A new version of the Python module which wraps GnuPG has been released.=C2=
=A0
What Changed?=C2=A0=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=C2=A0This is an =
enhancement and bug-fix release, and all users are encouraged to upgrade.=
=C2=A0See the project website [1] for more information.=C2=A0
Brief summary:=C2=A0
* Subkey information is now collected and returned in a subkey_info=C2=A0 d=
ictionary keyed by the subkey's ID.
* GPG2 version is now correctly detected on OS X.
* Added expect_passphrase keyword argument for use on GnuPG >=3D 2.1 when=
=C2=A0 passing passphrase to gpg via pinentry.
* Provided a trust_keys method to allow setting the trust level=C2=A0 for k=
eys. Thanks to William Foster for a suggested implementation.
* Made the exception message when the gpg executable is not found contain t=
he=C2=A0 path of the executable that was tried. Thanks to Kostis Anagnostop=
oulos for=C2=A0 the suggestion.
* Made the error message less categorical in the case of a failure with an=
=C2=A0 unspecified reason, adding some information from gpg error codes whe=
n=C2=A0 available.

=A0The gnupg module allows Python programs to make use of the=C2=A0function=
ality provided by the Gnu Privacy Guard (abbreviated GPG or=C2=A0GnuPG). Us=
ing this module, Python programs can encrypt and decrypt=C2=A0data, digital=
ly sign documents and verify digital signatures, manage=C2=A0(generate, lis=
t and delete) encryption keys, using proven Public Key=C2=A0Infrastructure =
(PKI) encryption technology based on OpenPGP.=C2=A0
This module is expected to be used with Python versions >=3D 2.4, as it=C2=
=A0makes use of the subprocess module which appeared in that version of=C2=
=A0Python. This module is a newer version derived from earlier work by=C2=
=A0Andrew Kuchling, Richard Jones and Steve Traugott.=C2=A0
A test suite using unittest is included with the source distribution.=C2=A0
