-	sun compilation with OSS and sun sound drivers fixed

-	multiple filenames/paths for multiple tracks

-	support OSS sound library under NetBSD (untested)

-	now prints percentage per track (for xcdroast)


Readcd:

-	New. This is currently a stripped down version of scgskeleton.
	Unlike its brother, it compiles on all OS.
	readcd allows you to read data CD's. Because it ignores the
	CD disk label, it may be used to copy Solaris boot CD's.

	Call:

		readcd dev=b,t,l f=filename

	Select function 11 to copy a CD to a file. If you are trying
	to copy a CD-R that has been made in TAO mode, modify the
	value for Number of sectors to copy by subtracting '2' from the
	displayed default value.	

-	First version of enhancements that Thomas Niederreiter likes for
	XCD-roast

-	Verbose output now goes to stderr to allow readcd | cdrecord

-	README.copy now mentiones readcd instead of scgskeleton

-	Now write to SCSI is possible in non interactive mode too.

-	It should now be safe to install readcd suid root.
	This allows xcdroast to work for non root users.
	-	readcd will not write in suid mode
	-	readcd will only read from CD-ROM drives in suid mode
		NOTE that this causes xcdroast to fail reading
		from the Yamaha CDR-100 for a non root user.


Mkisofs:

-	Now officially maintained by me (J鰎g Schilling [e-mail])
	Eric Youngdale has not enough time do it anymore.
	James Pearson seems to be short in time too.

	The official mkisofs-1.12 is first available inside the
	cdrtools package.

	There will probably be a separate mkisofs packet inside a
	schily makefile system (including enhanced error reports and
	SCSI support) but I believe that it is the best way to keep
	the newest release inside the cdrtools package. This has been
	prooved a good way for cdda2wav and as most people need
	all tools from the cdrtools package it saves space. Note
	that GNU configure and the schily makefile system create
	approx. a one megabyte package overhead.

	What I planned for the near future is mainly changing mkisofs
	in a way that makes it easier to maintain. Mkisofs currently
	suffers from complex #ifdef's. My main goal is to use more of the 
	portability support include files from my makefilesystem
	to minimize portability efforts.

-	Now tested on Win NT-4.0 with Cygwin32-beta20

-	fixed a bug in the IS_???? macro defines for stat.h
	that prevented correct compilation on CYGWIN32

-	changed some open()/fopen() calls to use binary DOS mode
	to allow mkisofs to work correctly on CYGWIN32

-	man page updated

-	-volset-size -volset-seqno options added to allow multi-volume
	archives (e.g. OS installation CD sets). NOTE: -volset-size must
	be specified before -volset-seqno on each command line.

-	README.session updated

-	new options -hide & -hide_joliet from James Pearson

-	allow the full printable ISO-8859-1 set to be converted into UNICODE
	for Joliet disks.

-	Allow Volume sets ala ISO-9660

-	New options -abstract -biblio -copyright -sysid
	-volset -volset-size -volset-seqno

-	-volset-size -volset-seqno options added to allow multi-volume
	archives (e.g. OS installation CD sets). NOTE: -volset-size must
	be specified before -volset-seqno on each command line.

-	mkisofs now is able to create a new session that is not
	related to a startsector '0'. This now makes it easy to
	create a CD+ where the first session contains audio and the second
	session contains a ISO-9660 filesystem.
	Use "mkisofs -C0,xxx ...."
	and ommit -Mdevice to use this new feature.

-	Check for overflow in the Joliet directory tables.

-	changed UNICODE level for Joliet
	As mkisofs just "expands" 8 bit character codes to 16 bits and does
	nothing special with the Unicode characters, therefore shouldn't mkisofs
	really be stating that it's using UCS-2 Level 1, not Level 3 for
	the Joliet directory tree.  

-	SCSI read function now checks for drive's sector size and
	recalculates the number of sectors to transfer.

-	SCSI read function now checks if the amount of sectors to be
	transferred exceed the maximum transfer size for SCSI requests
	on the actual system.

	This could happen when doing multi-session in filesystems
	that have really big directories.

-	Fixed a bug with filename handling that was only present with
	IRIX (unsigned char) and character code >= 0x80

-	make the options 'no-split-symlink-components" and 
	"no-split-symlink-fields" work

-	Re-Read TRANS.TBL correctly for multi session.

-	Joliet name <translation table> changed to TRANS.TBL

-	System id string for OS/2

-	HAVE_READLINK autoconf new

-	mkisofs should now compile on OS/2 out of the box

-	mkisofs now uses comerr() and thus prints error messages in standard
	format including a text string for 'errno'.
	This makes it much easier to understand error messages and to check
	what caused an error.

-	Fixed a bug with 64 bit support on OSF-1 Aplha

-	include statdefs.h in all sources that include sys/stat.h to
	make the S_IS*() macros work on all exotic systems.

-	fixed bug in tree.c that prevented compilation on OS/2
	because of missing major()/minor().

Last patches from Eric:
	-	Additional error checking for reading from multi session source
		disks.

	-	Round up byte count when reading merging directory from old
		disk when doing multi session.

	-	Better bound checking when reading TRANS.TBL files.

-	-version option to print current version

-	limit Joliet name comparison to 64 chars (see Joliet specs)
	(Patch from James Pearson)

-	Allow Rock Ridge version 2
	(Patch from James Pearson)

-	correctly compare times of inodes for multi session merging

-	Call to setrlimit() for NetBSD removed. It seemed to lower
	limits with current NetBSD releases.

-	Now default to correct system ID's for most operating systems.
	(at least all OS that are supported by libscg are now present as default)

-	Set the sizes for directories . & .. in the root directory of a new session
	on a multi session filesystem.

-	isoinfo.c now correctly reports ucs_level (Unicode)
	(Patch from James Pearson)

-	Allow virtual directory loops

	mkisofs ..... /usr /manuals/=/usr/man/
	is now allowed. I may be used to create CD's that sum up to more 
	than the physical medium size.

-	Abort if ISO or RR tree cannot be sorted.

-	Print a message if for some reason a directory don't have at
	least a . and .. entry.

-	Now it is safe to install mkisofs suid root.
	This is needed to allow XCD-Roast to create multi-session CD's
	without the need for xcdroast run as root.

-	New funtion open_merge() now tests if a possible argument
	to the -M option is a filename before using it as SCSI dev spec.

-	New option -sparc-boot to create bootable CD's for Sun sparc systems.

-	New option -generic-boot to add generic boot code that is located
	on sectors 0..15 on the CD.

-	The -a option is now obsolete. Now all files are put on CD by default.
	To suppress backup files use the new option -nobak

-	-nobak option new to exlude files that contain a '~' or a '#' or
	end in '.bak'

-	Support for Eltorito Hard-disk-emulation boot from H.P.Anvin
	Note that the original source was non portable and I could not
	test if my portable version work correctly.

-	Support for Eltorito No-emulation boot from H.P.Anvin
	Note that the original source was non portable and I could not
	test if my portable version work correctly.

-	Support for Eltorito boot-disable boot from H.P.Anvin

-	correctly handle boot image and boot catalog if the first
	pathspec contains graft pointer (dir=dir)

-	Eltorito boot catalog is now a 'virtual file' (thanks to James Pearson)
	No need to write to the source tree anymore.

-	man page corrected:

	-l option now lists the correct max ISO filename length of 30 chars

	-L option now notes that this option only affects the ISO9660 names

-	Now merging graft directories in multi-session should finally work
	thanks to a patch by Francis Verscheure
	Email : [e-mail] Home Page : perso.wanadoo.fr/francis.verscheure/  

	mkisofs -o S1	...	Dir/file1=somefile
	mkisofs -o S2 -M S1 ...	Dir/file2=some_other_file

	Did not work before.

-	Correctly abort if there were problems with bad Rock Ridge signatures
	while reading an old session.

-	New option -hide-joliet-trans-tbl to hide TRANS.TBL files
	from the Joliet tree.

-	New option -hide-rr-moved to change the Rock Ridge name
	of the RR_MOVED directory to .rr_moved

-	Fixed a bug with an unitialised variable in the GNU getopt() code.

-	Initialise the RR structures for the RR_MOVED directory.

-	Man page corrected: -l can only allow 30 chars in filename as a limitation
	of ISO-9660

-	Allow again to hide the boot catalog (new patch from James Pearson)

		With earlier versions of mkisofs (pre v1.12b5-js-a36), you could "hide" the 
		boot and the boot catalog file using: 
 
		mkisofs -o output.iso -r -b boot -hide boot -hide boot.catalog dir 

		Both files will be written to disk, but will not be visable to the 
		ISO9660 directory - the boot descriptor will still know at which extent the 
		boot catalog starts. (However, I haven't actually tried this ...). 

-	Fixed a seriuos bug related to the structures iso_path_table and
	iso_directory_record.

	Both structures have an odd length and some compilers (e.g. on
	Sun3/mc68020 systems) will padd these structures to an even size.
	For this reason it was a bad idea to use sizeof(iso_path_table)
	of sizeof(iso_directory_record) for on disk size computations.

	The changes affect central functionality and it is needed to do
	testing if my changes will not introduce a new bug.

-	Version information now includes CPU Vendor and OS info

-	diag/isoinfo.8 man page now contains information for "devdump" too.

-	diag/isoinfo.c has a new option -d to print a dump
	of the PVD of a ISO-9660 filesystem.
	This is currently in a very embryonic state but is intended
	for Thomas Niederreiter to see what he may display in X-CDRoast.

-	New option -U allows to totally violate ISO-9660
	This helps to create CD's for HP-UX and
	to circumvent a bug in the boot-prom code in IBM's CHRP PPC
	systems.

-	New option -gui to help xcdroast

-	Unreadable  directories are no longer transformed into
	plain files

-	-f option now finaly works as expected even for
	symlinks that would cause directory loops on the CD

	New additions from James Pearson:

	-	New Options: -hide-list -hide-joliet-list -path-list -exclude-list
	
	-	New Option: -table-name

-	Added bug list to man page

-	Joliet Unicode conversion now works correctly if the target	
		string has odd length.

-	Now using <device.h> to make the major()/minor() macros work
	again on FreeBSD

-	Now uses SCSI read-g1 command when reading an old session from a
	multisession CD in an ATAPI drive.

-	New option -no-rr to disable reading Rock Ridge signatures from
	previous sessions. This may help to avoid problems with illegal
	Rock Ridge signatures in previous session.

-	Workaround for a core dump problem with multi-session and RR_MOVED
	in pevious sessions.

	Mkisofs still does not work 100% correct with multi-session if
	the previous session uses deep directory relocation.
	I don't see that this bug can be fixed before a final 
	cdrtools-1.8/mkisofs-1.12
