Hello!
We are pleased to announce the availability of a new stable GnuPG
release: version 2.4.7. This version fixes a couple of bugs.
What is GnuPG
=============
The GNU Privacy Guard (GnuPG, GPG) is a complete and free implementation
of the OpenPGP (aka LibrePGP) and S/MIME standards.
GnuPG allows to encrypt and sign data and communication, features a
versatile key management system as well as access modules for public key
directories. GnuPG itself is a command line tool with features for easy
integration with other applications. The separate library GPGME provides
a uniform API to use the GnuPG engine by software written in common
programming languages. A wealth of frontend applications and libraries
making use of GnuPG are available. As an universal crypto engine GnuPG
provides support for S/MIME and Secure Shell in addition to OpenPGP.
GnuPG is Free Software (meaning that it respects your freedom). It can
be freely used, modified and distributed under the terms of the GNU
General Public License.
Noteworthy changes in version 2.4.7
===================================
* gpg: Allow the use of an ADSK subkey as ADSK subkey. [T6882]

keys. [T7351]

key signatures. [T7426]
* gpgsm: Improvement for some rare P12 files. [rG5f9975abf5]
* scd: More mitigations against lock ups with multiple cards or
apps. [T7323, T7402]

Getting the Software
====================
Please follow the instructions found at <https://gnupg.org/download/> or
read on:
GnuPG may be downloaded from one of the GnuPG mirror sites or direct
from its primary FTP server. The list of mirrors can be found at
<https://gnupg.org/download/mirrors.html>. Note that GnuPG is not
available at ftp.gnu.org.
The GnuPG source code and its OpenPGP signature are available here:
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.4.7.tar.bz2 (8M)
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.4.7.tar.bz2.sig
A source code version with all GnuPG related libraries:
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-w32-2.4.7_20241125.tar.xz (16M)
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-w32-2.4.7_20241125.tar.xz.sig
A new release of the Windows version Gpg4win in the form of the full
featured Gpg4win installer including this version of GnuPG as well as a
full featured GUI and a PDF editor can be retrieved from here:
https://files.gpg4win.org/gpg4win-4.4.0.exe (34M)
https://files.gpg4win.org/gpg4win-4.4.0.exe.sig
and its source code is
https://files.gpg4win.org/gpg4win-4.4.0.tar.xz (251M)
https://files.gpg4win.org/gpg4win-4.4.0.tar.xz.sig
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 version of GnuPG installed, you can simply
verify the supplied signature. For example to verify the signature
of the file gnupg-2.4.7.tar.bz2 you would use this command:
gpg --verify gnupg-2.4.7.tar.bz2.sig gnupg-2.4.7.tar.bz2
This checks whether the signature file matches the source file.
You should see a message indicating that the signature is good and
made by one or more of the release signing keys. Make sure that
this is a valid key, either by matching the shown fingerprint
against a trustworthy list of valid release signing keys or by
checking that the key has been signed by trustworthy other keys.
See the end of this mail for information on the signing keys.
* If you are not able to use an existing version of GnuPG, you have
to verify the SHA-1 checksum. On Unix systems the command to do
this is either "sha1sum" or "shasum". Assuming you downloaded the
file gnupg-2.4.7.tar.bz2, you run the command like this:
sha1sum gnupg-2.4.7.tar.bz2
and check that the output matches the next line:

Internationalization
====================
This version of GnuPG has support for 26 languages with Chinese
(traditional and simplified), Czech, French, German, Italian, Japanese,
Norwegian, Polish, Portuguese, Russian, Turkish, and Ukrainian being
almost completely translated.
Documentation and Support
=========================
The file gnupg.info has the complete reference manual of the system.
Separate man pages are included as well but they miss some of the
details available only in the manual. The manual is also available
online at
https://gnupg.org/documentation/manuals/gnupg/
or can be downloaded as PDF at
https://gnupg.org/documentation/manuals/gnupg.pdf
You may also want to search the GnuPG mailing list archives or ask on
the gnupg-users mailing list for advise on how to solve problems. Most
of the new features are around for several years and thus enough public
experience is available. https://wiki.gnupg.org has user contributed
information around GnuPG and relate software.
In case of build problems specific to this release please first check
https://dev.gnupg.org/T7353 for updated information.
Please consult the archive of the gnupg-users mailing list before
reporting a bug: https://gnupg.org/documentation/mailing-lists.html.
We suggest to send bug reports for a new release to this list in favor
of filing a bug at https://bugs.gnupg.org. If you need commercial
support go to https://gnupg.com or https://gnupg.org/service.html.
If you are a developer and you need a certain feature for your project,
please do not hesitate to bring it to the gnupg-devel mailing list for
discussion.
Thanks
======
Since 2001 maintenance and development of GnuPG is done by g10 Code GmbH
and has mostly been financed by donations. Several full-time employed
developers and contractors are working exclusively on GnuPG and closely
related software like Libgcrypt, GPGME, Kleopatra and Gpg4win.
Fortunately, and this is still not common with free software, we have
established a way of financing the development while keeping all our
software free and freely available for everyone. Our model is similar
to the way RedHat manages RHEL and Fedora: Except for the actual binary
of the MSI installer for Windows and client specific configuration
files, all the software is available under the GNU GPL and other Open
Source licenses. Thus customers may even build and distribute their own
version of the software as long as they do not use our trademarks
GnuPG Desktop® or GnuPG VS-Desktop®.
We like to thank all the nice people who are helping the GnuPG project,
be it testing, coding, translating, suggesting, auditing, administering
the servers, spreading the word, answering questions on the mailing
lists, or helped us in the past with their donations.
*Thank you all*
Your GnuPG hackers
