 5. KNOWN PROBLEMS, FUTURE DEVELOPMENTS
 5.1 MULTISESSION SUPPORT
-I have now (July 1995) started support of multisession CDs. Unfortunately I
-do only have one multisession CD and no appropriate applications, so I can
-program, but testing is a little too less :-(. If you'd like to help me, 
-please contact me. As of version 1.4 you can enable the multisession support 
-in aztcd.h by setting AZT_MULTISESSION to 1. 
+Multisession support for CD's still is a myth. I implemented and tested a basic
+support for multisession and XA CDs, but I still have not enough CDs and appli-
+cations to test it rigourously. So if you'd like to help me, please contact me
+(Email address see below). As of version 1.4 and newer you can enable the 
+multisession support in aztcd.h by setting AZT_MULTISESSION to 1. Doing so 
+will cause the ISO9660-filesystem to deal with multisession CDs, ie. redirect 
+requests to the Table of Contents (TOC) information from the last session, 
+which contains the info of all previous sessions etc.. If you do set 
+AZT_MULTISESSION to 0, you can use multisession CDs anyway. In that case the 
+drive's firmware will do automatic redirection. For the ISO9660-filesystem any 
+multisession CD  will then look like a 'normal' single session CD. But never-
+theless the data of all sessions is viewable and accessible. So with practical-
+ly all real world applications you won't notice the difference. But as future
+applications may make use of advanced multisession features, I've started to
+implement the interface for the ISO9660 multisession interface via ioctl
+CDROMMULTISESSION.
 
 5.2 STATUS RECOGNITION
 The drive status recognition does not work correctly in all cases. Changing
