We are pleased to announce the availability of a new stable GnuPG
release: Version 1.4.2

The GNU Privacy Guard (GnuPG) is GNU's tool for secure communication
and data storage.  It is a complete and free replacement of PGP and
can be used to encrypt data and to create digital signatures.  It
includes an advanced key management facility and is compliant with the
proposed OpenPGP Internet standard as described in RFC2440.

Getting the Software

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

GnuPG 1.4.2 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-1.4.2.tar.bz2 (2.8M)

      GnuPG source compressed using BZIP2 and OpenPGP signature.

  gnupg-1.4.2.tar.gz (4.0M)

      GnuPG source compressed using GZIP and OpenPGP signature.

  gnupg-1.4.1-1.4.2.diff.bz2 (939k)

      A patch file to upgrade a 1.4.1 GnuPG source. 

Select one of them. To shorten the download time, you probably want to
get the BZIP2 compressed file.  Please try another mirror if
exceptional your mirror is not yet up to date.

In the *binary* directory, you should find these files:

  gnupg-w32cli-1.4.2.exe (1.4M)

      GnuPG compiled for Microsoft Windows and OpenPGP signature.
      Note that this is a command line version and now comes with a
      graphical installer tool.  The source files are the same as
      given above.

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-1.4.2.tar.bz2 you would use this command:

     gpg --verify gnupg-1.4.2.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 "finger wk
   'at' g10code.com" or "finger dd9jn 'at' gnu.org" or using the
   keyservers.  From time to time I prolong the expiration date; thus
   you might need a fresh copy of that key.

   Never use a GnuPG version you just downloaded to check the
   integrity of the source - use an existing GnuPG installation!

 * 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-1.4.2.tar.bz2, you would run the sha1sum command like this:

     sha1sum gnupg-1.4.2.tar.bz2

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

6eda5b090f9f1ac0da5e8b545e2667220a0e89ca  gnupg-1.4.2.tar.bz2
cc7e9a5268bf309ac652a7343b62dff8cfb68d38  gnupg-1.4.2.tar.gz
ca0180b5e5d6ee78c68c701f6ded2d9008bf7608  gnupg-1.4.1-1.4.2.diff.bz2
8394920be8d2daa764e94d4bd5869853a3f293b8  gnupg-w32cli-1.4.2.exe

Upgrade Information

If you are upgrading from a version prior to 1.0.7, you should run the
script tools/convert-from-106 once.  Please note also that due to a
bug in versions prior to 1.0.6 it may not be possible to downgrade to
such versions unless you apply the patch
http://www.gnupg.org/developer/gpg-woody-fix.txt .

If you have any problems, please see the FAQ and the mailing list
archive at http://lists.gnupg.org.  Please direct questions to the
gnupg-users at gnupg.org mailing list.

What's New

    * New command "verify" in the card-edit menu to display
      the Private-DO-3.  The Admin command has been enhanced to take
      the optional arguments "on", "off" and "verify".  The latter may
      be used to verify the Admin Pin without modifying data; this
      allows displaying the Private-DO-4 with the "list" command.

    * Rewrote large parts of the card code to optionally make use of a
      running gpg-agent.  If --use-agent is being used and a gpg-agent
      with enabled scdaemon is active, gpg will now divert all card
      operations to that daemon.  This is required because both,
      scdaemon and gpg require exclusive access to the card reader. By
      delegating the work to scdaemon, both can peacefully coexist and
      scdaemon is able to control the use of the reader.  Note that
      this requires at least gnupg 1.9.17.

    * Fixed a couple of problems with the card reader.

    * Command completion is now available in the --edit-key and
      --card-edit menus.  Filename completion is available at all
      filename prompts.  Note that completion is only available if the
      system provides a readline library.

    * New experimental HKP keyserver helper that uses the cURL
      library.  It is enabled via the configure option --with-libcurl
      like the other (also experimental) cURL helpers. Please make
      sure to also apply the attached patch.

    * New key cleaning options that can be used to remove unusable
      (expired, revoked) signatures from a key.  This is available via
      the new "clean" command in --edit-key on a key by key basis, as
      well as via the import-clean-sigs/import-clean-uids and
      export-clean-sigs/export-clean-uids options for --import-options
      and --export-options.  These are currently off by default, and
      replace the import-unusable-sigs/export-unusable-sigs options
      from version 1.4.1.

    * New export option export-reset-subkey-passwd.

    * New option --limit-card-insert-tries.

Future Directions

GnuPG 1.4.x is the current stable branch and will be kept as the easy
to use and build single-executable versions.  We plan to backport new
features from the development series to 1.4.

GnuPG 1.9.x is the new development series of GnuPG.  This version
merged the code from the Aegypten project and thus it includes the
gpg-agent, a smartcard daemon and gpg's S/MIME cousin gpgsm.  The
design is different to the previous versions and we may not support
all ancient systems - thus POSIX compatibility will be an absolute
requirement for supported platforms.  1.9 is as of now based on an
somewhat older 1.3 code but will peacefully coexist with other GnuPG


Developing and maintaining GnuPG and related software is nothing one
can do in the evening or on weekends.  We all spend a lot of time and
money on it.  David is actually doing this in his spare time beside
his day job; g10 Code employs Timo and Werner to work on this software
and would appreciate to refinance it by entering into support
contracts or other contributions.


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, Timo and Werner)

p.s.  A few hours too late we found a bug in the cURL based helper
programs which makes cURL based LDAP support unusable.  Given that
--with-libcurl is not the default we did not offtake the release but
ask you to apply the patch below.
