- Update to 0.9.5:
* Key binds for release events.
* The Setting 'smart_frame_surroundings' has been changed to accept the
following new values: 'off', 'hide_all', and 'hide_gaps'. Setting it to
'hide_gaps' will only hide frame gaps when applicable, 'hide_all' and 'off'
mirror the old behaviour with regards to 'true' and 'false'.
* New format '%{ }' for easier attribute access in the sprintf command
* New setting 'show_frame_decorations' that controls when frame decorations
are shown. This should be used instead of the old 'always_show_frame'
* New frame attribute 'content_geometry'
* New tag attribute 'at_end'
* New monitor attribute 'content_geometry'
* Fix bug in ipc protocol for big-endian systems
