4  [09 Aug 1999]
+  
+  *) Install libRSAglue.a when OpenSSL is built with RSAref.
+     [Ralf S. Engelschall]
+
+  *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
+     [Andrija Antonijevic <TheAntony2@bigfoot.com>]
+
+  *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
+     program.
+     [Steve Henson]
+
+  *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
+     DH parameters/keys (q is lost during that conversion, but the resulting
+     DH parameters contain its length).
+
+     For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
+     much faster than DH_generate_parameters (which creates parameters
+     where p = 2*q + 1), and also the smaller q makes DH computations
+     much more efficient (160-bit exponentiation instead of 1024-bit
+     exponentiation); so this provides a convenient way to support DHE
+     ciphersuites in SSL/TLS servers (see ssl/ssltest.c).  It is of
+     utter importance to use
+         SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
+     or
+         SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
+     when such DH parameters are used, because otherwise small subgroup
+     attacks may become possible!
+     [Bodo Moeller]
+
+  *) Avoid memory leak in i2d_DHparams.
+     [Bodo Moeller]
+
+  *) Allow the -k option to be used more than once in the enc program:
+     this allows the same encrypted message to be read by multiple recipients.
+     [Steve Henson]
 
   *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
      an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
