+version 1.19.1 (CVS)
+
+* New option --auto-compress (-a)
+
+With --create, selects compression algorithm basing on the suffix
+of the archive file name.
+
+* New option --lzma
+
+Selects LZMA compression algorithm
+
+* New option --hard-dereference
+
+During archive creation, dereferences hard links and stores the files
+they refer to, instead of creating usual hard link members (type '1').
+
+* New option --checkpoint-action
+
+This action allows to specify an action to be executed upon hitting a
+checkpoint. Recognized actions are: dot, echo (the default),
+echo=string, and sleep=value. Any number of `--checkpoint-action'
+options can be specified, the actions will be executed in order of
+their appearance in the command line.
+
+* The --transform option.
+
+Any number of `--transform' options can be given in the command line.
+The specified transformations will be applied in turn.
+
+The argument to `--transform' option can be a list of replace
+expressions, separated by a semicolon (as in `sed').
+
+* Info (end-of-volume) scripts
+
+The value of the blocking factor is made available to info and
+checkpoint scripts via environment variable TAR_BLOCKING_FACTOR.
+
+* Bugfixes.
+** Fix bug introduced in version 1.19: tar refused to update non-existing
+archives.

-version 1.15.91 - Sergey Poznyakoff, (CVS version)
+version 1.19 - Sergey Poznyakoff, 2007-10-10
+
+* New option --exclude-vcs
+
+Excludes directories and files, created by several widely used version
+control systems, e.g. "CVS/", ".svn/", etc.
+
+* --exclude-tag and --exclude-cache options
+
+The following options now work with incremental archives as well:
+
+ --exclude-caches
+ --exclude-caches-all
+ --exclude-tag
+ --exclude-tag-all
+ --exclude-tag-under
+
+* Fix handling of renamed files in listed incremental archives.
+
+Previous versions always stored absolute file names in rename
+records, even if -P was not used. This is fixed: rename records
+contain file names processed in accordance with the command line
+settings.
+
+* Fix --version output.
+
+* Recognition of broken archives.
+
+When supplied an archive smaller than 512 bytes in reading mode (-x,
+-t), the previous version of tar silently ignored it, exiting with
+code 0. It is fixed. Tar now issues the following diagnostic message:
+'This does not look like a tar archive', and exits with code 2.
+
+* Fix double-dot recognition in archive member names in case of duplicate '/.'.
+
+* Fix file padding in case of truncation of the input file to zero size.
+
+\f
+version 1.18 - Sergey Poznyakoff, 2007-06-29
+
+* Licensed under the GPLv3
+
+* Fixed several bugs in the testsuite
+
+\f
+version 1.17 - Sergey Poznyakoff, 2007-06-08
+
+* Fix archivation of sparse files in posix mode. Previous versions padded
+ sparse members with spurious zero blocks.
+
+* Fix operation of --verify --listed-incremental. Version 1.16.1 produced
+ a full dump when both options were given.
+
+* Fix --occurrence. In previous versions it continued scanning the archive
+ even though all requested members has already been extracted.
+
+* Scope of --transform and --strip-components options.
+
+In addition to affecting regular archive members, the --transform
+option affects hard and soft link targets and the --strip-components
+option affects hard link targets as well.
+
+* End-of-volume script can send the new volume name to tar by writing
+ it to the file descriptor stored in the environment variable `TAR_FD'.
+
+\f
+version 1.16.1 - Sergey Poznyakoff, 2006-12-09
+
+* New option --exclude-tag allows to specify "exclusion tag files", i.e.
+ files whose presence in a directory means that the directory should not
+ be archived.
+
+* The --exclude-cache option excludes directories that contain the
+ CACHEDIR.TAG file from being archived. Previous versions excluded
+ directory contents only, while the directories themselves were
+ still added to the archive.
+
+* Support for reading ustar type 'N' header logical records has been removed.
+ This GNU extension was generated only by very old versions of GNU 'tar'.
+ Unfortunately its implementation had security holes; see
+ <http://archives.neohapsis.com/archives/fulldisclosure/2006-11/0344.html>.
+ We don't expect that any tar archives in practical use have type 'N'
+ records, but if you have one and you trust its contents, you can
+ decode it with GNU tar 1.16 or earlier.
+
+* Race conditions have been fixed that in some cases briefly allowed
+ files extracted by 'tar -x --same-owner' (or plain 'tar -x', when
+ running as root) to be accessed by users that they shouldn't have been.
+
+\f
+version 1.16 - Sergey Poznyakoff, 2006-10-21
+
+* After creating an archive, tar exits with code 1 if some files were
+changed while being read. Previous versions exited with code 2 (fatal
+error), and only if some files were truncated while being archived.
+
+* New option --mtime allows to set modification times for all archive
+members during creation.
+
+* Bug fixes
+** Avoid running off file descriptors when using multiple -C options.
+** tar --index-file=FILE --file=- sent the archive to FILE, and
+the listing to stderr.

** Short option -l is now an alias of --check-links option, which complies
with UNIX98. This ends the transition period started with version 1.14.

+
* New features
-** New incremental snapshot file format keeps information about file names
+** New option --transform allows to transform file names before storing them
+in the archive or member names before extracting. The option takes a
+sed replace expression as its argument. For example,
+
+ tar cf foo.tar --transform 's,^,prefix/,'
+
+will add 'prefix/' to all file names stored in foo.tar.
+
+** --strip-components option works when deleting and comparing. In previous
+versions it worked only with --extract.
+
+** New option --show-transformed-names enables display of transformed file
+or archive. It generalizes --show-stored-names option, introduced in
+1.15.90. In particular, when creating an archive in verbose mode, it lists
+member names as stored in the archive, i.e., with any eventual prefixes
+removed and file name transformations applied. The option is useful,
+for example, while comparing `tar cv' and `tar tv' outputs.
+
+** New incremental snapshot file format keeps information about file names
as well as that about directories.
+** The --checkpoint option takes an optional argument specifying the number
+of records between the two successive checkpoints. Optional dot
+starting the argument intructs tar to print dots instead of textual
+checkpoints.
+
+** The --totals option can be used with any tar operation (previous versions
+understood it only with --create). If an argument to this option is
+given, it specifies the signal upon delivery of which the statistics
+is to be printed. Both forms of this option (with and without
+argument) can be given to in a single invocation of tar.
+
+* Bug fixes
+** Detect attempts to update compressed archives.
