+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 1.15.92 - Sergey Poznyakoff, (CVS)
+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.
is now interpreted as a request to extract from the archive the file
named '*.c'.
-To treat member names as globbing patterns, use --wildcards option.
+To treat member names as globbing patterns, use --wildcards option.
If you wish tar to mimic the behavior of versions up to 1.15.90,
add --wildcards to the value of the environment variable TAR_OPTIONS.
The exact way in which tar interprets member names is controlled by the
following command line options:
- --wildcards use wildcards
+ --wildcards use wildcards
--anchored patterns match file name start
--ignore-case ignore case
--wildcards-match-slash wildcards match `/'
Each of these options has a '--no-' counterpart that disables its
effect (e.g. --no-wildcards).
-These options affect both the interpretation of member names from
+These options affect both the interpretation of member names from
command line and that of the exclusion patterns (given with --exclude
and --exclude-from options). The defaults are:
** 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 option --transform allows to transform file names before storing them
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

** The --totals option can be used with any tar operation (previous versions
understood it only with --create). If an argument to this option is

** Previous version created invalid archives when files shrink

** Previous versions in certain cases failed to restore directory
modification times.
