 - 6th Oct 2008 libburn-0.5.4 adjusts the changes of 0.5.2 to the needs of
   Linux kernel 2.4 and introduces human readable SCSI error messages.
 
-- 6th Oct 2008 libisofs-0.6.10 fixes two bugs which prevented adding and
-  manipulation of ISOLINUX boot images.
-
-- 15th Oct 2008 libisoburn/xorriso-0.2.8 can activate and maintain an
-  ISOLINUX boot image by an EL Torito boot record.
-
-- 12th Nov 2008 libburn-0.5.6 fixes usage of freed memory by the fifo thread
-  of an aborted burn run.
-
-- 26th Nov 2008 libisofs-0.6.12 can produce a ISOLINUX isohybrid MBR on the fly
-  and allows to produce ISO images which resemble old mkisofs images.
-
-- 2nd Dec 2008 libisoburn-0.3.0. xorriso now is ready for exotic character
-  sets, for legacy FreeBSD systems which expect an outdated Rock Ridge
-  signature, and for producing ISO images with MBR which boot from hard disk
-  or USB stick. Three minor bugs were fixed.
-
-- 7th Dec 2008 libburn-0.5.8 prevents a SIGSEGV with wierd CD table-of-content
-  and improves BD-RE formatting.
