  warnings for old Algorithms (bsc#1093151)

  encrypted emails (bsc#1093152)

  This update also includes new and updated functionality:

  - The Encryption and Signing buttons now work for both OpenPGP and S/MIME.
  Enigmail will chose between S/MIME or OpenPGP depending on whether the
  keys for all recipients are available for the respective standard

  - Support for the Autocrypt standard, which is now enabled by default

  - Support for Pretty Easy Privacy

  - Support for Web Key Directory (WKD)

  - The message subject can now be encrypted and replaced with a dummy
  subject, following the Memory Hole standard forprotected Email Headers

  - keys on keyring are automatically refreshed from keyservers at irregular
  intervals

  - Subsequent updates of Enigmail no longer require a restart of Thunderbird

  - Keys are internally addressed using the fingerprint instead of the key ID
