Changelogs from :/debian/changelog:

    fluxgui (1.1.10) wily; urgency=low

      * fix xflux-gui#51: some of
          the the color temps I added in 1.1.9 were not actually supported
          :P
            * fix gtk-icon-theme related warnings. These were innocuous,
          but
              mentioned in most bug reports.
                * fix xflux-gui#35:
          screen color
              was not reset to normal when closing fluxgui.
                * fix xflux-gui#38:
          remove confusing
              GUI element.
                * fix xflux-gui#16:
          previewing the
              already chosen color during the daytime didn't work.
