Update to 2.0.7. This is maintenance release with a few minor enhancements.
Changes:
 * Fixed encryption problem if duplicate certificates are in the
   keybox.
 * Add new options min-passphrase-nonalpha, check-passphrase-pattern,
   enforce-passphrase-constraints and max-passphrase-days to
   gpg-agent.
 * Add command --check-components to gpgconf.  Gpgconf now uses the
   installed versions of the programs and does not anymore search via
   PATH for them.
