+Version: 2.3.22
+Patch Version: 00
+Script Date:  2017-06-24
+-----------------------------------
+Changes:
+-----------------------------------
+New version, tarball. Bug fix for GLX/OpenGL output. There was an unhandled case with 
+core profile data being null, which in turn triggered a bash oddity, where if the IFS is 
+\n for an array, and if the value of one element is '', then bash ignores that and does 
+not simply set an empty array key as you'd expect. The correction was to change the IFS 
+to ^, which worked fine for empty array values.
+
+However, since this bug will impact anyone with empty opengl core profile data, I recommend 
+updating inxi.
+
+Also, added support for two smaller wm, Sawfish and Afterstep.
+
+This is a good source for lists of wm:  http://www.xwinman.org/ http://www.xwinman.org/others.php 
+
+However, that does not show how to ID it, so i have to do it on a case by case, but I'll
+add an issue for showing how to get your wm of choice if it's missing to inxi.
