** libgnutls: Allow ECC when in SSL 3.0 to work-around a bug in certain
openssl versions.

** libgnutls: Fixes in interrupted function resumption. Report
and patch by Tim Kosse.

** libgnutls: Corrected issue when receiving client hello verify requests
in DTLS.

** libgnutls: Fixes in DTLS record overhead size calculations.

As they are not standardized they are defined using private ciphersuite
numbers.

** libgnutls: Added support for DTLS 1.2.

** libgnutls: Added support for the Application Layer Protocol Negotiation
(ALPN) extension.

** libgnutls: Removed support for the RSA-EXPORT ciphersuites.

** libgnutls: Avoid linking to librt (that also avoids unnecessary

* Version 3.1.7 (released 2013-02-04)

** certtool: Added option "dn" which allows to directly set the DN
in a template from an RFC4514 string.

** danetool: Added options: --dlv and --insecure. Suggested by Paul Wouters.

** libgnutls-xssl: Added a new library to simplify GnuTLS usage.

** libgnutls-dane: Added function to specify a DLV file.

** libgnutls: Heartbeat code was made optional.

** libgnutls: Fixes in server side of DTLS-0.9.

** libgnutls: DN variable 'T' was expanded to 'title'.

** libgnutls: Fixes in record padding parsing to prevent a timing attack.
Issue reported by Kenny Paterson and Nadhem Alfardan.

** libgnutls: Added functions to directly set the DN in a certificate
or request from an RFC4514 string.

** libgnutls: Optimizations in the random generator. The re-seeding of
it is now explicitly done on every session deinit.

** libgnutls: Simplified the DTLS sliding window implementation.

** libgnutls: The minimum DH bits accepted by a client are now set
by the specified priority string. The current values correspond to the
previous defaults (727 bits), except for the SECURE128 and SECURE192
strings which increase the minimum to 1248 and 1776 respectively.

** libgnutls: Added the gnutls_record_cork() and uncork API to enable
buffering in sending application data.

** libgnutls: Removed default random padding, and added a length-hiding interface
instead.  Both the server and the client must support this extension. Whether
length-hiding can be used on a given session can be checked using
gnutls_record_can_use_length_hiding(). Contributed by Alfredo Pironti.

** libgnutls: Added the experimental %NEW_PADDING priority string. It enables
a new padding mechanism in TLS allowing arbitrary padding in TLS records
in all ciphersuites, which makes length-hiding more efficient and solves
the issues with timing attacks on CBC ciphersuites.

** libgnutls: Corrected gnutls_cipher_decrypt2() when used with AEAD
ciphers (i.e., AES-GCM). Reported by William McGovern.

instead of issuing an error.

** libgnutls: Stricter RSA PKCS #1 1.5 encoding and decoding. Reported
by Kikuchi Masashi.

** libgnutls: Added functions to parse the certificates policies
extension.

** libgnutls: Handle BMPString (UCS-2) encoding in the Distinguished
Name by translating it to UTF-8 (works on windows or systems with iconv).

** libgnutls: Added PKCS #11 key generation function that returns the
public key on generation.

** libgnutls: Corrected bug in priority string parsing, that mostly
affected combined levels. Patch by Tim Kosse.

** certtool: The --pubkey-info option can be combined with the
--load-privkey or --load-request to print the corresponding public keys.

** certtool: It is able to set certificate policies via a template.

** certtool: Added --hex-numbers option which prints big numbers in
an easier to parse format.

** p11tool: After key generation, outputs the public key (useful in
tokens that do not store the public key).

** danetool: It is being built even without libgnutls-dane (the
--check functionality is disabled though).

** libgnutls: Added verification flag GNUTLS_VERIFY_DO_NOT_ALLOW_UNSORTED_CHAIN
and made GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN the default.

** libgnutls: Always tolerate key usage violation errors from the side
of the peer, but also notify via an audit message.

extension.

** libgnutls: gnutls_certificate_verify_peers2() will use the OCSP
certificate status extension in verification.

** libgnutls: Bug fixes in gnutls_x509_privkey_import_openssl().

** libgnutls: Increased maximum password length in the PKCS #12
functions.

** libgnutls: Fixed the receipt of session tickets during session resumption.

** libgnutls: Added gnutls_ocsp_resp_check_crt() to check whether the OCSP
response corresponds to the given certificate.

** libgnutls: In client side gnutls_init() enables the session ticket and
OCSP certificate status request extensions by default. The flag
GNUTLS_NO_EXTENSIONS can be used to prevent that.

** libgnutls: Several updates in the OpenPGP code. The generating code
is fully RFC6091 compliant and RFC5081 support is only supported in client
mode.

** libgnutls-dane: Added. It is a library to provide DANE with DNSSEC
certificate verification.

** gnutls-cli: Added --dane option to enable DANE certificate verification.

* Version 3.1.2 (released 2012-09-26)

** libgnutls: Fixed bug in gnutls_x509_trust_list_add_system_trust()
and gnutls_x509_trust_list_add_trust_mem() that prevented the loading
of certificates in the windows platform.

** libgnutls: Corrected bug in OpenPGP subpacket encoding.

** libgnutls: Added support for DTLS/TLS heartbeats by Olga Smolenchuk.
(the work was done during Google Summer of Code).

** libgnutls: Added X.509 certificate verification flag
GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN. This flag allows the verification
of unsorted certificate chains and is enabled by default for
TLS certificate verification (if gnutls_certificate_set_verify_flags()
does not override it).

** libgnutls: Prints warning on certificates that contain keys of
an insecure level. If the %COMPAT priority flag is not specified
the TLS connection fails.

** libgnutls: Correctly restore gnutls_record_recv() in DTLS mode
if interrupted during the retrasmition of handshake data.

** libgnutls: Better mingw32 support (patch by LRN).

** libgnutls: The %COMPAT keyword, if specified, will tolerate
key usage violation errors (they are far too common to ignore).

** libgnutls: Added GNUTLS_STATELESS_COMPRESSION flag to gnutls_init(),
which provides a tool to counter compression-related attacks where
parts of the data are controlled by the attacker _and_ are placed in
separate records (use with care - do not use compression if not sure).

** libgnutls: Depends on libtasn1 2.14 or later.

** certtool: Prints the number of bits of the public key algorithm
parameter in a private key.

** API and ABI modifications:
gnutls_x509_privkey_get_pk_algorithm2: Added

* Version 3.1.1 (released 2012-09-02)

** gnutls-serv: Listens on IPv6. Patch by Bernhard R. Link.

** certtool: Changes in password handling of certtool.
Ask password when required and only if the '--password' option is not
given. If the '--password' option is given during key generation then
assume the PKCS #8 file format, instead of ignoring the password.

** tpmtool: No longer asks for key password in registered keys.

** libgnutls: Elliptic curve code was optimized by Ilya Tumaykin.
wmNAF is now used for point multiplication and other optimizations.
(the major part of the work was done during Google Summer of Code).

** libgnutls: The default pull_timeout_function only uses select
instead of a combination of select() and recv() to prevent issues
when used in stream sockets in some systems.

** libgnutls: Be tolerant in ECDSA signature violations (e.g. using
SHA256 with a SECP384 curve instead of SHA-384), to interoperate with
openssl.

** libgnutls: Fixed DSA and ECDSA signature generation in smart
cards. Thanks to Andreas Schwier from cardcontact.de for providing
me with ECDSA capable smart cards.

** API and ABI modifications:
gnutls_sign_algorithm_get: Added
gnutls_sign_get_hash_algorithm: Added
gnutls_sign_get_pk_algorithm: Added

* Version 3.1.0 (released 2012-08-15)

** libgnutls: Added direct support for TPM as a cryptographic module
in gnutls/tpm.h. TPM keys can be used in functions accepting files
using URLs of the following types:
  tpmkey:file=/path/to/file
  tpmkey:uuid=7f468c16-cb7f-11e1-824d-b3a4f4b20343;storage=user

** libgnutls: Priority string level keywords can be combined.
For example the string "SECURE256:+SUITEB128" is now allowed.

** libgnutls: requires libnettle 2.5.

** libgnutls: Use the PKCS #1 1.5 encoding provided by nettle (2.5)
for encryption and signatures.

** libgnutls: Added GNUTLS_CERT_SIGNATURE_FAILURE to differentiate between
generic errors and signature verification errors in the verification
functions.

** libgnutls: Added gnutls_pkcs12_simple_parse() as a helper function
to simplify parsing in most PKCS #12 use cases.

** libgnutls: gnutls_certificate_set_x509_simple_pkcs12_file() adds
the whole certificate chain (if any) to the credentials structure, instead
of only the end-user certificate.

** libgnutls: Key import functions such as gnutls_pkcs12_simple_parse()
and gnutls_x509_privkey_import_pkcs8(), return consistently
GNUTLS_E_DECRYPTION_FAILED if the input structure is encrypted but no
password was provided.

** libgnutls: Added gnutls_handshake_set_timeout() a function that
allows to set the maximum time spent in a handshake.

** libgnutlsxx: Added session::set_transport_vec_push_function. Patch
by Alexandre Bique.

** tpmtool: Added. It is a tool to generate private keys in the
TPM.

** gnutls-cli: --benchmark-tls was split to --benchmark-tls-kx
and --benchmark-tls-ciphers

** certtool: generated PKCS #12 structures may hold more than one
private key. Patch by Lucas Fisher.

** certtool: Added option --null-password to generate/decrypt keys
that use a NULL password (in schemas that distinguish between NULL
an empty passwords).

** minitasn1: Upgraded to libtasn1 version 2.13.
