"This update for claws-mail fixes the following issues :

  - Additional cleanup of the template handling

claws-mail was updated to 3.17.8 (boo#1177967)

  - Shielded template's |program() and |attach_program() so
    that the command-line that is executed does not allow
    sequencing such as with && || ;, preventing possible
    execution of nasty, or at least unexpected, commands

  - bug fixes: claws#4376

  - updated English, French, and Spanish manuals

  - Update to 3.17.7 

  - Image Viewer: Image attachments, when displayed, are now
    resized to fit the available width rather than the
    available height.

  - -d is now an alias to --debug.

  - Libravatar plugin: New styles supported: Robohash and
    Pagan.

  - SpamAssassin plugin: The 'Maximum size' option now
    matches SpamAssassin's maximum; it can now handle
    messages up to 256MB.

  - LiteHTML viewer plugin: The UI is now translatable. Bug
    fixes :

  - bug 4313, 'Recursion stack overflow with rebuilding
    folder tree'
