+* New option --no-auto-compress
+
+Cancels the effect of previous --auto-compress (-a) option.
+
+* Compressed format recognition
+
+If tar is unable to determine archive compression format, it falls

+
+version 1.20 - Sergey Poznyakoff, 2008-04-14
+
+* 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, ttyout=string, exec=cmdline, 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. See
+chapter 3.8 "Checkpoints" for a complete description.
+
+* New options --no-check-device, --check-device.
+
+The `--no-check-device' option disables comparing device numbers during
+preparatory stage of an incremental dump. This allows to avoid
+creating full dumps if the device numbers change (e.g. when using an
+LVM snapshot).
+
+The `--check-device' option enables comparing device numbers. This is
+the default. This option is provided to undo the effect of the previous
+`--no-check-device' option, e.g. if it was set in TAR_OPTIONS
+environment variable.
+
+* 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').
+
+Filename transformations are applied to symbolic link targets
+during both creation and extraction. Tar 1.19 used them only
+during extraction.
+
+For a detailed description, see chapter 6.7 "Modifying File and Member
+Names".
+
+* 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.
+
+* Incremental archives
+
+Improved (sped up) extracting from incremental archives.
+
+* Bugfixes.
+** Fix bug introduced in version 1.19: tar refused to update non-existing
+archives.
+
+\f
+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.
+
+\f
+version 1.15.91 - Sergey Poznyakoff, 2006-06-16
+
+* Incompatible changes
+
+** Globbing
+
+Previous versions of GNU tar assumed shell-style globbing when
+extracting from or listing an archive. For example:
+
+ tar xf foo.tar '*.c'
+
+would extract all files whose names end in '.c'. This behavior
+was not documented and was incompatible with traditional tar
+implementations. Therefore, starting from this version, GNU tar
+no longer uses globbing by default. For example, the above invocation
+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.
+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
+ --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
+command line and that of the exclusion patterns (given with --exclude
+and --exclude-from options). The defaults are:
+
+ 1. For member names: --no-wildcards --anchored
+ 2. For exclusion patterns: --wildcards --no-anchored --wildcards-match-slash
+
+The options can appear multiple times in the command line, thereby
+changing the way command line arguments are interpreted. For example,
+to use case-insensitive matching in exclude patterns and to revert to
+case-sensitive matching for the rest of command line, one could write:
+
+ tar xf foo.tar --ignore-case --exclude-from=FILE --no-ignore-case file.name
+
+** 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
+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.
+
+\f
+version 1.15.90 - Sergey Poznyakoff, 2006-02-19
+
+* New features
+
+** Any number of -T (--files-from) options may be used in the command line.
+The file specified with -T may include any valid `tar' options,
+including another -T option.
+Compatibility note: older versions of tar would only recognize -C
+as an option name within the file list file. Now any file whose name
+starts with - is handled as an option. To insert file names starting with
+dash, use the --add-file option.
+
+** List files containing null-separated file names are detected and processed
+automatically. It is no longer necessary to give the --null option.
+
+** New option --no-unquote disables the unquoting of input file names.
+This is useful for processing output from `find dir -print0'.
+An orthogonal option --unquote is provided as well.
+
+** New option --test-label tests the archive volume label.
+If an argument is specified, the label is compared against its value.
+Tar exits with code 0 if the two strings match, and with code 2 if
+they do not.
+
+If no argument is given, the --verbose option is implied. In this case,
+tar prints the label name if present and exits with code 0.
+
+** New option --show-stored-names. When creating an archive in verbose mode,
+it lists member names as stored in the archive, i.e., with any eventual
+prefixes removed. The option is useful, for example, while comparing
+`tar cv' and `tar tv' outputs.
+
+** New option --to-command pipes the contents of archive members to the
+specified command.
+
+** New option --atime-preserve=system, which uses the O_NOATIME feature
+of recent Linux kernels to avoid some problems when preserving file
+access times.
+
+** New option --delay-directory-restore delays restoring modification times
+and permissions of extracted directories until the end of extraction.
+This is necessary for restoring from archives with unusual member
+ordering (in particular, those created with --no-recursion option).
+This option is implied when restoring from incremental archives.
+
+** New option --restrict prohibits use of some potentially harmful tar
+options. Currently it disables '!' escape in multi-volume name menu.
+
+** New options --quoting-style and --quote-chars control the way tar
+quotes member names on output. The --quoting-style takes an argument
+specifying the quoting style to use (literal, shell, shell-always,
+c, escape, locale, clocale). The argument to --quote-chars is a string
+specifying characters to quote, even if the selected quoting style
+would not quote them otherwise. The option --no-quote-chars is
+provided to disable quoting certain characters.
+
+** The end-of-volume script (introduced with --info-script option) can
+get current archive name from the environment variable TAR_ARCHIVE and
+the volume number from the variable TAR_VOLUME. It can alter the
+archive name by writing new name to the file descriptor 3.
+
+** Better support for full-resolution time stamps. Tar cannot restore
+time stamps to full nanosecond resolution, though, until the kernel
+guys get their act together and give us a system call to set file time
+stamps to nanosecond resolution.
+
+** The -v option now prints time stamps only to 1-minute resolution,
+not full resolution, to avoid using up too many output columns.
+Nanosecond resolution is now supported, but that would be too much.
+
+* Bug fixes
+
+** Allow non-option arguments to be interspersed with options.
+** When extracting or listing archives in old GNU format, tar
+used to read an extra block of data after a long name header
+if length of the member name was divisible by block size (512).
+Consequently, the file pointer was set off and the next member
+was not processed correctly.
+** Previous version created invalid archives when files shrink
+during reading.
+** Compare mode (tar d) hung when trying to compare file contents.
+** Previous versions in certain cases failed to restore directory
+modification times.
+** When creating an archive, do not attempt to store files whose
+meta-data cannot be stored in the header due to format limitations
+(for ustar and v7 formats).
+** The --version option now also outputs information about copyright,
+license, and credits. This reverts to the behavior of tar 1.14 and
+earlier, and conforms to the GNU coding standards. The --license (-L)
+option introduced in tar 1.15 has been removed, since it's no longer
+needed.
+
+\f
+version 1.15.1 - Sergey Poznyakoff, 2004-12-21
+
+This version fixes a bug introduced in 1.15 which caused
+tar to refuse to extract files from standard input.
+
+\f
+version 1.15 - Sergey Poznyakoff, 2004-12-20
+
+* Compressed archives are recognised automatically, it is no longer
+necessary to specify -Z, -z, or -j options to read them. Thus, you can
+now run `tar tf archive.tar.gz'.
+
+* When restoring incremental dumps, --one-file-system option
+prevents directory hierarchies residing on different devices
+from being purged.
+
+With the previous versions of tar it was dangerous to create
+incremental dumps with --one-file-system option, since they
+would recursively remove mount points when restoring from the
+back up. This change fixes the bug.
+
+* Renamed --strip-path to --strip-components for consistency with
+the GNU convention.
+
+* Skipping archive members is sped up if the archive media supports
+seeks.
+
+* Restore script starts restoring only if it is given --all (-a) option,
+or some patterns. This is to prevent accidental restores.
+
+* `tar --verify' prints a warning if during archive creation some of
+the file names had their prefixes stripped off.
+
+* New option --exclude-caches instructs tar to exclude cache directories
+automatically on archive creation. Cache directories are those
+containing a standardized tag file, as specified at:
+
+ http://www.brynosaurus.com/cachedir/spec.html
+
+* New configure option --with-rmt allows to specify full path name to
+the `rmt' utility. This supersedes DEFAULT_RMT_COMMAND variable
+introduced in version 1.14
+
+* New configure variable DEFAULT_RMT_DIR allows to specify the directory
+where to install `rmt' utility. This is necessary since modifying
+--libexecdir as was suggested for version 1.14 produced a side effect: it
+also modified installation prefix for backup scripts (if
+--enable-backup-scripts was given).
+
+* Bug fixes:
+** Fixed flow in recognizing files to be included in incremental dumps.
+** Correctly recognize sparse archive members when used with -T option.
+** GNU multivolume headers cannot store filenames longer than 100 characters.
+Do not allow multivolume archives to begin with such filenames.
+** If a member with link count > 2 was stored in the archive twice,
+previous versions of tar were not able to extract it, since they
+were trying to link the file to itself, which always failed and
+lead to removing the already extracted copy. Preserve the first
+extracted copy in such cases.
+** Restore script was passing improper argument to tar --listed option (which
+didn't affect the functionality, but was logically incorrect).
+** Fixed verification of created archives.
+** Fixed unquoting of file names containing backslash escapes (previous
+versions failed to recognize \a and \v).
+** When attempting to delete a non-existing member from the archive, previous
+versions of tar used to overwrite last archive block with zeroes.
+
+\f
+version 1.14 - Sergey Poznyakoff, 2004-05-11
+
+* Added support for POSIX.1-2001 and ustar archive formats.
+* New option --format allows to select the output archive format
+* The default output format can be selected at configuration time
+ by presetting the environment variable DEFAULT_ARCHIVE_FORMAT.
+ Allowed values are GNU, V7, OLDGNU and POSIX.
+* New option --strip-path allows to cut off a given number of
+ path elements from the name of the file being extracted.
+
+* New options --index-file, --no-overwrite-dir. The --overwrite-dir
+ option is now the default; use --no-overwrite-dir if you prefer
+ the previous default behavior.
+
+* The semantics of -o option is changed. When extracting, it
+ does the same as --no-same-owner GNU tar option. This is compatible
+ with UNIX98 tar. Otherwise, its effect is the same as that of
+ --old-archive option. This latter is deprecated and will be removed
+ in future.
+
+* New option --check-links prints a message if not all links are dumped
+ for a file being archived. This corresponds to the UNIX98 -l option.
+ The current semantics of the -l option is retained for compatibility
+ with previous releases, however such usage is strongly deprecated as
+ the option will change to its UNIX98 semantics in the future releases.
+
+* New option --occurrence[=N] can be used in conjunction with one of
+ the subcommands --delete, --diff, --extract or --list when a list of
+ files is given either on the command line or via -T option. This
+ option instructs tar to process only the Nth occurrence of each named
+ file. N defaults to 1, so `tar -x -f archive --occurrence filename'
+ extracts the first occurrence of `filename' from `archive'
+ and terminates without scanning to the end of the archive.
+
+* New option --pax-option allows to control the handling of POSIX
+ keywords in `pax' extended headers. It is equivalent to `pax'
+ -o option.
+
+* --incremental and --listed-incremental options work correctly on
+ individual files, as well as on directories.
+
+* New scripts: backup (replaces old level-0 and level-1) and restore.
+The scripts are compiled and installed if --enable-backup-scripts
+option is given to configure.
+
+* By default tar searches "rmt" utility in "$prefix/libexec/rmt",
+which is consistent with the location where the version of "rmt"
+included in the package is installed. Previous versions of tar
+used "/etc/rmt". To install "rmt" to its traditional location,
+run configure with option --libexecdir=/etc. Otherwise, if you
+already have rmt installed and wish to use it, instead of the
+shipped in version, set the variable DEFAULT_RMT_COMMAND to
+the full path name of the utility, e.g., ./configure
+DEFAULT_RMT_COMMAND=/etc/rmt.
+
+Notice also that the full path name of the "rmt" utility to
+use can be set at runtime, by giving option --rmt-command to
+tar.
+
+* Removed obsolete command line options:
+** --absolute-paths superseded by --absolute-names
+** --block-compress is not needed any longer
+** --block-size superseded by --blocking-factor
+** --modification-time superseded by --touch
+** --read-full-blocks superseded by --read-full-records
+** --record-number superseded by --block-number
+** --version-control superseded by --backup
+
+* New message translations fi (Finnish), gl (Galician), hr (Croatian),
+ hu (Hungarian), ms (Malaysian), nb (Norwegian), ro (Romanian), sk
+ (Slovak), zh_CN (Chinese simplified), zh_TW (Chinese traditional).
+ The code 'no' for Norwegian (Bokmål) has been withdrawn; use 'nb' instead.
