-Changes between versions 0.4b7 and 0.4b8 (released ???????????????)
+Changes between versions 0.4b17 and 0.4b18 (released ??????????????)
+====================================================================
+
+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.
+
+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)
