6 * Version 1.7.16 (released 2007-08-07)
8 ** Fix sanity checks and return values in certificate selection.
9 In some cases, GnuTLS omitted to report suitable error codes when no
10 suitable certificate was found.
12 ** Fix gnutls-cli starttls EOF on Mac OS X.
13 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
15 ** Documentation fixes.
16 In particular, the section headings were modified for casing. By
17 Ludovic Courtes <ludovic.courtes@laas.fr>.
19 ** Update gnulib files.
21 ** API and ABI modifications:
22 No changes since last version.
24 * Version 1.7.15 (released 2007-07-02)
26 ** Fix self-tests key-id under mingw32.
28 ** Test that the Guile header files are recent enough to work.
29 Before we just tested that the command line tool 'guile' was recent
30 enough, which may not be sufficient if you still have an old
31 libguile.h header installed.
33 ** Guile bindings are now installed under $prefix by default.
34 Use --without-guile-site-dir to install it under $pkgdatadir/site/
35 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
36 Use --with-guile-site-dir=/your/own/path to specify the path manually.
37 The default, --with-guile-site-dir, will install the Guile bindings
38 under $datadir/guile/site. There is a new section 'Guile
39 Preparations' in the manual that discuss these issues.
41 ** Fix run-time library path ordering in linking the Guile bindings.
43 ** Improved manual on downloading, installing, getting help, bug reports etc.
44 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
46 ** Add Malay message translations.
47 Thanks to Sharuzzaman Ahmat Raslan <sharuzzaman@myrealbox.com>.
49 ** API and ABI modifications:
50 No changes since last version.
52 * Version 1.7.14 (released 2007-06-26)
54 ** Don't enable Guile bindings unless we have Guile 1.8 or later.
55 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
57 ** Fix memory leak during DSA signature verification.

98 new chapter 'Guile Bindings' in the manual.
100 ** Have PKCS8 parser return better error codes.
101 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
102 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
103 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
105 ** Fix mem leak for sessions with client authentication via certificates.
106 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
107 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
110 Reported by Dennis Vshivkov <walrus@amur.ru>, see
111 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333050>. Added
112 self-test tests/parse_ca.c to test regressions.

115 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
117 ** Update gnulib files.
119 ** API and ABI modifications:
120 No changes since last version.
122 * Version 1.7.11 (released 2007-05-26)
124 ** Include opencdk.h in the release.
125 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
127 ** API and ABI modifications:
128 No changes since last version.
130 * Version 1.7.10 (released 2007-05-25)
132 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
133 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
135 ** Update of gnulib files.
137 ** GnuTLS is now developed in GIT instead of CVS.
138 See <http://repo.or.cz/w/gnutls.git> for a public repository.
140 ** API and ABI modifications:
141 gnutls_x509_crt_get_raw_issuer_dn: ADD.
142 gnutls_x509_crt_get_raw_dn: ADD.
144 * Version 1.7.9 (released 2007-05-12)
146 ** X.509 certificates are preferred over OpenPGP keys.
147 This is a change in the semantics of gnutls_set_default_priority.
149 ** The included copy of OpenCDK has been updated to 0.6.1.
150 There has been some API changes in OpenCDK, and the GnuTLS layer have
151 been modified as well. Note that while there are API/ABI incompatible
152 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
153 its API/ABI have not changed. From this version on, GnuTLS requires
154 OpenCDK 0.6.0 or later.
156 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
158 ** Change certtool's default serial number from 0 to a time-based value.
160 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
161 Before, we remove the parameters field, which resulted in a slightly
162 different DER encoding which in turn caused signature verification
163 failures of GnuTLS-generated RSA certificates in some other
164 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
165 you read, this may or may not be correct, but our new behaviour appear
166 to be consistent with other widely used implementations.
168 ** Fix mem leaks in gnutls_x509_crt_print.
170 ** API and ABI modifications:
171 No changes since last version.
173 * Version 1.7.8 (released 2007-04-16)
175 ** Added examples for the authorization extension.
176 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
178 ** The examples only use gnutls_set_default_priority().
179 The exception is when DH_ANON is needed.
181 ** Improve gnutls_set_default_priority() priorities.
182 The new approach is for it to try and negotiate all secure and
183 standard mechanisms available. Currently, DH_ANON ciphersuites and
184 LZO compressions are not enabled by default, because they are,
185 respectively, insecure and non-standardized. Note that TLS 1.2 will
186 not be enabled by default in non-experimental release until it has
187 been approved by the IETF.
189 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
190 This means that to get DH_ANON and LZO compression, you'll need to
191 specify that manually using '--kx anon' or '--comp lzo'.
193 ** Minor fixes to the human display format of X.509 certificates.
195 ** New APIs to extract Distinguished Name's from X.509 certificates.
196 Based on patch from Howard Chu <hyc@symas.com>.
198 ** Improved library searching for opencdk.
199 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
200 The deprecated opencdk.m4 is no longer used.
202 ** New APIs to list supported algorithms in the library.
203 The APIs are gnutls_cipher_list, gnutls_mac_list,
204 gnutls_compression_list, gnutls_protocol_list,
205 gnutls_certificate_type_list, gnutls_kx_list, and
206 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
208 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
210 ** New configure option --disable-tls-authorization to disable tls-authz.
212 ** Fix prototype for `gnutls_psk_set_client_credentials'.
213 The last parameter was renamed from 'flags' to 'format' and the type
214 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
215 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
218 ** Fix allocation in gnutls_certificate_set_openpgp_key.
219 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
221 ** API and ABI modifications:
222 gnutls_x509_dn_t: ADD.
223 gnutls_x509_ava_st: ADD.
224 gnutls_x509_crt_get_subject,
225 gnutls_x509_crt_get_issuer: ADD.
226 gnutls_x509_dn_get_rdn_ava: ADD.
227 gnutls_cipher_list: ADD.
228 gnutls_mac_list: ADD.
229 gnutls_compression_list: ADD.
230 gnutls_protocol_list: ADD.
231 gnutls_certificate_type_list: ADD.
233 gnutls_cipher_suite_info: ADD.
235 * Version 1.7.7 (released 2007-02-22)
237 ** Support for supplemental handshake messages and authorization data.
238 Supplemental data is described in RFC 4680 and the authorization
239 extensions in draft-housley-tls-authz-extns-07.
241 ** Support for authorization data in gnutls-cli and gnutls-serv.
242 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
244 ** Fix for gnutls_x509_crt_check_hostname.
245 Before it would have reported that the certificate matched a hostname
246 when it did not have any dNSName or any CN field. Report and tiny
247 patch from "Richard W.M. Jones" <rjones@redhat.com>.
249 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
250 Tests regressions of the bug, and several other features.
252 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
253 Before there were no support for iPAddress SAN's during comparison.
255 ** New API to print information about CRL's.
256 The function is gnutls_x509_crl_print.
258 ** New API to extract signature value from CRL's.
259 The function is gnutls_x509_crl_get_signature.
261 ** Support for directoryName Subject Alternative Name's.
262 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
263 string in the provided buffer.
265 ** Internal improvements to certtool.
266 It uses gnutls_x509_crl_print to print CRL information. It uses some
267 more gnulib modules to simplify error handling.
269 ** API and ABI modifications:
270 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
271 gnutls_supplemental_data_format_type_t: ADD.
272 gnutls_authz_data_format_type_t: ADD.
273 gnutls_supplemental_get_name: ADD.
274 gnutls_authz_recv_callback_func,
275 gnutls_authz_send_callback_func: ADD, callback prototypes.
276 gnutls_authz_enable: ADD.
277 gnutls_authz_send_x509_attr_cert,
278 gnutls_authz_send_saml_assertion,
279 gnutls_authz_send_x509_attr_cert_url,
280 gnutls_authz_send_saml_assertion_url: ADD.
281 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
282 gnutls_x509_crl_print: ADD.
283 gnutls_x509_crl_get_signature: ADD.
285 * Version 1.7.6 (released 2007-02-12)
287 ** Support for 'otherName' Subject Alternative Names.
288 The existing API gnutls_x509_crt_get_subject_alt_name may now return
289 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
290 To find out the otherName OID (necessary for proper parsing of the
291 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
292 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
293 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
294 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
296 ** Certtool can print otherName SAN values for certificates.
297 For known otherName OIDs (currently only id-on-xmppAddr as defined by
298 RFC 3920), it will also print the name.
300 ** Fix TLS 1.2 RSA signing in servers.
301 Before it used the old-style MD5+SHA1 signature, but the TLS
302 signatures should be normal PKCS#1 signatures. FYI, we use and
303 require that DigestInfo parameters are present and NULL for TLS 1.2.
305 ** Add APIs to access X.509 extensions sequentially.
306 The existing APIs gnutls_x509_crt_get_extension_oid() and
307 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
308 inspect the extensions in the order defined by the certificate.
310 ** Add API to extract signature value from X.509 certificates.
311 The function is gnutls_x509_crt_get_signature.
313 ** Fix crash when generating proxy certificates in batch mode.
314 If you don't specify a proxy policy in batch mode, it will use
317 ** Add API to print information about X.509 certificates.
318 The function is gnutls_x509_crt_print.
320 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
321 One consequence of this is that the output syntax has changed
322 slightly. Some more fields are printed.
326 ** API and ABI modifications:
327 gnutls_x509_crt_print: ADD
328 gnutls_certificate_print_formats_t: ADD, new enum.
329 gnutls_x509_crt_get_signature: ADD.
330 gnutls_x509_crt_get_extension_data: ADD.
331 gnutls_x509_crt_get_extension_info: ADD.
332 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
333 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
334 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
336 * Version 1.7.5 (released 2007-02-06)
338 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
341 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
343 ** Fix --list output for gnutls-cli and gnutls-serv.
344 Mention TLS1.2, SHA512 etc.
346 ** Manual contains new section on setting up a test HTTP server.
347 A server set up following those descriptions are available online via
348 <http://www.gnutls.org/server.html>.
350 ** Update of gnulib files.
352 ** API and ABI modifications:
353 No changes since last version.
355 * Version 1.7.4 (released 2007-02-05)
357 ** Support for RSA signing using SHA-256/384/512.
358 A new self test "sha2" tries to build a long X.509 certificate chain
359 testing all new hashes.
361 ** The gnutls-serv tool now use static DH parameters if none are supplied.
363 ** Discuss proxy certificates in the manual.
365 ** Improve bibliographical citations in the manual.
367 ** Update of gnulib files.
369 ** Fix certtool template handling of pathLenConstraints.
370 It now defaults to -1 instead of 0, which causes the field to be
371 missing unless the template specify it.
373 ** API and ABI modifications:
376 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
379 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
380 GNUTLS_SIGN_RSA_SHA256,
381 GNUTLS_SIGN_RSA_SHA384,
382 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
384 * Version 1.7.3 (released 2007-02-01)
386 ** New option to certtool: --generate-proxy.
387 This will generate a Proxy Certificate from an end entity certificate.
388 Proxy Certificates are documented in RFC 3820. You will need to
389 specify the proxy certificate's private key with --load-privkey, the
390 user certificate with --load-certificate and the private key used to
391 sign the new proxy certificate with --load-ca-privkey. Certtool will
392 query for proxy path length and the policy language OID. Currently
393 only OIDs that have an empty policy are supported (which includes the
394 two OIDs defined by RFC 3820).
396 ** Certtool --certificate-info now prints information for Proxy Certificates.
397 Before the proxy extension was just printed as DER encoded data.
399 ** New APIs to set proxy subject names and get/set proxy cert extension.
401 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
403 ** Added self-test to test for regressions of pathLenConstraint bug.
404 Incidentally, this also test (some) other regressions or changes in
405 the output from certtool --certificate-info.
407 ** When certtool generates CA certificates, pressing enter on the path
408 ** length constraint query will now remove the field.
409 Before it set the path length constraint to 0, which is a rather poor
412 ** Certtool now print times in UTC when printing certificate/CRL info.
414 ** Add better fix to work around C++ compiler bug on Mac OS X.
415 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
417 ** Fix import of ASCII armored OpenPGP keys.
418 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
420 ** Update of gnulib files.
422 ** API and ABI modifications:
423 gnutls_x509_crt_set_proxy_dn: ADD.
424 gnutls_x509_crt_set_proxy: ADD.
425 gnutls_x509_crt_get_proxy: ADD.
427 * Version 1.7.2 (released 2007-01-14)
429 ** Certtool now print the value of the pathLenConstraints field for certs.
431 ** Certtool now query for path length constraints when generating CA certs.
432 For batch uses, the certtool configuration name is "path_len".
433 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
435 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
436 The new functions gnutls_x509_crt_get_basic_constraints and
437 gnutls_x509_crt_set_basic_constraints provide a superset of the
438 functionality in the old gnutls_x509_crt_get_ca_status and
439 gnutls_x509_crt_set_ca_status (respectively), but the old functions
440 will continue to be supported.
442 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
443 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
444 OpenCDK release with this patch will be made soon, which should bump
445 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
447 ** Certtool --to-p12 can now store more than one certificate in the blob.
448 Before it could only store one certificate, but now it will read and
449 store as many certificate there are from the --load-certificate file.
450 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
452 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
453 In particular, the OpenPGP function variables are no longer part of
454 the exported libgnutls interface, and no header files from
455 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
456 were never intended for non-internal purposes, and thus this does not
457 imply a change in the external API/ABI.
459 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
460 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
462 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
463 Before these parameters were set to make GnuTLS build under mingw32,
464 however, they appear to no longer be necessary.
466 ** A minor fix to the C++ library to make it build.
467 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
469 ** Update of gnulib files.
471 ** API and ABI modifications:
472 gnutls_x509_crt_get_basic_constraints: ADD.
473 gnutls_x509_crt_set_basic_constraints: ADD.
474 cdk_pubkey_to_sexp: ADD (in opencdk).
475 cdk_seckey_to_sexp: ADD (in opencdk).
477 * Version 1.7.1 (released 2006-12-28)
479 ** TLS 1.2 server side fix.
480 The Certificate Request sent did not contain the list of supported
481 hashes field, thus violating the protocol. It will now contain an
482 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
484 ** TLS 1.2 DSA signature verification fix.
485 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
487 ** Fix the list of trusted CAs that server's send to clients.
488 Before, the list contained issuer DN's instead of subject DN's of the
489 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
491 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
492 Also added a self-test in tests/certificate_set_x509_crl.c to test the
493 function. Reported by Max Kellermann <max@duempel.org>.
495 ** Encode UID fields in DN's as DirectoryString.
496 Before GnuTLS encoded and parsed UID fields as IA5String. This was
497 incorrect, it should have used DirectoryString. Now it will use
498 DirectoryString for the UID field, but for backwards compatibility it
499 will also accept IA5String UID's. Reported by Max Kellermann
502 ** Improve out-of-sourcedir builds from CVS.
503 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
505 ** Bootstrap tools changed.
506 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
507 building GnuTLS from CVS. Libtool 1.5.22 is used.
509 ** Fixed a syntax error in lib/gnutls.asn.
510 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
512 ** Added German translation of GnuTLS messages.
514 ** Update of gnulib files.
516 ** API and ABI modifications:
517 No changes since last version.
519 * Version 1.7.0 (released 2006-11-29)
521 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
522 The details is that the protocol priority set by
523 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
524 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
526 ** Preliminary support for TLS 1.2.
527 The client has been successfully tested against
528 https://www.mikestoolbox.org:4433/.
530 ** Anonself test now print a lot of debugging info, including TLS version.
532 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
534 ** Update of gnulib files.
536 ** API and ABI modifications:
537 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
539 *** Pulled up from stable 1.6.x branch:
541 ** Fix ./configure failure with non-GCC compilers.
542 This fixes the following error message:
543 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
544 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
546 * Version 1.6.1 (released 2006-12-28)
548 ** Fix the list of trusted CAs that server's send to clients.
549 Before, the list contained issuer DN's instead of subject DN's of the
550 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
552 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
553 Reported by Max Kellermann <max@duempel.org>.
555 ** Encode UID fields in DN's as DirectoryString.
556 Before GnuTLS encoded and parsed UID fields as IA5String. This was
557 incorrect, it should have used DirectoryString. Now it will use
558 DirectoryString for the UID field, but for backwards compatibility it
559 will also accept IA5String UID's. Reported by Max Kellermann
562 ** Fix ./configure failure with non-GCC compilers.
563 This fixes the following error message:
564 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
565 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
567 ** API and ABI modifications:
568 No changes since last version.
570 * Version 1.6.0 (released 2006-11-17)
572 ** No changes since 1.5.5.
573 The major changes compared to the 1.4.x branch are:
575 *** A GnuTLS C++ library is part of the official distribution.
576 Currently there are no examples or documentation, but hopefully this
577 will change. See gnutlsxx.h for the API.
579 *** Windows is a supported platform.
580 There are, however, two know bugs. One is related to select() in
581 command line tools (not, nota bene, in the library), the other is a
582 problem with libgcrypt that causes delays. Help is needed to resolve
583 those issues, so we feel we can't delay the release because of this.
585 *** New APIs for custom push/pull function error reporting.
586 The new APIs are gnutls_transport_set_errno and
587 gnutls_transport_set_global_errno. See the release notes for version
588 1.5.4 for more information.
590 *** Self tests are run under valgrind, if available. See --disable-valgrind.
592 * Version 1.5.5 (released 2006-11-16)
594 ** Correctly bump shared library version after adding new APIs.
595 This was forgotten in the last release.
597 ** Fix unsigned vs signed problem in ex-x509-info.c example.
598 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
600 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
602 ** Update of gnulib files.
604 ** API and ABI modifications:
605 No changes since last version.
607 * Version 1.5.4 (released 2006-11-07)
609 ** New API functions to set errno in push/pull functions.
610 Under Windows, setting the errno variable in a push/pull replacement
611 may end up setting the wrong errno variable, and GnuTLS send/recv
612 functions become confused about the real errno returned from a failed
613 push/pull function. Therefor, we have added two APIs to set the errno
614 variable used by GnuTLS. The APIs can also help to keep things
615 thread-safe, by avoiding potentially global variables. Typically,
616 instead of setting errno in your push/pull function, you will call one
617 of these functions. It is recommended to use
618 gnutls_transport_set_errno, but if you don't have the session variable
619 easily accessible in the push/pull replacement function, you can use
620 gnutls_transport_set_global_errno. Suggested by Tim Kosse
621 <tim.kosse@filezilla-project.org>.
623 void gnutls_transport_set_errno (gnutls_session_t session, int err);
624 void gnutls_transport_set_global_errno (int err);
626 ** When calling `recv' or `send' Windows errors are handled properly.
627 The Windows recv/send functions doesn't use errno, and GnuTLS now use
628 WSAGetLastError to access the error condition instead.
630 ** Several OpenPGP API fixes.
631 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
632 important fix is to change the return value of
633 gnutls_openpgp_privkey_get_pk_algorithm and
634 gnutls_openpgp_key_get_pk_algorithm from 'int' to
635 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
636 compatible with 'int').
638 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
639 ** version, try to negotiate the highest version support by the GnuTLS server,
640 ** instead of the lowest.
641 Reported by <Pasi.Eronen@nokia.com>.
643 ** Replace old constructs with use of gnulib modules.
644 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
645 the code. If the headers doesn't exist on the target system, gnulib
646 will make sure its replacement header files are used instead.
648 ** Fix SOVERSION computation for *.def files.
649 This fixes build errors similar to "No rule to make target
650 `libgnutls-`expr', needed by `all-am'." when building for Windows.
652 ** gnutls_check-version uses strverscmp from gnulib.
654 ** Update of gnulib files.
656 ** API and ABI modifications:
657 gnutls_transport_set_errno: ADD
658 gnutls_transport_set_global_errno: ADD
660 * Version 1.5.3 (released 2006-10-26)
662 ** Add new self-test of RSA-MD5 signature chains.
663 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
664 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
665 and is based on the work by Marc Stevens et al, see
666 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
668 ** Re-factor self tests.
670 ** The include copy of Libtasn1 is updated to version 0.3.7.
672 ** The included copy of OpenCDK is updated to version 0.5.11.
674 ** Fix the filename of the *.def file on Windows after library version bump.
676 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
677 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
678 gnulib modules. Earlier we could only use the LGPL'ed module from
679 gnulib, because two gnulib directories in the same project didn't
682 ** API and ABI modifications:
683 No changes since last version.
685 * Version 1.5.2 (released 2006-10-03)
687 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
688 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
689 shared library version than this version, so you'll have to remove
690 them and possibly relink your applications. The reason for this is
691 that no API/ABI changes have been made since the 1.4.x branch, and
692 that incrementing the shared library version was a mistake. Reported
693 by Andreas Metzler <ametzler@downhill.at.eu.org>.
695 ** Fix off-by-one error when computing length to malloc.
696 The code is used by gnutls_openpgp_add_keyring_file and
697 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
698 <agl@imperialviolet.org>.
700 ** Add version script for the GnuTLS C++ library.
701 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
703 ** Fix the C++ compiler detection logic.
704 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
706 ** Update of gnulib files.
708 ** API and ABI modifications:
709 No changes since last version.
711 * Version 1.5.1 (released 2006-09-21)
713 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
714 ** Crypto 06 rump session attack.
715 In particular, we check that the digestAlgorithm.parameters field is
716 missing or empty, to avoid that it can contain "garbage" that may be
717 used to alter the numeric properties of the signature. See
718 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
719 not exactly the same as the problem we fix here). Reported by Yutaka
720 OIWA <y.oiwa@aist.go.jp>.
722 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
723 up to date information.
725 ** Add self test to test for above flaw.
727 ** Fix gnutls-cli-debug regarding resume support detection.
728 Earlier, if the session-id from the server had a length of 0, it would
729 indicate the the server supports resumption, which isn't the case.
730 Reported by Kataja Kai <kai.kataja@op.fi>.
732 ** Fix building of examples on FreeBSD by including netinet/in.h.
733 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
735 ** Fix certtool bug that caused the private key to not be loaded when
736 generating a certificate with --load-request, which in turn triggered
737 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
738 by Sascha Ziemann <sascha.ziemann@secunet.com>.
740 ** gnutls-cli and gnutls-serv works on Windows.
741 The problem was the select() call that doesn't work on file
742 descriptors (stdin) on Windows. We borrowed some code from plibc to
743 solve this. It appears to be somewhat unreliable though.
745 ** Autoconf 2.60 is now used.
747 ** API and ABI modifications:
748 No changes since last version.
750 * Version 1.5.0 (released 2006-08-13)
752 ** Change SRP and Cert-Type extensions to match IANA registry.
754 ** Fixed bug in OpenPGP authentication handshake.
756 ** Improvements for building under MinGW.
757 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
758 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
759 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
760 at run-time from ws2_32.dll, and falls back on a simple replacement if
761 it is not available. Builds the library with -mms-bitfields
762 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
763 create *.def files, which are installed.
765 ** The examples now (conditionally) include config.h and link to gnulib.
766 No other source changes were necessary, so the examples should
767 continue to be possible to use stand-alone without any autoconf or
770 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
771 You may unconditionally disable it with --disable-cxx. See
772 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
775 ** Made command line tool '--version' behave according to GNU Standards.
776 This enables 'make distcheck' to succeed.
778 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
780 ** Make --without-included-libtasn1 work.
781 Reported by Daniel Black <dragonheart@gentoo.org>.
783 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
784 See http://www.gnu.org/software/gnutls/security.html regardging

786 satyakumar <satyam_kkd@hyd.hellosoft.com>.
788 ** API and ABI modifications:
789 No changes since last version.
791 * Version 1.4.5 (released 2006-11-06)
793 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
794 ** version, try to negotiate the highest version support by the GnuTLS server,
795 ** instead of the lowest.
796 Reported by <Pasi.Eronen@nokia.com>.

799 Reported by Adam Langley" <agl@imperialviolet.org>.
801 ** API and ABI modifications:
802 No changes since last version.
804 * Version 1.4.4 (released 2006-09-12)
806 ** Relax the test that caught signatures that exploit the variant of
807 ** Bleichenbacher's Crypto 06 rump session attack on our
808 ** verification logic flaw.
809 In particular, we now permit the digestAlgorithm.parameters field to
810 be present but empty, whereas in 1.4.3 we actually checked that the
813 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
814 The messages are only printed in debug mode, which is not recommended
815 for normal use, and thus logging this situation cannot be abused as an
816 oracle in typical recommended situations.
818 ** API and ABI modifications:
819 No changes since last version.
821 * Version 1.4.3 (released 2006-09-08)
823 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
824 ** Crypto 06 rump session attack.
825 In particular, we check that the digestAlgorithm.parameters field is
826 empty, to avoid that it can contain "garbage" that may be used to
827 alter the numeric properties of the signature. See

835 ** Fix PKCS#1 decryption to avoid Bleichenbacher's Crypto 98 attack.
836 See <http://www.bell-labs.com/user/bleichen/papers/pkcs.ps.gz>.
837 Reported by Werner Koch <wk@gnupg.org>.
839 See GNUTLS-SA-2006-3 on http://www.gnutls.org/security.html for more

842 ** Fix crash in gnutls_x509_crt_sign2 if passed a NULL issuer_key.
844 ** API and ABI modifications:
845 No changes since last version.
847 * Version 1.4.2 (released 2006-08-12)
849 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
850 This can happen if you call gnutls_certificate_verify_peers2 and have
851 a certain mix of local CA certificates and the peer send special
852 certificates, that together trigger certain behaviour. It is not
853 known at this point whether the crash can be triggered without the
854 special local CA certificate, and thus turn this into a remote crash
855 of clients that verify server certificates when they talk to a server
856 with the special server certificate. See GNUTLS-SA-2006-2 on
857 http://www.gnu.org/software/gnutls/security.html for more up to date
858 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
860 ** Change SRP and Cert-Type extensions to match IANA registry.
862 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
864 ** Make --without-included-libtasn1 work.
865 Reported by Daniel Black <dragonheart@gentoo.org>.
867 ** API and ABI modifications:
868 No changes since last version.
870 * Version 1.4.1 (released 2006-06-14)
872 ** Replaced inactive ifdefs to enable openpgp support in test programs.
874 ** Fixed bug in OpenPGP authentication handshake.
876 ** Fixed typographical in man pages.
878 ** Build fixes of the manual.
880 ** Added Swedish translation.
882 ** API and ABI modifications:
883 No changes since last version.
885 * Version 1.4.0 (released 2006-05-15)
887 ** Remove GnuTLS 0.8.x compatibility functions.
889 ** The libgcrypt RNG is initialized in gnutls_global_init().
891 ** TLS/IA API changes from Emile van Bergen.
892 A dummy credential structure is not needed now, if you wish to use the
893 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
896 ** The self-tests are now run under valgrind, if it is installed.
898 ** Libtasn1 is updated to 0.3.4, and that version is now required.
900 ** The command line tools now use getaddrinfo and support IPv6.
902 ** API and ABI modifications:
903 _gnutls_x509_get_raw_crt_activation_time,
904 _gnutls_x509_get_raw_crt_expiration_time: Removed.
905 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
906 gnutls_ia_enable: Added.
908 * Version 1.3.5 (released 2006-03-08)
910 ** Error messages are now translated using GNU Gettext.
912 ** The function gnutls_x509_crt_to_xml now return an internal error.
913 This means that the code to convert X.509 certificates to XML format
914 does not work any more. The reason is that the function called
915 libtasn1 internal functions. It seems unclean for libtasn1 to export
916 the APIs needed here. Instead it would be better to implement XML
917 support inside libtasn1 properly. If you need this functionality
918 strongly, please consider looking into implementing this suggested
919 approach instead. As a workaround, you may also modify lib/x509/xml.c
920 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
922 ** Libraries are now built with libtool's -no-undefined.
923 This helps producing libraries for Windows using mingw32.
925 ** Doc fixes to explain that gnutls_record_send can block.
927 ** Libtasn1 0.3.1 or later is now required.
928 The include copy has been updated too.
930 ** gnutls-cli can now recognize services and port numbers with the -p option.
932 ** API and ABI modifications:
933 No changes since last version.
935 * Version 1.3.4 (released 2006-02-09)
937 ** Fix read of out bounds bug in DER parser.
938 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
939 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
940 previous bug fix. The included libtasn1 version in GnuTLS has been
943 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
944 longer invalidate a session if the underlying send fails, but it will
945 prevent future writes. That is to allow reading the already received data.
946 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
948 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
949 gnutls_certificate_set_x509_trust(), that caused memory corruption if
950 more than one certificates were added. Report and patch by Max Kellermann.
952 ** Fix build problems of OpenCDK on AIX.
953 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
955 ** API and ABI modifications:
956 No changes since last version.
958 * Version 1.3.3 (released 2006-01-12)
960 ** New API to access the TLS master secret.
961 When possible, you should use the TLS PRF functions instead.
962 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
964 ** Improved handling when multiple libraries use GnuTLS at the same time.
965 Now gnutls_global_init() can be called multiple times, and
966 gnutls_global_deinit() will only deallocate the structure when it has
967 been called as many times as gnutls_global_init() was called.
969 ** Added a self test of TLS resume functionality.
971 ** Fix crash in TLS resume code, caused by TLS/IA changes.
973 ** Documentation fixes about thread unsafety, prompted by
974 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
975 In particular, gnutls_global_init() and gnutls_global_deinit() are not
976 thread safe. Careful callers may want to protect the call using a
977 mutex. The problem could also be ignored, which would cause a memory
978 leak under rare conditions when two threads invoke the function
979 roughly at the same time.
981 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
983 ** The code was indented again, including the external header files.
985 ** API and ABI modifications:
986 New functions to retrieve the master secret value:
987 gnutls_session_get_master_secret
989 Add a 'const' keyword to existing API:
990 gnutls_x509_crq_get_challenge_password
992 * Version 1.3.2 (released 2005-12-15)
994 ** GnuTLS now support TLS Inner application (TLS/IA).
995 This is per draft-funk-tls-inner-application-extension-01. This
996 functionality is added to libgnutls-extra, so it is licensed under the
997 GNU General Public License.
999 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
1000 The PRF is used by some protocols building on TLS, such as EAP-PEAP
1001 and EAP-TTLS. One function to access the raw PRF and one to access
1002 the PRF seeded with the client/server random fields are provided.
1003 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
1005 ** New APIs to acceess the client and server random fields in a session.
1006 These fields can be useful by protocols using TLS. Note that these
1007 fields are typically used as input to the TLS PRF, and if this is your
1008 intended use, you should use the TLS PRF API that use the
1009 client/server random field directly. Suggested by Jouni Malinen
1010 <jkmaline@cc.hut.fi>.
1012 ** Internal type cleanups.
1013 The uint8, uint16, uint32 types have been replaced by uint8_t,
1014 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
1015 correct types on platforms that lack them. The uint type have been
1016 replaced by unsigned.
1018 ** API and ABI modifications:
1019 New functions to invoke the TLS Pseudo-Random-Function (PRF):
1023 New functions to retrieve the session's client and server random values:
1024 gnutls_session_get_server_random
1025 gnutls_session_get_client_random
1027 New function, to perform TLS/IA handshake:
1030 New function to decide whether to do a TLS/IA handshake:
1031 gnutls_ia_handshake_p
1033 New functions to allocate a TLS/IA credential:
1034 gnutls_ia_allocate_client_credentials
1035 gnutls_ia_free_client_credentials
1036 gnutls_ia_allocate_server_credentials
1037 gnutls_ia_free_server_credentials
1039 New functions to handle the AVP callback:
1040 gnutls_ia_set_client_avp_function
1041 gnutls_ia_set_client_avp_ptr
1042 gnutls_ia_get_client_avp_ptr
1043 gnutls_ia_set_server_avp_function
1044 gnutls_ia_set_server_avp_ptr
1045 gnutls_ia_get_server_avp_ptr
1047 New functions, to toggle TLS/IA application phases:
1048 gnutls_ia_require_inner_phase
1050 New function to mix session keys with inner secret:
1051 gnutls_ia_permute_inner_secret
1053 Low-level API (used internally by gnutls_ia_handshake):
1054 gnutls_ia_endphase_send
1058 New functions that can be used after successful TLS/IA negotiation:
1059 gnutls_ia_generate_challenge
1060 gnutls_ia_extract_inner_secret
1062 Enum type with TLS/IA modes:
1065 Enum type with TLS/IA packet types:
1068 Enum values for TLS/IA alerts:
1069 GNUTLS_A_INNER_APPLICATION_FAILURE
1070 GNUTLS_A_INNER_APPLICATION_VERIFICATION
1072 New error codes, to signal when an application phase has finished:
1073 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
1074 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
1076 New error code to signal TLS/IA verify failure:
1077 GNUTLS_E_IA_VERIFY_FAILED
1079 * Version 1.3.1 (released 2005-12-08)
1081 ** Support for DHE-PSK cipher suites has been added.
1082 This method offers perfect forward secrecy.
1084 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
1085 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
1087 ** Corrected a bug in certtool for 64 bit machines. Reported
1088 by Max Kellermann <max@duempel.org>.
1090 ** New function to set a X.509 private key and certificate pairs, and/or
1091 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
1092 <emile@e-advies.nl>.
1094 The integrity of the PKCS#12 file is protected through a password
1095 based MAC; public-key based signatures for integrity protection are
1096 not supported. PKCS#12 bags may be encrypted using password derived
1097 symmetric keys, public-key based encryption is not supported. The
1098 PKCS#8 keys may be encrypted using passwords. The API use the same
1099 password for all operations. We believe that any more flexibility
1100 create too much complexity that would hurt overall security, but may
1101 add more PKCS#12 related APIs if real-world experience indicate
1104 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
1105 reported by Emile van Bergen <emile@e-advies.nl>.
1106 This will enable "certtool -k -8" to parse those keys.
1108 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
1109 Use "certtool -p -8" and press press enter at the prompt. Earlier,
1110 certtool would have encrypted the key using an empty password.
1112 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
1113 Earlier it would have prompted the user for it, even if --password was
1116 ** Added self test of PKCS#8 parsing.
1117 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
1118 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in

1131 New API to set PSK Diffie-Hellman parameters:
1132 gnutls_psk_set_server_dh_params
1134 * Version 1.3.0 (2005-11-15)
1136 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
1137 This add several new APIs, see below. Read the updated manual for
1138 more information. A new self test "pskself" has been added, that will
1139 test this functionality.
1141 ** The session resumption data are now system independent.
1143 ** The code has been re-indented to conform to the GNU coding style.

1200 * Version 1.2.11 (2006-05-11)
1201 - The function gnutls_x509_crt_to_xml is not supported any more, and
1202 return an internal error. The reason is that the function called
1203 internal libtasn1 functions which are no longer exported from
1205 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
1206 - Updated gnulib compatibility files.
1207 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
1208 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
1209 - API and ABI modifications:
1210 No changes since last version.
1212 * Version 1.2.10 (2006-02-09)
1213 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
1214 <admin@gleg.net>, and debugging help from Protover SSL.
1215 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
1216 The included version has been updated too.
1217 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
1218 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
1219 - Corrected a bug in certtool for 64 bit machines. Reported
1220 by Max Kellermann <max@duempel.org>.
1221 - Corrected bugs in gnutls_certificate_set_x509_crl() and
1222 gnutls_certificate_set_x509_trust(), that caused memory corruption if
1223 more than one certificates were added. Report and patch by Max Kellermann.
1224 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
1225 longer invalidate a session if the underlying send fails, but it will
1226 prevent future writes. That is to allow reading the already received data.
1227 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
1229 * Version 1.2.9 (2005-11-07)
1230 - Documentation was updated and improved.
1231 - RSA-MD2 is now supported for verifying digital signatures.
1232 - Due to cryptographic advances, verifying untrusted X.509
1233 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
1234 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
1235 applications that must remain interoperable, you can use the
1236 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
1237 flags when verifying certificates. Naturally, this is not
1238 recommended default behaviour for applications. To enable the
1239 broken algorithms, call gnutls_certificate_set_verify_flags with the
1240 proper flag, to change the verification mode used by
1241 gnutls_certificate_verify_peers2.
1242 - Make it possible to send empty data through gnutls_record_send,
1243 to align with the send(2) API.
1244 - Some changes in the certificate receiving part of handshake to prevent
1245 some possible errors with non-blocking servers.
1246 - Added numeric version symbols to permit simple CPP-based feature
1247 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
1248 - The (experimental) low-level crypto alternative to libgcrypt used
1249 earlier (Nettle) has been replaced with crypto code from gnulib.
1250 This leads to easier re-use of these components in other projects,
1251 leading to more review and simpler maintenance. The new configure
1252 parameter --with-builtin-crypto replace the old --with-nettle, and
1253 must be used if you wish to enable this functionality. See README
1254 under "Experimental" for more information. Internally, GnuTLS has
1255 been updated to use the new "Generic Crypto" API in gl/gc.h. The
1256 API is similar to the old crypto/gc.h, because the gnulib code were
1257 based on GnuTLS's gc.h.
1258 - Fix compiler warning in the "anonself" self test.
1259 - API and ABI modifications:
1260 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
1261 This doesn't reflect a change in behaviour,
1262 so we don't break backwards compatibility.
1263 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
1264 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
1265 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
1266 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
1268 gnutls_x509_crt_list_verify,
1269 gnutls_x509_crt_verify, or
1270 gnutls_certificate_set_verify_flags.
1271 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
1272 used when broken signature algorithms
1273 is used (currently RSA-MD2/MD5).
1274 LIBGNUTLS_VERSION_MAJOR,
1275 LIBGNUTLS_VERSION_MINOR,
1276 LIBGNUTLS_VERSION_PATCH,
1277 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
1278 version number, can be used for feature existence
1281 * Version 1.2.8 (2005-10-07)
1282 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
1283 - Don't install the auxilliary libexamples library used by the
1284 examples in doc/examples/ on "make install", report and tiny patch
1285 from Thomas Klausner <tk@giga.or.at>.
1286 - If you pass a X.509 CA or PGP trust database to the command line
1287 tool, it will now abort the connection if the server certificate
1288 validation fails. Use the parameter --insecure to continue even
1289 after certificate validation failures. Inspired from discussion
1290 with Alexander Kotelnikov <sacha@myxomop.com>.
1291 - The test for socklen_t has been moved to gnulib.

1353 - Introduced the --fix-key option to certtool, which can be used to
1354 regenerate the (optional) parameters in a private key. It should
1355 be used together with --key-info.

1378 and made source code include external include file, to check
1379 function prototypes during compile time.
1380 - API and ABI modifications:
1381 No changes since last version. At least not intentional, but due
1382 to the include header changes, there may be inadvertant changes,
1383 please let us know if you find any.

1390 - Added warning to certtool when MD5 is being used for digital
1392 - Optimizations ("-O2 -finline-functions") are not enabled by default,
1393 instead the standard autoconf defaults are used. Use `./configure
1394 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
1395 - Added the option --get-dh-params to certtool, in order to get the
1396 parameters included in the library primes and generators.

1432 gnutls_x509_rdn_get now set *sizeof_buf to the buffer length that is
1433 required, instead of the string length. That is, the value has been
1434 incremented by 1 to account for the terminating zero. Reported by
1435 Martin Lambers <marlam@web.de>.
1436 - Debug output shouldn't crash on platforms that doesn't handle NULL
