  OpenSSL CHANGES
  _______________
 
- Changes between 0.9.7e and 0.9.8  [xx XXX xxxx]
+ Changes between 0.9.7h and 0.9.8  [xx XXX xxxx]
+
+  *) Add attribute functions to EVP_PKEY structure. Modify
+     PKCS12_create() to recognize a CSP name attribute and
+     use it. Make -CSP option work again in pkcs12 utility.
+     [Steve Henson]
+
+  *) Add new functionality to the bn blinding code:
+     - automatic re-creation of the BN_BLINDING parameters after
+       a fixed number of uses (currently 32)
+     - add new function for parameter creation
+     - introduce flags to control the update behaviour of the
+       BN_BLINDING parameters
+     - hide BN_BLINDING structure
+     Add a second BN_BLINDING slot to the RSA structure to improve
+     performance when a single RSA object is shared among several
+     threads.
+     [Nils Larsch]
+
+  *) Add support for DTLS.
+     [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie]
+
+  *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1)
+     to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file()
+     [Walter Goulet]
+
+  *) Remove buggy and incompletet DH cert support from
+     ssl/ssl_rsa.c and ssl/s3_both.c
+     [Nils Larsch]
+
+  *) Use SHA-1 instead of MD5 as the default digest algorithm for
+     the apps/openssl applications.
+     [Nils Larsch]
+
+  *) Compile clean with "-Wall -Wmissing-prototypes
+     -Wstrict-prototypes -Wmissing-declarations -Werror". Currently
+     DEBUG_SAFESTACK must also be set.
+     [Ben Laurie]
 
   *) Change ./Configure so that certain algorithms can be disabled by default.
      The new counterpiece to "no-xxx" is "enable-xxx".

- Changes between 0.9.7e and 0.9.7f  [XX xxx XXXX]
+ Changes between 0.9.7g and 0.9.7h  [XX xxx XXXX]
+
+  *) Make a new fixed-window mod_exp implementation the default for
+     RSA, DSA, and DH private-key operations so that the sequence of
+     squares and multiplies and the memory access pattern are
+     independent of the particular secret key.  This will mitigate
+     cache-timing and potential related attacks.
+
+     BN_mod_exp_mont_consttime() is the new exponentiation implementation,
+     and this is automatically used by BN_mod_exp_mont() if the new flag
+     BN_FLG_EXP_CONSTTIME is set for the exponent.  RSA, DSA, and DH
+     will use this BN flag for private exponents unless the flag
+     RSA_FLAG_NO_EXP_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME, or
+     DH_FLAG_NO_EXP_CONSTTIME, respectively, is set.
+
+     [Matthew D Wood (Intel Corp), with some changes by Bodo Moeller]
+
+  *) Change the client implementation for SSLv23_method() and
+     SSLv23_client_method() so that is uses the SSL 3.0/TLS 1.0
+     Client Hello message format if the SSL_OP_NO_SSLv2 option is set.
+     (Previously, the SSL 2.0 backwards compatible Client Hello
+     message format would be used even with SSL_OP_NO_SSLv2.)
+     [Bodo Moeller]
+
+  *) Add support for smime-type MIME parameter in S/MIME messages which some
+     clients need.
+     [Steve Henson]
+
+  *) New function BN_MONT_CTX_set_locked() to set montgomery parameters in
+     a threadsafe manner. Modify rsa code to use new function and add calls
+     to dsa and dh code (which had race conditions before).
+     [Steve Henson]
+
+  *) Include the fixed error library code in the C error file definitions
+     instead of fixing them up at runtime. This keeps the error code
+     structures constant.
+     [Steve Henson]
+
+ Changes between 0.9.7f and 0.9.7g  [11 Apr 2005]
+
+  *) Fixes for newer kerberos headers. NB: the casts are needed because
+     the 'length' field is signed on one version and unsigned on another
+     with no (?) obvious way to tell the difference, without these VC++
+     complains. Also the "definition" of FAR (blank) is no longer included
+     nor is the error ENOMEM. KRB5_PRIVATE has to be set to 1 to pick up
+     some needed definitions.
+     [Steve Henson]
+
+  *) Undo Cygwin change.
+     [Ulf Möller]
+
+  *) Added support for proxy certificates according to RFC 3820.
+     Because they may be a security thread to unaware applications,
+     they must be explicitely allowed in run-time.  See
+     docs/HOWTO/proxy_certificates.txt for further information.

+
+ Changes between 0.9.7e and 0.9.7f  [22 Mar 2005]
+
+  *) Use (SSL_RANDOM_VALUE - 4) bytes of pseudo random data when generating
+     server and client random values. Previously
+     (SSL_RANDOM_VALUE - sizeof(time_t)) would be used which would result in
+     less random data when sizeof(time_t) > 4 (some 64 bit platforms).
+
+     This change has negligible security impact because:
+
+     1. Server and client random values still have 24 bytes of pseudo random
+        data.
+
+     2. Server and client random values are sent in the clear in the initial
+        handshake.
+
+     3. The master secret is derived using the premaster secret (48 bytes in
+        size for static RSA ciphersuites) as well as client server and random
+        values.
+
+     The OpenSSL team would like to thank the UK NISCC for bringing this issue
+     to our attention.
