Changes between versions 0.4b22 and 0.4b23 (released ????????????)
==================================================================

1.	Fixed a buffer overflow in restore/tape.c. Patch provided by
	Marcus Meissner (Caldera International Security Dept.).

2.	Implement the Sun rmt extended protocol. Patch submitted
	by Ian Gordon <iangordon@users.sourceforge.net>.

3.	Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of 
	the linux kernel header. This ensures that dump always has the
	latest version of this file. Patch submitted by
	Andreas Dilger <adilger@turbolinux.com>.

4.	Report any filesystem present in either /etc/fstab with a 
	positive passno or /etc/dumpdates in dump -w output.
	Patch submitted by Andreas Dilger <adilger@turbolinux.com>.

5.	Fixed the looping problem in dump introduced in the 
	previous version.

6.	Changed the -B option of dump to limit the size of 
	_compressed_ output per volume if compression is on.
	Patch contributed by Helmut Jarausch 
	<jarausch@igpm.rwth-aachen.de>.

7.	Fixed a bug in reading the operator typed file/tape path for
	the next volume in restore.

8.	Implemented a "-F script" option to restore which permits the
	user to specify a script which will be launched at the
	beginning of each tape, useful for automatic programming of
	tape changers for example. See the restore man page for the
	script parameters and return codes.

9.	Small fix for the QFA routines provided by Uwe Gohlke 
	<uwe@ugsoft.de>, and some recommendations for QFA uses in
	the man pages.

10.	Fixed the multivolume restoring where making a mistake
	to the 'Mount next tape' prompt caused several blocks to
	be lost.

11.	Enhanced the -e option of dump to take as a parameter a
	comma separated list of inode numbers.

12.	Added the -E option to dump which specify a file containing
	inode numbers to exclude from the dump.

Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
==================================================================

1.	Made dump report the number of blocks dumped per volume.
	Thanks to Kenneth Porter <shiva@well.com> for the suggestion.

2.	Fix a bug in dump where waiting too much at the 'change volumes'
	question caused the volume to be rewritten. Thanks to
	Graham Reed <greed@users.sourceforge.net> for reporting the
	bug and providing a patch.

3.	Added a compression option to dump, contributed by Jerry
	Peters <gapeters@worldnet.att.net>.

	WARNING: the compression works only on files/pipes and 
	drives supporting variable block size.

	WARNING2: tapes created using the compression feature are
	incompatible with the standard dump tape format, and a
	version of restore >= 0.4b22 will be needed for extraction.

4.	Fixed some compilation problems for glibc 2.2.2 and 64 bit 
	architectures. Thanks to Paul Slootman <paul@debian.org> for
	the patch and to Bdale Garbee <bdale@gag.com> for forwarding
	it upstream.

5.	Many cleanups (CPP defines, const char warnings, check of
	ext2fs COMPAT flags, time_t cleanups, added libext2 version
	in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.

6.	Made --prefix option work in configure. All the install path
	are now based on the configure parameters.

7.	Added the Quick File Access mode in dump/restore, contributed
	by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
	a file tape position for each inode, and this file is used by 
	restore (if called with parameter Q and the filename)
	to directly position the tape at the file restore is currently 
	working on.  This saves hours when restoring single files from
	large backups, saves the tapes and the drive's head. Use
	--enable-qfa option of configure to compile in the QFA support.

8.	Added the possibility to dump several files and directories
	in a single invocation of dump. Thanks to Uwe Gohlke 
	<uwe@ugsoft.de> for implementing this option.

9.	Fixed the dumping and restoring of files with holes
	(files ending with holes didn't get dumped or restored 
	correctly).

10.	Fixed a socket descriptor leak in dump, which leaved opened
	3 file descriptors per dump process (and there is one dump
	process per tape).

11.	Fixed dump large file system support, by explicit use of
	open64/lseek64/etc functions (explicit use needed because 
	e2fsprogs libraries don't behave well when compiled with 
	FILE_OFFSET_BITS=64).

Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
======================================================================

1.	Fixed some bugs in the dump -w|-W logic introduced by
	the previous version. Thanks to Andreas Dilger 
	<adilger@turbolinux.com> for his help on this one.

2.	Fixed again a compilation problem when using old e2fs
	headers (filesystem label related). Thanks to many users
	who reported this stupid error.

3.	Fixed a build problem on old lib5 based systems dealing with 
	_PATH_MNTTAB being undefined. Thanks to John Adams
	<johna@onevista.com> for reporting the bug.

4.	Improved the error detection in restore when creating
	the temporary files in TMPDIR. Now restore will corectly
	report a 'no space left on device' error instead of 
	strange errors which could imply an archive corruption.
	Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
	bgjenero <bgjenero@sympatico.ca> for reporting the bug.

5.	Added the throughput information in dump's progression
	messages.  Thanks to Andreas Dilger <adilger@turbolinux.com> 
	for the patch.

6.	Use libext2fs's inode scanning routines, which are particularly
	robust when dealing with errors (especially when having some
	bad blocks on the filesystem). Many thanks to Colin
	<colin@horizon.com> for reporting the bug, investigating
	the issues, finding a workaround, writing the patch and
	fully testing it... (of course, if this patch will break
	anything, he is to blame for :-)).

7.	Made dump and restore LFS aware. Dump can dump a filesystem
	containing large files, generate a large file on output and
	restore can restore them. This feature is not enabled by
	default, use --enable-largefile option of configure to enable
	it (you need to have a LFS aware glibc though). Thanks to
	Andrea Arcangeli <andrea@suse.de> for submitting the patch,
	and to Theodore T'so <tytso@valinux.com> for his always
	useful thoughts.

8.	Made dump ask upon a tape write error if it should rewrite
	the current volume (assume this is a bad tape) or if it should
	assume an end-of-tape condition (useful for tape drives which
	behaves badly at the end of the tape). Thanks to Andreas
	Dilger <adilger@turbolinux.com> for the suggestion.

Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
=======================================================================

1.	Fixed a small compilation problem due to a change
	in the definintion of the struct sigaction in
	glibc 2.0 / libc5. Thanks to Gunther Schlegel 
	<schlegel@riege.de> for reporting the bug and to
	Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
	a fix.

2.	Modified the label and uuid analysis in order to be 
	self-contained (independant of kernel/libc headers). This 
        should fix the compile with older kernel/libc headers and
	will preserve the functionality. Thanks to Bernhard Erdmann
	<bernhard.erdmann@gmx.de> for reporting the bug.

3.	The 'exclude inode' option, if applied to a directory
	inode, excludes now correctly all the leaves of this 
	directory. Thanks to John R. Dennison 
	<gerdesas@users.sourceforge.net> for reporting the bug.

4.	Fixed the '-e' option to disable the possibility
	to exclude the root inode (which causes the dumps to
	be unreadable by restore). Prevented array overflow
	when multiple -e options are used.

5.	Fixed dump to correctly interpret a filesystem argument
	which is a mountpoint and it is not an absolute path 
	(as specified in the fstab). Thanks to Bernhard R. Erdmann 
	<be@berdmann.de> for reporting the bug.

6.	Made dump able to backup files larger than 2 GB. Note that
	dump still doesn't cope with files larger than 4 GB.

7.	Restore the real uid and gid before invoking an external
	RSH program (big hole when dump or restore is suid root!).

8.	Get the values for the default tape device and the location
	of fstab file from the system headers. Thanks to
	Andreas Dilger <adilger@turbolinux.com> for the patch.

9.	Made dump -w|-W report all recognized filesystems 
	present in either /etc/fstab or /etc/dumpdates, and present
	the list in the same order as in fstab file. Thanks
	to Andreas Dilger <adilger@turbolinux.com> for the patch.

10.	Made dump's -a (automatic end of tape detection) the
	default. Specifying one of -B, -c, -d or -s options will
	override the EOM detection. Thanks to Andreas Dilger
	<adilger@turbolinux.com> for the patch.

11.	Save the ext2 filesystem label into the dump volume label.
	Specifying a volume label on the command line (-L option)
	will override this feature. Thanks to Andreas Dilger
	<adilger@turbolinux.com> for the patch.

Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
=====================================================================

1.	Fixed the signal handling in dump (which I broke in 0.4b17)
	which was causing several strange dump failures (dump
	hanged or segmentation faults etc). 

2.	Specified the default blocksize in the dump man page.

3.	Changed two info messages of restore to be written on stdout
	instead of stderr in order to leave stderr only for errors
	or warnings. Thanks to Stephen Atwell 
	<satwell@urbana.css.mot.com> for the suggestion.

4.	Corrected an off by one calculation which prevented
	dumping a directory having a 1 character name length.
	Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
	for reporting the bug.

5.	Reinforce dump in order to allow only level 0 and no
	-u option when dumping a subdirectory, and document 
	this in the man page. Thanks to Bernhard Erdmann 
	<bernhard.erdmann@gmx.de> for reporting the bug.

6.	Fixed a small harmless bug in restore which caused
	in some conditions hard links to be restored several
	times (therefore generation some warning messages).
	Thanks to Kenneth Porter <shiva@well.com> for
	reporting the bug.

7.	Updated the RPM spec file to the latest RedHat version,
	providing FHS packaging and other cosmetic changes.
	You will need RPM version >= 3.0.5 in order to build the RPM.

8.	Updated the configure script to check for libtermcap
	before checking for libreadline, because we need this
	library in order to compile the readline support.

9.	Made dump understand the LABEL= and UUID= notation
	both in /etc/fstab and on the command line. Note that
	you will need the /proc filesystem in order to use
	these notations. Thanks to Erik Troan <ewt@redhat.com> 
	for providing the patch.

Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
===================================================================

1.	Fixed a potential buffer overflow in restore. Thanks
	to Stan Bubrouski <satan@fastdial.net> for reporting 
	the bug.

2.	Fixed a readline-related bug which prevented
	'cat DUMPFILE | restore -i -f -' from working. Thanks
	to Charles Karney <karney@users.sourceforge.net>
	for the bug report.

3.	Changed a few "panic" into "exit", causing restore to
	be more stable against some attacks (like the last one
	reported on Bugtraq, although the last version of restore
	was not vulnerable - just dumped core). Thanks to
	Andreas Hasenack <andreas@conectiva.com.br> for reporting
	the bugs to me.

4.	Removed the suid-root bit on dump and restore in the
	default build (and generated RPMs). It should be safer
	now. Users who need the suid-root capabilities in order
	to make network backups should read first the man page
	of dump and enable the suid bit manually.

5.	Added -ltermcap to the compile parameters for restore
	when using readline support, in order to make the compile
	process work on some systems (SuSE ?). Thanks to 
	Patrik Schindler <poc@pocnet.net> for reporting the bug.

Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
====================================================================

1.	The -F script is called now *only* at the end of a tape,
	not at the end of the dump. Thanks to Christian Haul
	<haul@informatik.tu-darmstadt.de> for the bug report.

	Normally, the device name and the current volume number
	are passed on the command line of the script. However,
	if you want the old style script (with no arguments
	passed on the command line), you can enable it in
	configure with the --enable-oldstylefscript.

2.	Use posix signal handling to preserve dump functionality 
	with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
	the patch.

3.	Made the exit code of restore in case of a 'C'ompare
	command reflect the result of the compare. An exit status
	of 0 means the dump archive is correct, 1 means tape errors,
	2 means that some files were modified. Thanks to Kenneth Porter
	<shiva@well.com> for the suggestion.

4.	Made (finally) quotes work in interactive restore.

5.	Small fixes in order to allow dump to compile with a 
	really old e2fsprogs version. Thanks to Ian Zimmerman 
	<itz@speakeasy.org> for the bug report.

6.	Add GNU readline capabilities to interactive restore.
	Use configure's --enable-readline flag to enable this feature.
	Thanks to Patrik Schindler <poc@pocnet.net> for the
	suggestion.

7.	Do the compare on the fly in restore 'C' mode (this will
	allow not to exhaust the available /tmp space when 
	ccmparing large files). Thanks to Kenneth Porter
	<shiva@well.com> for the suggestion.

Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
====================================================================

1.	Fixed some several duplicate 'DUMP: DUMP:' in the
	output of dump.

2.	Corrected the estimation of blocks to dump. Note that
	this is still wrong for large directory inodes, due
	to the size of a BSD directory entry on the tape
	(estimation is based on the size of the ext2 directory,
	which is smaller because it doesn't contain the null
	character at the end).

3.	Made dump report the total number of MB written to
	tape at the end of run. Thanks to W. Reilly Cooley
	<wcooley@nakedape.cc> for the patch.

4.	Added the -X option to restore giving the possibility
	to read the names of the files to be extracted/listed 
	from a text file (in addition of the command line). 
	Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the 
	patch.

5.	Added the device name and the current volume number
	as arguments to the end of tape script (dump -F option).

6.	Made the multi-volume dump work again (after having 
	broken it in 0.4b15). 

Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
===================================================================

1.	Added a prompt command in interactive restore mode. Thanks
	to Andreas Dilger <adilger@home.com> for the patch.

2.	Fixed a buffer overflow problem in dump (caused by 
	not checking the size of the filesystem parameter). 
	Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
	reporting this on Bugtraq (and to several dump users
	who forwarded me his mail).

3.	Added the '-F script' option to dump in order to 
	launch a script at the end of each tape (to be used
	with a tape changer, or to notify the sysadmin by
	pager etc.).

4.	Fixed a bug in restore compare code caused by the changes 
	I made in 0.4b14.

5.	Fixed the treatment of options using the old BSD syntax
	in both dump and restore.

Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
=======================================================================

1.	Fixed a bug in dump which may have caused invalid deleted 
	directories to be dumped out if they were deleted after the
	mapping pass. This could occure on active filesystem and lead
	to heap corruption (causing dump malfunction in many possible ways).
	Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
	bug and submitting the patch.

2.	Fixed the handling of the filesystem parameter in dump. A
	'/mnt/disk' parameter caused the disk contents to be dumped,
	but a '/mnt/disk/' parameter caused the mountpoint directory
	to be dumped (generally an empty directory).

3.	Improved the output of dump in order to tell which directory
	it is currently dumping (when dumping a subtree).

4.	Added the '-e' exclude inode option to dump. Thanks to
	Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.

5.	Added a REPORTING-BUGS file in order to provide a guide
	on how to correctly report a bug in dump/restore.

6.	Fixed a restore problem when restoring a hard link to an inode
	having the immutable or append-only attribute set. Thanks to
	Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.

7.	Fixed a compatibility problem between dumps made on little
	endian machines (the format was correct) and big endian 
	machines (the format was incorrect). This fix break the
	compatibility with the older dumps made on big endian 
	machines (sparc, m86k, ppc etc). For the first time in
	linux dump's history (I believe), the dumps made by *BSD, 
	Linux/alpha, Linux/sparc and Linux/x86 are compatible, 
	so interchangeable. Thanks to Rob Cermak
	<cermak@ahab.rutgers.edu> for submitting the bug and
	helping me test the fix.

8.	Fixed the way dump reports the remaining percent/time, if
	the number of blocks actually dumped exceeds the estimated
	number of blocks. Thanks to Jean-Paul van der Jagt 
	<jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.

Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
======================================================================

1.	Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
	<sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.

2.	Removed the requirement to build the RPM as root from the
	spec file. Thanks to Christian Weisgerber 
	<naddy@mips.rhein-neckar.de> for submitting this.

3.	Fixed a bug in dump related to the 'filetype' feature of ext2fs,
	causing dump to block when dumping really huge filesystems.
	Many thanks to Patrik Schindler <poc@pocnet.net> for 
	helping me find this bug.

4.	Fixed the treatment for an interrupt signal when dump access
	the remote tape through RSH. Thanks to Christian Weisgerber
	<naddy@mips.rhein-neckar.de> for providing the patch.

5.	Fixed a bug which was causing dump/restore to display
	garbage characters instead of the remote host name.

Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
=====================================================================

1.	Small fix in the dump man page. Thanks to Thorsten Kukuk 
	<kukuk@suse.de> for submitting the patch.

2.	Fix for the exit code when using the size estimate option of
	dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
	submitting the patch.

3.	Handle EINTR in atomical reads/writes in dump, which was causing
	dump to fail on some systems. Thanks to Eric Jergensen
	<eric@dvns.com> for reporting the bug and submitting the patch.

4.	Handle more than 16 characters for the device names in dumpdates.
	(up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
	tracking down the problem and proposing the solution.

5.	Fixed a bug in dump which prevented the creation of the
	dumpdates file when doing a 0-level dump without already
	having a dumpdates file. Thanks to Patrik Schindler 
	<poc@pocnet.net> for reporting the bug.

6.	Changed the way dump 'S' flag reports the size estimate
	from number of blocks into bytes (making it compatible
	with the Solaris version, and simplifying things for
	amanda users). Thanks to Jason L Tibbitts III 
	<tibbs@math.uh.edu> for reporting the bug.

7.	Fixed a compatibility problem in linux/alpha dump tape format.
	Now the linux/alpha dump are (again) compatible with the
	other dump formats. But this breaks compatibility with
	older dumps made on alpha. Thanks to Mike Tibor 
	<tibor@lib.uaa.alaska.edu> for helping me in finding this bug.  

Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
======================================================================

1.	Added a '--enable-kerberos' to configure.

2.	Added a 'S' option to dump which determines the amount of space
	that is needed to perform the dump without actually doing it, similar
	to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
	<cermak@ahab.rutgers.edu>.

3.	Added a 'M' multi-volume option to dump and restore which enables
	dumping to multiple files (useful when dumping to an ext2
	partition to make several dump files in order to bypass the 2GB
	file size limitation). The 'f' argument is treated as a prefix and
	the output files will be named <prefix>001, <prefix>002 etc. With
	the 'M' flag, restore automatically selects the right file without
	asking to enter a new tape each time.

4.	Fixed a memory leak which was causing dump to grow very big
	(270MB when dumping a 10GB filesystem...). Thanks to Jason 
	Fearon <jasonf@netrider.org.au> for reporting the bug.

Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
======================================================================

1.	Make configure test if the system glob routines support 
	extended syntax (ALTDIRFUNC). If not, use the internal glob
	routines instead of system ones. Thanks to Bernhard Sadlowski 
	<sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
	and helping me resolve this and other minor libc5 compiling
	glitches.

2.	Fix a problem when dumping a ext2fs with the 'filetype'
	feature enabled. Thanks to Patrick J. LoPresti 
	<patl@cag.lcs.mit.edu> for reporting the bug and to
	Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.

3.	Made the nodump flag work on directories. A directory which
	has the nodump flag gets never dumped, regardless of its
	contents.

4.	Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
	which allows dump on an active ext3 filesystem. However, this
	is a "quick and dirty" patch which enables backup of an ext3
	filesystem through the ext2 compatibility (by ignoring the
	NEEDS_RECOVERY bit). The journal file is not recognized and
	it is dumped (it should not). 

5.	Test the superblock compatibility flags when dumping, in order
	to be sure that we know how to deal with specific features.

Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
====================================================================

1.	Use lchown instead of chown, fixing a possible security problem 
	when restoring symlinks (a malicious user could use this
	to deliberately corrupt the ownership of important system files).
	Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
	this and providing the patch.

Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
====================================================================

1.	Put dump sources under CVS, added Id tags in all files so
	one can use 'ident' on binary files.

2.	Added the dump/restore version in the usage text so one can
	easily verify the version he is using.

3.	Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
	a va_start/va_end problem on linux-ppc (always call va_start
	va_end in pairs each time we use a vararg function).

4.	Added again the DT_* constants because old libc does not
	contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
	for submitting the bug report.

5.	Use ext2fs_llseek instead of llseek. With recent e2fsprogs
	this should enable dumping big (huge) filesystems.

6.	Added the RSH environment variable in order to be able to
	use a rsh replacement like ssh when doing remote backups (and
	bypass the security limitations of rcmd). Now you can do remote
	backups without being root (or making dump setuid root).

7.	Modified again the way dumpdates works. For incremental dumps,
	we need to read dumpdates even if we are not using 'u' option.
	Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
	this should work.

Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
===================================================================

1.	Removed the 'k' flag from the restore 'about' text if kerberos
	was not compiled in.

2.	Prototyped (f)setflags from e2fsprogs and corrected the calls
	to them (fsetflags takes a char*, setflags an open fd!).

3.	(f)setflags is called only if the flags aren't empty. If the
	file is a special file, a warning is printed, because changing
	flags implies opening the device. Normally, a special file
	should not have any flag... (Debian bug #29775, patch provided
	by Abhijit Dasgupta <abhijit@ans.net>).

4.	Made possible to dump a file system not mentioned in /etc/fstab.
	(Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).

5.	Changed the default behaviour to not create dumpdates
	unless 'u' option is specified. Removed the old "debian-patch"
	which provided the same thing. (Debian bug #38136, #33818).

6.	Removed all those dump*announce, since they were getting old...

7.	Added warning messages if dumpdates does not exist and
	when an inferior level dump does not exist (except for a level 0
	dump).

8.	Debugged the glob calls in interactive mode: restore used a 
	dirent struct which was different from the /usr/include/dirent.h
	one (this used to work, is it a glibc2 change?), so none of the 
	compat glob (which used /usr/include/dirent.h) or the system glob 
	worked. Restore use now the system dirent (and the system 
	DT_* constants), which are compatible with BSD ones.

9.	Added a configure flag (--with-dumpdatespath) to specify
	the location of dumpdates file. By default, it is 
	/etc/dumpdates.

10.	Added the "AUTHOR" and "AVAILABILITY" sections and 
	included the current date/version in man pages.

11.	Corrected the estimation of remaining time when
	the operator doesn't change the tapes quickly enough. This
	was an old bug, I thought I corrected it, and discovered
	that in fact it was corrected in two different places, so
	the results canceled each other...

Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
===================================================================

1.	Integrated multiple patches from RedHat, Debian and SuSE:

	- tweak dump/itime.c to not try to read dumpdates if the 'u' option 
	  isn't specified.
	- several fixes in the man pages.
	- update the default tape device to /dev/st0.
	- many updates for Linux Alpha (byte ordering, size_t etc).
	- buffer overruns.
	- use environment variable for TMPDIR (instead of /tmp).
	- use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
	- workaround egcs bug (RedHat bugs #4281 and #2989).
	- wire $(OPT) throughout Makefile's.

2.	Upgrade the dump revision to 1, making possible to dump filesystems
	made with e2fsprogs-1.15 or newer. Nothing seems to break...

3.	Fix some compile warnings, prototype all functions.

4.	Use glibc err/glob instead of internal compatibility
	routines (only if available).

5.	Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
	by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).

Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
======================================================================

1.	Integrated the changes from FreeBSD-3.1-RELEASE
	(mostly bug fixes, buffer overruns, dump has now an "automatic
	tape length calculation" flag, dump/restore can use kerberos now
	(this is NOT tested), use environment variables for TAPE and
	RMT etc.).

2.	Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)

3.	Corrected a bug in restore when using 'C' option with multi-volumes
	tapes (files splited accros two tapes give "size changed" errors
	when comparing).

4.	Corrected the long standing bug when dumping multiple tapes.
	This works for me, needs further testing.

Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
====================================================================

1.	Dump now runs correctly on kernels 2.1.x
	Fix made by Gerald Peters <gapeters@worldnet.att.net>

Changes between versions 0.4b2 and 0.4b3
========================================

1.	Use realpath() if available

2.	Report statistics

Changes between versions 0.4b1 and 0.4b2
========================================

1.	Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
	the patch)

2.	Fixed restore to make it able to read FreeBSD 2.x dumps again

3.	Fixed configure.in to correctly handle --enable-rmt

Changes between versions 0.3 and 0.4b1
======================================

1.	Integrated the changes from 4.4BSD-Lite2

2.	Integrated the patches from Debian and Red Hat

3.	Portability changes: use the __u32, __u16, __s32, and __s16 types

4.	Changed dump to use the Ext2fs library to get block addresses.  This
	should solve the endianness problem on SparcLinux.

5.	Created a configure.in file (shamelessly stolen from the e2fsprogs
	distribution's one) to use autoconf

6.	Fixed a few minor bugs

Changes between versions 0.2e and 0.2f
======================================

1.	Added the creation of named pipes (fifos) in restore.

2.	Added the -N flag in the restore manual page.

3.	Added the file kernel.patch which contains the llseek() optimization
	patch for 1.2.x kernels.

4.	Fixed a bug in the restoration of symbolic links: owner and group were
	not restored.

5.	Integrated some changes from FreeBSD 2.2.

6.	Added a call to ftruncate() after restoring each file to restore
	correctly files ending by a hole.

Changes between versions 0.2d and 0.2e
======================================

1.	Fixed a bug in the "set owner/mode" process.  Every file was restored
	with owner = root (0) and group = root/wheel/whatever (0).

Changes between versions 0.2c and 0.2d
======================================

1.	Dump is now able to backup 2GB+ filesystems.

2.	Dump and restore can now be linked as static binaries.

Changes between versions 0.2b and 0.2c
======================================

1.	Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.

Changes between versions 0.2a and 0.2b
======================================

1.	Really fixed the bug that I should have corrected in 0.2a.

2.	Enabled optimization again.

Changes between versions 0.2 and 0.2a
=====================================

1.	Disabled the optimization during compilation.

Changes between versions 0.1 and 0.2
====================================

1.	Fixed a bug in fstab.c which caused a null pointer to be stored in
	the fs_type field (actually, I modified the file fstab.c to make it
	use the mntent functions).

2.	Dump and restore now use a 4.3 BSD compatible dump format.  Backups
	made by dump should be readable by the BSD restore and backups made
	by the BSD dump should be readable by restore.  Unfortunately, this
	means that the dump format has changed between version 0.1 and version
	0.2 :-(

3.	Dump is now able to backup a subtree, it is no longer limited to whole
	filesystems like the BSD version.

4.	Dump now uses ext2_llseek() so it is able to backup filesystems bigger
	than 2 GB.

Changes between versions 0.0 and 0.1
====================================

1.	Now create links rdump and rrestore during the `make install' step.

2.	Linux port specific bugs added to the manual pages

3.	Incorrect estimation of the number of tapes blocks fixed when doing
	incremental backups.

4.	Better ls-like format in restore in interactive mode.
