Changes between versions 0.4b33 and 0.4b34 (released ?????????????????)
=======================================================================

1.	Fixed the INSTALL file to reflect the actual install paths.
	Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
	reporting the bug.

2.	Fixed the configure script to only check for headers presence
	instead of trying to compile them. This should fix issues
	with old build environments. Thanks to Kari Lempiainen 
	<kari@funky.pp.fi> for reporting the bug.

3.	Fixed restore to correctly ignore sockets when comparing
	a dump (as socket cannot be properly restored anyway). Thanks
	to Gunther Reiszig <gunther@mit.edu> for reporting the bug.

4.	Fixed restore to correctly access the archive file (-A argument)
	even when using a remote tape. Thanks to Fabrice Bellet 
	<fabrice@bellet.info> for reporting the bug.

5.	Fixed (again) handling of long (largefile) seeks in rmt.
	Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
	the bug.

6.	Fixed restore corner case when dealing with large block sizes
	dump is able to write now (-b 1024). Thanks to Fabrice Bellet
	<fabrice@bellet.info> for reporting the bug.

7.	Fixed a bug preventing dump to access a filesystem having 
	a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
	for reporting the bug.

8.	Made dump store dump dates using explicit timezones, fixing a
	problem with incremental dumps if the timezone is modified 
	between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
	the bug report and the patch.

9.	Fixed a bug encountered when dumping individual files (not full
	filesystems or directories) and dangling symbolic links happen
	to be in the list of files. For as far as dump is concerned,
	dangling symbolic links are allowed, and are dumped as is.
	Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
	bug and providing the fix.

10.	Fixed open and creation modes and permissions for QFA and
	table-of-contents files in dump and restore. Thanks to 
	Philippe Troin <phil@fifi.org> for the patch.

11.	Fixed the archive file descriptor handling enabling it to be 0.
	This can happen in some cases when shell redirections are used.
	Thanks to Philippe Troin <phil@fifi.org> for the patch.

12.	Delayed the opening of archive file until after suid had been
	dropped (fixing a possible security issue if dump is suid). 
	Thanks to Philippe Troin <phil@fifi.org> for the patch.

13.	Fixed the 'S' command handling in the rmt client part.
	Thanks to Philippe Troin <phil@fifi.org> for the patch.
	
14.	Modified the end-of-tape script handling to print out statistics
	(and stop the timer) before launching the eot script. Also, the eot
	script does not get run anymore when using -M (which makes sense) or
	when multiple tapes are listed on the command line 
	(-f tape0,tape1,tapen) (which also makes sense).
	Thanks to Philippe Troin <phil@fifi.org> for the patch.

Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
=======================================================================

1.	Added a note in the restore man page clarifying the question
	'set the permissions on the current directory ?' asked by
	restore at the end of treatment in -i and -x modes.

2.	Fixed the endianess issues when reading compressed tapes.
	Thanks to Dark Force <daq4th@users.sourceforge.net> for
	reporting this bug and providing test cases.

3.	Fixed the "ACL won't be dumped" warning message (which showed
	an extra, unrelated error message). Thanks to Dragan Krnic
	<dkrnic@lycos.com> for reporting this bug.

4.	Made dump look first into /etc/mtab, then into /etc/fstab 
	when searching for filesystem paths. Also fixed some problems
	caused by binding mounts or multiple block device mounts.
	Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
	<ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
	Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
	and #160305, Sourceforge bugs #618699 and #679832).

5.	Made dump's -I option accept the value '0' meaning all the
	read errors will be ignored. This can be useful when running
	dump from unattended sessions (like cron jobs). Thanks to
	John I Wang <jiwang@users.sourceforge.net> for the suggestion.

6.	Fixed the output of dump to indicate 'blocks' instead of
	'tape blocks' in the various messages (blocks are always
	1 Kilobyte, tape blocks are 1 BK * '-b' argument), and 
	made it clearly print the current blocksize at the start of
	a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
	the suggestions.

7.	Made rmt understand long (largefiles) seeks.

8.	Fixed build with very old versions of libext2fs, where
	EXT2_FT_* constants were undefined.

9.	Made dump accept the dumpdates path on the command line
	(-D file option) instead of using only the hardcoded one.
	Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
	suggestion.

10.	Enabled rmt, LFS, readline, QFA options by default in
	./configure. Updated the configure process (new versions
	of config.guess, config.sub etc).

Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
=======================================================================

1.	Changed dump to use fcntl(F_SETLK) style locking instead
	of flock() when locking the dumpdates file. With the old 
	locking scheme, a local user having read rights on the 
	dumpdates file could be able to do a Denial of Service attack
	on dump. In order to lock the dumpdates file with the new
	scheme, the user would need to have write access on the file.
	Thanks to Richard Johnson <Richard.Johnson3@ey.com> for 
	reporting the bug (originally a bugtraq post).

2.	Fixed interactive 'ls' which caused spurious errors warnings
	about 'undefined filetypes' detected. Thanks to Jorgen Ostling 
	<jorgen_ostling@users.sourceforge.net> for reporting this 
	bug.

3.	Fixed dump's estimate when dealing with sparse inodes.

4.	Modified dump to allow setting a blocksize bigger than 32kB
	(raised the limit to 1024kB), because newer hardware needs
	this for proper operation. Thanks to Dirk Traenapp
	<dtraenapp@users.sourceforge.net> for reporting this.

5.	Fixed a bug causing Dump to stop and report an error if an
	inode number in the exclude file was followed by some amount
	of whitespace. Thanks to Jeffrey Sofferin 
	<sofferin@users.sourceforge.net> for reporting this bug.

6.	Fixed a bug which caused restore, in some particular cases,
	to ask some 'scary' questions and leave a bunch of RSTTMP
	directories behind when restoring incremental tapes. Thanks
	to Philippe Troin <phil@fifi.org> for reporting this bug and
	providing the test cases.

7.	Changed the wording when inodes are excluded from dump:
	replaced 'Added inode 7 to exclude list' with
	'Excluding inode 7 (resize inode) from dump', as suggested
	by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.

Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
===================================================================

1.	Fixed rmt open flags transmission (GNU's symbolic syntax over
	rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
	<eros@lamel.bo.cnr.it> for reporting the bug.

Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
===================================================================

1.	Made dump print out the ext2 logical block number in case of a read
	error, which can be given as an argument to debugfs' ncheck command,
	in order to find out the affected inode. Added note about this 
	usage in dump's man page.

2.	Fixed a problem in restore when reading tapes written on big
	endian machines with very old versions of dump. The patch was
	contributed by George Helffrich <george@geology.bristol.ac.uk>.

3.	Fixed the tape length calculation when using large tapes
	and compression. Thanks to Georg Lippold 
	<g_lippold@sourceforge.net> for reporting the bug.

4.	Added a new set of examples in dump_on_cd_2 directory, based
	on dump_on_cd examples but somewhat enhanced, supporting DVD
	media, and localized in english and german. Thanks to
	Georg Lippold <g_lippold@sourceforge.net> for the new scripts.

5.	Made dump save 32 bit UID/GID. Internally, this was achieved
	by switching from the old BSD inode format to the new BSD 
	inode format, which means that the tape format was changed.
	However, since all restore versions out there should 
	transparently support both inode formats, the change should
	have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
	reporting the bug.

6.	Fixed a lot of warnings in the code shown when compiling
	with 'gcc -W'. Thanks to Matthias Andree 
	<matthias.andree@stud.uni-dortmund.de> for reporting this.

7.	Fixed a small markup bug in the dump man page. Thanks to
	Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
	patch.

8.	Rewrote entirely the man pages using the tmac.an macro
	package (Linux man page format) instead of the original BSD
	format. They should be now cleaner and easier to modify.

Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
==================================================================

1.	Fixed a problem in the rmt ioctl command, where ioctl's issued from
	non Linux clients were misinterpreted. The description of the problem
	(incompatible numbering in Linux mtio opcodes) is documented at
	ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
