Noteworthy changes in version 1.4.1
-------------------------------------------------
* [W32] The algorithm for the default home directory changed:
First we look at the environment variable GNUPGHOME, if this one
is not set, we check whether the registry entry
HKCU\Software\GNU\GnuPG:HomeDir has been set and if this fails
we use a GnuPG directory below the standard application data
directory (APPDATA) of the current user. Only in the case that
this directory cannot be determined, the old default of c:\gnupg
will be used. The option --homedir still overrides all of them.
* New --rfc2440-text option which controls how text is handled in
signatures. This is in response to some problems seen with
certain PGP/MIME mail clients and GnuPG version 1.4.0. More

option --with-libcurl. Without this option, the existing HTTP
code is used for HTTP, and HTTPS and FTP are not supported.
* When running a --card-status or --card-edit and a public key is
available, missing secret key stubs will be created on the fly.
Details of the key are listed too.
* [W32] The algorithm for the default home directory changed:
First we look at the environment variable GNUPGHOME, if this one
is not set, we check whether the registry entry
{HKCU,HKLM}\Software\GNU\GnuPG:HomeDir has been set. If this
fails we use a GnuPG directory below the standard application
data directory (APPDATA) of the current user. Only in the case
that this directory cannot be determined, the old default of
c:\gnupg will be used. The option --homedir still overrides all
of them.
* [W32] The locale selection under Windows changed. You need to
enter the locale in the registry at HKCU\Software\GNU\GnuPG:Lang.
For German you would use "de". If it is not set, GnupG falls
back to HKLM. The languages files "*.mo" are expected in a
directory named "gnupg.nls" below the installation directory;
that directory must be stored in the registry at the same key as
above with the name "Install Directory".

Internationalization support:

1. Decide where to store the translation files for your language.
Here we assume the directory "c:/gnu/locale/fr"

2. Set the directory with the translations into the Registry under
the key:
HKEY_CURRENT_USER -> Control Panel -> Mingw32 -> NLS
(you probably need to create the keys Mingw32 and NLS) using a string
entry with the name "MoDir".
3. Select which language to use and copy the currect translation file
under the name "gnupg.mo" into the directory set in step 2
(Example: "copy fr.mo c:\gnu\locale\fr\gnupg.mo")
4. Done.
Store the locale id (like "de") into the registry under the key
HKEY_CURRENT_USER\Software\GNU\GnuPG with the name "Lang".
