   It can retrieve media product info and can process track input which was
   prepared for CD-ROM XA Mode 2 Form 1. cdrskin now performs option -minfo.
 
+- 28 Oct 2009 libisoburn-0.4.4 fixes a bug with cdrecord emulation and
+  introduces new information options about media type and ISO image id strings.
+  On Linux it helps with mounting two sessions of the same media
