We are pleased to announce the availability of a new stable GnuPG-2
release: Version 2.0.1

This is maintenance release to fix build problems found after the
release of 2.0.0 and to fix a buffer overflow in gpg2

The GNU Privacy Guard (GnuPG) is GNU's tool for secure communication
and data storage.  It can be used to encrypt data, create digital
signatures, help authenticating using Secure Shell and to provide a
framework for public key cryptography.  It includes an advanced key
management facility and is compliant with the OpenPGP and S/MIME

GnuPG-2 has a different architecture than GnuPG-1 (e.g. 1.4.5) in that
it splits up functionality into several modules.  However, both
versions may be installed alongside without any conflict.  In fact,
the gpg version from GnuPG-1 is able to make use of the gpg-agent as
included in GnuPG-2 and allows for seamless passphrase caching.  The
advantage of GnuPG-1 is its smaller size and the lack of dependency on
other modules at run and build time.  We will keep maintaining GnuPG-1
versions because they are very useful for small systems and for server
based applications requiring only OpenPGP support.

GnuPG is distributed under the terms of the GNU General Public License
(GPL).  GnuPG-2 works best on GNU/Linux or *BSD systems.  A port
Windows is planned but work has not yet started.

Getting the Software

Please follow the instructions found at http://www.gnupg.org/download/
or read on:

GnuPG 2.0.1 may be downloaded from one of the GnuPG mirror sites or
direct from ftp://ftp.gnupg.org/gcrypt/ .  The list of mirrors can be
found at http://www.gnupg.org/mirrors.html .  Note, that GnuPG is not
available at ftp.gnu.org.

On the mirrors you should find the following files in the *gnupg*

  gnupg-2.0.1.tar.bz2 (3.8Mk)

      GnuPG source compressed using BZIP2 and OpenPGP signature.

  gnupg-2.0.0-2.0.1.diff.bz2 (220k)

      A patch file to upgrade a 2.0.0 GnuPG source.  This is only that
      large arge due to an update of the included gettext module.

Note, that we don't distribute gzip compressed tarballs.  

Checking the Integrity

In order to check that the version of GnuPG which you are going to
install is an original and unmodified one, you can do it in one of
the following ways:

 * If you already have a trusted version of GnuPG installed, you
   can simply check the supplied signature.  For example to check the
   signature of the file gnupg-2.0.1.tar.bz2 you would use this command:

     gpg --verify gnupg-2.0.1.tar.bz2.sig

   This checks whether the signature file matches the source file.
   You should see a message indicating that the signature is good and
   made by that signing key.  Make sure that you have the right key,
   either by checking the fingerprint of that key with other sources
   or by checking that the key has been signed by a trustworthy other
   key.  Note, that you can retrieve the signing key using the command

     finger wk ,at' g10code.com

   or using a keyserver like

     gpg --recv-key 1CE0C630

   The distribution key 1CE0C630 is signed by the well known key
   5B0358A2.  If you get an key expired message, you should retrieve a
   fresh copy as the expiration date might have been prolonged.


 * If you are not able to use an old version of GnuPG, you have to verify
   the SHA-1 checksum.  Assuming you downloaded the file
   gnupg-2.0.1.tar.bz2, you would run the sha1sum command like this:

     sha1sum gnupg-2.0.1.tar.bz2

   and check that the output matches the first line from the
   following list:

ec84ffb1d2ac013dc0afb5bdf8b9df2c838673e9  gnupg-2.0.1.tar.bz2
c6cca309b12700503bb4c671491ebf7a4cd6f1be  gnupg-2.0.0-2.0.1.diff.bz2

What's New

 * Experimental support for the PIN pads of the SPR 532 and the Kaan
   Advanced card readers.  Add "disable-keypad" scdaemon.conf if you
   don't want it.  Does currently only work for the OpenPGP card and
   its authentication and decrypt keys.

 * Fixed build problems on some some platforms and crashes on amd64.

 * Fixed a buffer overflow in gpg2. [bug#728]


GnuPG comes with support for 27 languages.  Due to a lot of new and
changed strings most translations are not entirely complete. However
the Turkish, German and Russian translators have meanwhile finished
their translations.  Updates of the other translations are expected
for the next releases.


We are currently working on an installation guide to explain in more
detail how to configure the new features.  As of now the chapters on
gpg-agent and gpgsm include brief information on how to set up the
whole thing.  Please watch the GnuPG website for updates of the
documentation.  In the meantime you may search the GnuPG mailing list
archives or ask on the gnupg-users mailing lists for advise on how to
solve problems.  Many of the new features are around for several years
and thus enough public knowledge is already available.


Improving GnuPG is costly, but you can help!  We are looking for
organizations that find GnuPG useful and wish to contribute back.  You
can contribute by reporting bugs, improve the software, or by donating

Commercial support contracts for GnuPG are available, and they help
finance continued maintenance.  g10 Code GmbH, a Duesseldorf based
company owned and headed by GnuPG's principal author, is currently
funding GnuPG development.  We are always looking for interesting
development projects.

We have to thank all the people who helped with this release, be it
testing, coding, translating, suggesting, auditing, administering the
servers, spreading the word or answering questions on the mailing

Happy Hacking,

  The GnuPG Team (David, Werner and all other contributors)
