Version 3.30.4
~~~~~~~~~~~~~~
Released: 2018-10-24

This is a stable release with the following changes:
 * Add a separate "Download" step for packagekit offline updates, so that
   "Restart & Update" is instant
 * Fix a version comparison issue that led to package updates sometimes showing
   as downgrades in the OS Updates section (this needs latest appstream-glib)
 * Show the refresh button when the updates page is in the failed state
 * Notify about offline updates only after they are fully downloaded

This release also updates translations.
