### GMime 3.2.7

* Added some configure logic to auto-detect the system shift-jis charset alias. (issue #81)

* Fixed tests/Makefile.am to exit with a non-negative value (issue #82)

* Fixed logic to skip expired or revoked gpg subkeys when looking for the correct subkey to
  use for signing or encrypting. (issue #88)

* Fixed a regression introduced into 3.2.6 as part of the header parsder rewrite that lost
  the ability to warn about invalid headers for non-toplevel MIME parts. (issue #89)

* Fixed S/MIME to always set GPGME_KEYLIST_MODE_VALIDATE when looking up certificates
  as this is needed in order to correctly populate the GMimeCertificates (issue #90)
