Noteworthy changes in version 2.0.13
-------------------------------------------------

 * GPG now generates 2048 bit RSA keys by default.  The default hash
   algorithm preferences has changed to prefer SHA-256 over SHA-1.
   2048 bit DSA keys are now generated to use a 256 bit hash algorithm

 * The envvars XMODIFIERS, GTK_IM_MODULE and QT_IM_MODULE are now
   passed to the Pinentry to make SCIM work.

 * The GPGSM command --gen-key features a --batch mode and implements
   all features of gpgsm-gencert.sh in standard mode.

 * New option --re-import for GPGSM's IMPORT server command.

 * Enhanced writing of existing keys to OpenPGP v2 cards.

 * Add hack to the internal CCID driver to allow the use of some
   Omnikey based card readers with 2048 bit keys.

 * GPG now repeatly asks the user to insert the requested OpenPGP
   card.  This can be disabled with --limit-card-insert-tries=1.

 * Minor bug fixes.


Noteworthy changes in version 2.0.12 (2009-06-17)
-------------------------------------------------

 * GPGSM now always lists ephemeral certificates if specified by
   fingerprint or keygrip.

 * New command "KEYINFO" for GPG_AGENT.  GPGSM now also returns
   information about smartcards.

 * Allow encryption with legacy Elgamal sign+encrypt keys with option
   --rfc2440.

 * Windows is now a supported platform.

 * Made sure that under Windows the file permissions of the socket are
   taken into account.  This required a change of our socket emulation
   code and changed the IPC protocol under Windows.


Noteworthy changes in version 2.0.7 (2007-09-10)
------------------------------------------------

 * Fixed encryption problem if duplicate certificates are in the
   keybox.

 * Made it work on Windows Vista.  Note that the entire Windows port

   machine.  Bug fixes for gpg2's card key generation.


Noteworthy changes in version 2.0.4 (2007-05-09)
------------------------------------------------

 * The server mode key listing commands are now also working for
   systems without the funopen/fopencookie API.

 * PKCS#12 import now tries several encodings in case the passphrase
   was not utf-8 encoded.  New option --p12-charset for gpgsm.

 * Improved the libgcrypt logging support in all modules.


Noteworthy changes in version 2.0.3 (2007-03-08)
------------------------------------------------

 * By default, do not allow processing multiple plaintexts in a single
   stream.  Many programs that called GnuPG were assuming that GnuPG
   did not permit this, and were thus not using the plaintext boundary
   status tags that GnuPG provides.  This change makes GnuPG reject
   such messages by default which makes those programs safe again.
   --allow-multiple-messages returns to the old behavior. [CVE-2007-1263].

 * New --verify-option show-primary-uid-only. 

 * gpgconf may now reads a global configuration file to select which
   options are changeable by a frontend.  The new applygnupgdefaults
   tool may be used by an admin to set default options for all users.

 * The PIN pad of the Cherry XX44 keyboard is now supported.  The
   DINSIG and the NKS applications are now also aware of PIN pads.


Noteworthy changes in version 2.0.2 (2007-01-31)
------------------------------------------------

 * Fixed a serious and exploitable bug in processing encrypted
   packages. [CVE-2006-6235].

 * Added --passphrase-repeat to set the number of times GPG will
   prompt for a new passphrase to be repeated.  This is useful to help
   memorize a new passphrase.  The default is 1 repetition.

 * Using a PIN pad does now also work for the signing key.

 * A warning is displayed by gpg-agent if a new passphrase is too
   short.  New option --min-passphrase-len defaults to 8.

 * The status code BEGIN_SIGNING now shows the used hash algorithms.


Noteworthy changes in version 2.0.1 (2006-11-28)
------------------------------------------------

 * 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,CVE-2006-6169]

-------------------------------------------------

 * In --with-validation mode gpgsm will now also ask whether a root
   certificate should be trusted.

 * Link to Pth only if really necessary.

 * Fixed a pubring corruption bug in gpg2 occurring when importing
   signatures or keys with insane lengths.

 * Fixed v3 keyID calculation bug in gpg2.

 * More tweaks for certificates without extensions.


Noteworthy changes in version 1.9.92 (2006-10-11)
-------------------------------------------------

   The configure option --enable-gpg is still required to build this
   gpg part.  For production use of OpenPGP the gpg version 1.4.5 is
   still recommended.  Note, that gpg will be installed under the name
   gpg2 to allow coexisting with an 1.4.x gpg.

 * API change in gpg-agent's pkdecrypt command.  Thus an older gpgsm
   may not be used with the current gpg-agent.

 * The scdaemon will now call a script on reader status changes.

 * gpgsm now allows file descriptor passing for "INPUT", "OUTPUT" and
   "MESSAGE".

   commands.

 * Internal changes for OpenPGP cards. New Assuan command WRITEKEY.

 * GNU Pth is now a hard requirement.

 * [scdaemon] Support for OpenSC has been removed.  Instead a new and
   straightforward pkcs#15 modules has been written.  As of now it
   does allows only signing using TCOS cards but we are going to
   enhance it to match all the old capabilities.

 * [gpg-agent] New option --write-env-file and Assuan command
   UPDATESTARTUPTTY.

 * [gpg-agent] New option --default-cache-ttl-ssh to set the TTL for

 * Added simple tool addgnupghome to create .gnupg directories from
   /etc/skel/.gnupg.

 * Various minor bug fixes and cleanups; mainly gpgsm and gpg-agent
   related.


Noteworthy changes in version 1.9.3 (2003-12-23)
------------------------------------------------

 * New gpgsm options --{enable,disable}-ocsp to validate keys using
   OCSP. This option requires a not yet released DirMngr version.
   Default is disabled.

 * The --log-file option may now be used to print logs to a socket.

   disable OpenSC use at runtime, so that PC/SC or ct-API can still be
   used directly.

 * Rudimentary support for the SCR335 smartcard reader using an
   internal driver.  Requires current libusb from CVS.

 * Bug fixes.


Noteworthy changes in version 1.9.0 (2003-08-05)
------------------------------------------------

      ====== PLEASE SEE README-alpha =======

   temporary change to allow co-existing with stable gpg versions.

 * ~/.gnupg/gpg.conf-1.9.0 is fist tried as config file before the
   usual gpg.conf.

 * Removed the -k, -kv and -kvv commands.  -k is now an alias to
   --list-keys.  New command -K as alias for --list-secret-keys.

 * Removed --run-as-shm-coprocess feature.

 * gpg does now also use libgcrypt, libgpg-error is required.

 * New gpgsm commands --call-dirmngr and --call-protect-tool.
