  Changes between 0.9.6 and 0.9.7  [xx XXX 2000]
 
-  *) Add another call level for memory allocation routines, thereby
-     allowing memory allocation callbacks that can be given file
-     name and line number information.  The basic functionality
-     remains, as well as the original possibility to just replace
-     malloc(), realloc() and free().  The new functions that can be
-     registered help users provide variants of malloc(), realloc()
-     and free() that take two extra arguments, a const char* and an
-     int.  To register and find out the current settings for those
-     hooks, the following functions are provided:
+  *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
+     skipped when using openssl x509 multiple times on a single input file,
+     e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
+     [Bodo Moeller]
+
+  *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
+     set string type: to handle setting ASN1_TIME structures. Fix ca
+     utility to correctly initialize revocation date of CRLs.
+     [Steve Henson]
+
+  *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
+     the clients preferred ciphersuites and rather use its own preferences.
+     Should help to work around M$ SGC (Server Gated Cryptography) bug in
+     Internet Explorer by ensuring unchanged hash method during stepup.
+     [Lutz Jaenicke]
+
+  *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
+     to aes and add a new 'exist' option to print out symbols that don't
+     appear to exist.
+     [Steve Henson]
+
+  *) Additional options to ocsp utility to allow flags to be set and
+     additional certificates supplied.
+     [Steve Henson]
+
+  *) Add the option -VAfile to 'openssl ocsp', so the user can give the
+     OCSP client a number of certificate to only verify the response
+     signature against.
+     [Richard Levitte]
+
+  *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
+     Bleichenbacher's DSA attack.
+     [Ulf Moeller, Bodo Moeller]
+
+  *) Update Rijndael code to version 3.0 and change EVP AES ciphers to
+     handle the new API. Currently only ECB, CBC modes supported. Add new
+     AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
+     for TLS" draft-ietf-tls-ciphersuite-03.txt.
+     [Ben Laurie, Steve Henson]
+
+  *) In the NCONF_...-based implementations for CONF_... queries
+     (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
+     a temporary CONF structure with the data component set to NULL
+     (which gives segmentation faults in lh_retrieve).
+     Instead, use NULL for the CONF pointer in CONF_get_string and
+     CONF_get_number (which may use environment variables) and directly
+     return NULL from CONF_get_section.
+     [Bodo Moeller]
+
+  *) Fix potential buffer overrun for EBCDIC.
+     [Ulf Moeller]
+
+  *) New function OCSP_copy_nonce() to copy nonce value (if present) from
+     request to response.
+     [Steve Henson]
+
+  *) Functions for OCSP responders. OCSP_request_onereq_count(),
+     OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
+     extract information from a certificate request. OCSP_response_create()
+     creates a response and optionally adds a basic response structure.
+     OCSP_basic_add1_status() adds a complete single response to a basic
+     reponse and returns the OCSP_SINGLERESP structure just added (to allow
+     extensions to be included for example). OCSP_basic_add1_cert() adds a
+     certificate to a basic response and OCSP_basic_sign() signs a basic
+     response with various flags. New helper functions ASN1_TIME_check()
+     (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
+     (converts ASN1_TIME to GeneralizedTime).
+     [Steve Henson]
+
+  *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
+     in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
+     structure from a certificate. X509_pubkey_digest() digests tha public_key
+     contents: this is used in various key identifiers. 
+     [Steve Henson]
+
+  *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
+     keyUsage if basicConstraints absent for a CA.
+     [Steve Henson]
+
+  *) Make SMIME_write_PKCS7() write mail header values with a format that
+     is more generally accepted (no spaces before the semicolon), since
+     some programs can't parse those values properly otherwise.  Also make
+     sure BIO's that break lines after each write do not create invalid
+     headers.
+     [Richard Levitte]
+
+  *) Make sk_sort() tolerate a NULL argument.
+     [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
+
+  *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
+     passed by the function are trusted implicitly. If any of them signed the
+     reponse then it is assumed to be valid and is not verified.
+     [Steve Henson]
+
+  *) Zero the premaster secret after deriving the master secret in
+     DH ciphersuites.
+     [Steve Henson]
+
+  *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
+     to data. This was previously part of the PKCS7 ASN1 code. This
+     was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
+     [Steve Henson, reported by Kenneth R. Robinette
+				<support@securenetterm.com>]
+
+  *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
+     routines: without these tracing memory leaks is very painful.
+     Fix leaks in PKCS12 and PKCS7 routines.
+     [Steve Henson]
+
+  *) Fix for Irix with NO_ASM.
+     ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
+
+  *) Add some EVP_add_digest_alias registrations (as found in
+     OpenSSL_add_all_digests()), to SSL_library_init()
+     aka OpenSSL_add_ssl_algorithms().  This provides improved
+     compatibility with peers using X.509 certificates
+     with unconventional AlgorithmIdentifier OIDs.
+     [Bodo Moeller]
+
+  *) ./config script fixes.
+     [Ulf Moeller, Richard Levitte]
+
+  *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
+     Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
+     effectively meant GeneralizedTime would never be used. Now it
+     is initialised to -1 but X509_time_adj() now has to check the value
+     and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
+     V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
+     [Steve Henson, reported by Kenneth R. Robinette
+				<support@securenetterm.com>]
+
+  *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
+     result in a zero length in the ASN1_INTEGER structure which was
+     not consistent with the structure when d2i_ASN1_INTEGER() was used
+     and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
+     to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
+     where it did not print out a minus for negative ASN1_INTEGER.
+     [Steve Henson]
+
+  *) Fix 'openssl passwd -1'.
+     [Bodo Moeller]
+
+  *) Add summary printout to ocsp utility. The various functions which
+     convert status values to strings have been renamed to:
+     OCSP_response_status_str(), OCSP_cert_status_str() and
+     OCSP_crl_reason_str() and are no longer static. New options
+     to verify nonce values and to disable verification. OCSP response
+     printout format cleaned up.
+     [Steve Henson]
+
+  *) Add additional OCSP certificate checks. These are those specified
+     in RFC2560. This consists of two separate checks: the CA of the
+     certificate being checked must either be the OCSP signer certificate
+     or the issuer of the OCSP signer certificate. In the latter case the
+     OCSP signer certificate must contain the OCSP signing extended key
+     usage. This check is performed by attempting to match the OCSP
+     signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
+     in the OCSP_CERTID structures of the response.
+     [Steve Henson]
+
+  *) Initial OCSP certificate verification added to OCSP_basic_verify()
+     and related routines. This uses the standard OpenSSL certificate
+     verify routines to perform initial checks (just CA validity) and
+     to obtain the certificate chain. Then additional checks will be
+     performed on the chain. Currently the root CA is checked to see
+     if it is explicitly trusted for OCSP signing. This is used to set
+     a root CA as a global signing root: that is any certificate that
+     chains to that CA is an acceptable OCSP signing certificate.
+     [Steve Henson]
+
+  *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
+     extensions from a separate configuration file.
+     As when reading extensions from the main configuration file,
+     the '-extensions ...' option may be used for specifying the
+     section to use.
+     [Massimiliano Pala <madwolf@comune.modena.it>]
+
+  *) Change PKCS12_key_gen_asc() so it can cope with non null
+     terminated strings whose length is passed in the passlen
+     parameter, for example from PEM callbacks. This was done
+     by adding an extra length parameter to asc2uni().
+     [Steve Henson, reported by <oddissey@samsung.co.kr>]
+
+  *) New OCSP utility. Allows OCSP requests to be generated or
+     read. The request can be sent to a responder and the output
+     parsed, outputed or printed in text form. Not complete yet:
+     still needs to check the OCSP response validity.
+     [Steve Henson]
+
+  *) New subcommands for 'openssl ca':
+     'openssl ca -status <serial>' prints the status of the cert with
+     the given serial number (according to the index file).
+     'openssl ca -updatedb' updates the expiry status of certificates
+     in the index file.
+     [Massimiliano Pala <madwolf@comune.modena.it>]
+
+  *) New '-newreq-nodes' command option to CA.pl.  This is like
+     '-newreq', but calls 'openssl req' with the '-nodes' option
+     so that the resulting key is not encrypted.
+     [Damien Miller <djm@mindrot.org>]
+
+  *) New configuration for the GNU Hurd.
+     [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
+
+  *) Initial code to implement OCSP basic response verify. This
+     is currently incomplete. Currently just finds the signer's
+     certificate and verifies the signature on the response.
+     [Steve Henson]
+
+  *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
+     value of OPENSSLDIR.  This is available via the new '-d' option
+     to 'openssl version', and is also included in 'openssl version -a'.
+     [Bodo Moeller]
+
+  *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
+     call failed, free the DSA structure.
+     [Bodo Moeller]
+
+  *) Allowing defining memory allocation callbacks that will be given
+     file name and line number information in additional arguments
+     (a const char* and an int).  The basic functionality remains, as
+     well as the original possibility to just replace malloc(),
+     realloc() and free() by functions that do not know about these
+     additional arguments.  To register and find out the current
+     settings for extended allocation functions, the following
+     functions are provided:
 
 	CRYPTO_set_mem_ex_functions
 	CRYPTO_set_locked_mem_ex_functions
 	CRYPTO_get_mem_ex_functions
 	CRYPTO_get_locked_mem_ex_functions
 
-     They work the same way as the corresponding CRYPTO_set_mem_functions
-     and friends with one exception: giving NULL as arguments will restore
-     the internal hooks to internal routines and will still make the above
-     functions return 1 and not 0.
-
-     This functionality was created as a direct request to add the
-     possibility to interface with the Windows debugging routines
-     _malloc_dbg, _realloc_dbg and _free_dbg.
-     [Richard Levitte]
+     These work the same way as CRYPTO_set_mem_functions and friends.
+     CRYPTO_get_[locked_]mem_functions now writes 0 where such an
+     extended allocation function is enabled.
+     Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
+     a conventional allocation function is enabled.
+     [Richard Levitte, Bodo Moeller]
 
   *) Fix to uni2asc() to cope with zero length Unicode strings.
      These are present in some PKCS#12 files.

   *) Change the Unix RAND_poll() variant to be able to poll several
-     random devices and only read data for a small fragment of time
-     to avoid hangs.  Also separate out the Unix variant to it's own
-     file, rand_unix.c.  For VMS, there's a currently-empty rand_vms.c.

+     defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
