Version 0.7.3
~~~~~~~~~~~~~~
Released: 2014-10-10

Features:
 * Implement basic support for the new icon cache layout (Matthias Klumpp)

Specification:
 * spec: Update the icon-cache layout to allow icons with larger sizes (Matthias Klumpp)

Bugfixes:

Version 0.7.2
~~~~~~~~~~~~~~
Released: 2014-09-22

Notes:
 * This release drops the PackageKit plugin (and the build dependency on PK alltogether).
   This means that AppStream will no longer automagically update the Xapian index. Please
   make sure that tools or packages which modify the AppStream distro XML/YAML call
   'appstream-index refresh' when they are done. (reason for dropping the plugin is PackageKit
   removing support for plugins with its 1.0 release)

Bugfixes:
 * Ensure that we do not convert NULL to a C++ string (Matthias Klumpp)
