  Changes between 0.9.6 and 0.9.7  [xx XXX 2000]
 
+  *) 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
+
+     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.
+     [Steve Henson]
+
+  *) Finish off removing the remaining LHASH function pointer casts.
+     There should no longer be any prototype-casting required when using
+     the LHASH abstraction, and any casts that remain are "bugs". See
+     the callback types and macros at the head of lhash.h for details
+     (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
+     [Geoff Thorpe]
+
+  *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
+     If an EGD or PRNGD is running and enough entropy is returned, automatic
+     seeding like with /dev/[u]random will be performed.
+     Positions tried are: /etc/entropy, /var/run/egd-pool.
+     [Lutz Jaenicke]
+
+  *) Change the Unix RAND_poll() variant to be able to poll several
+     random devices, as specified by DEVRANDOM, until a sufficient amount
+     of data has been collected.   We spend at most 10 ms on each file
+     (select timeout) and read in non-blocking mode.  DEVRANDOM now
+     defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
+     (previously it was just the string "/dev/urandom"), so on typical
+     platforms the 10 ms delay will never occur.
+     Also separate out the Unix variant to its own file, rand_unix.c.
+     For VMS, there's a currently-empty rand_vms.c.
+     [Richard Levitte]
+
+  *) Move OCSP client related routines to ocsp_cl.c. These
+     provide utility functions which an application needing
+     to issue a request to an OCSP responder and analyse the
+     response will typically need: as opposed to those which an
+     OCSP responder itself would need which will be added later.
+
+     OCSP_request_sign() signs an OCSP request with an API similar
+     to PKCS7_sign(). OCSP_response_status() returns status of OCSP
+     response. OCSP_response_get1_basic() extracts basic response
+     from response. OCSP_resp_find_status(): finds and extracts status
+     information from an OCSP_CERTID structure (which will be created
+     when the request structure is built). These are built from lower
+     level functions which work on OCSP_SINGLERESP structures but
+     wont normally be used unless the application wishes to examine
+     extensions in the OCSP response for example.
+
+     Replace nonce routines with a pair of functions.
+     OCSP_request_add1_nonce() adds a nonce value and optionally
+     generates a random value. OCSP_check_nonce() checks the
+     validity of the nonce in an OCSP response.
+     [Steve Henson]
+
+  *) Change function OCSP_request_add() to OCSP_request_add0_id().
+     This doesn't copy the supplied OCSP_CERTID and avoids the
+     need to free up the newly created id. Change return type
+     to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
+     This can then be used to add extensions to the request.
+     Deleted OCSP_request_new(), since most of its functionality
+     is now in OCSP_REQUEST_new() (and the case insensitive name
+     clash) apart from the ability to set the request name which
+     will be added elsewhere.
+     [Steve Henson]
+
+  *) Update OCSP API. Remove obsolete extensions argument from
+     various functions. Extensions are now handled using the new
+     OCSP extension code. New simple OCSP HTTP function which 
+     can be used to send requests and parse the response.
+     [Steve Henson]
+
+  *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
+     ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
+     uses the special reorder version of SET OF to sort the attributes
+     and reorder them to match the encoded order. This resolves a long
+     standing problem: a verify on a PKCS7 structure just after signing
+     it used to fail because the attribute order did not match the
+     encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
+     it uses the received order. This is necessary to tolerate some broken
+     software that does not order SET OF. This is handled by encoding
+     as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
+     to produce the required SET OF.
+     [Steve Henson]
+
+  *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
+     OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
+     files to get correct declarations of the ASN.1 item variables.
+     [Richard Levitte]
+
+  *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
+     PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
+     asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
+     NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
+     New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
+     ASN1_ITEM and no wrapper functions.
+     [Steve Henson]
+
+  *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
+     replace the old function pointer based I/O routines. Change most of
+     the *_d2i_bio() and *_d2i_fp() functions to use these.
+     [Steve Henson]
+
+  *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
+     lines, recognice more "algorithms" that can be deselected, and make
+     it complain about algorithm deselection that isn't recognised.
+     [Richard Levitte]
+
+  *) New ASN1 functions to handle dup, sign, verify, digest, pack and
+     unpack operations in terms of ASN1_ITEM. Modify existing wrappers
+     to use new functions. Add NO_ASN1_OLD which can be set to remove
+     some old style ASN1 functions: this can be used to determine if old
+     code will still work when these eventually go away.
+     [Steve Henson]
+
+  *) New extension functions for OCSP structures, these follow the
+     same conventions as certificates and CRLs.
+     [Steve Henson]
+
   *) New function X509V3_add1_i2d(). This automatically encodes and
      adds an extension. Its behaviour can be customised with various
      flags to append, replace or delete. Various wrappers added for

      512 bits], about 30% for larger ones [1024 or 2048 bits].)
      [Bodo Moeller]
 
-  *) Disable ssl2_peek and ssl3_peek (i.e., both implementations
-     of SSL_peek) because they both are completely broken.
-     For fixing this, the internal read functions now have an additional
-     'peek' parameter, but the actual peek functionality has not
-     yet been implemented.
+  *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
+     SSL3_RT_APPLICATION_DATA, return 0.
+     Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
+     [Bodo Moeller]
+
+  *) Fix SSL_peek:
+     Both ssl2_peek and ssl3_peek, which were totally broken in earlier
+     releases, have been re-implemented by renaming the previous
+     implementations of ssl2_read and ssl3_read to ssl2_read_internal
+     and ssl3_read_internal, respectively, and adding 'peek' parameters
+     to them.  The new ssl[23]_{read,peek} functions are calls to
+     ssl[23]_read_internal with the 'peek' flag set appropriately.
+     A 'peek' parameter has also been added to ssl3_read_bytes, which
+     does the actual work for ssl3_read_internal.
      [Bodo Moeller]
 
   *) New function BN_kronecker.
