X-Git-Tag: v0.0.4~2
X-Git-Url: https://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=a883b9664639b2e80dba9b4e616afba8f3d2163b;p=xfce4-hdaps.git

Fixed a status update bug thanks to Evgeni Golov.
Added a new state constant, HDAPS_ON.
Changed hdaps_update_status to use the new constant when determining whether or not HDAPS has changed states from "on" to "off."
