+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.
+
+* Bug fixes.

+\f
+version 1.13.25 - Paul Eggert, 2001-09-26
+
+* Bug fixes.
+
+\f
+version 1.13.24 - Paul Eggert, 2001-09-22
+
+* New option --overwrite-dir.
+* Fixes for buffer overrun, porting, and copyright notice problems.
+* The message translations for Korean are available again.
+
+\f
+version 1.13.23 - Paul Eggert, 2001-09-13
+
+* Bug, porting, and copyright notice fixes.
+
+\f
+version 1.13.22 - Paul Eggert, 2001-08-29
+
+* Bug fixes.
+
+\f
+version 1.13.21 - Paul Eggert, 2001-08-28
+
+* Porting and copyright notice fixes.
+
+\f
+version 1.13.20 - Paul Eggert, 2001-08-27
+
+* Some bugs were fixed:
+ - security problems
+ - hard links to symbolic links
+
+* New option --recursion (the default) that is the inverse of --no-recursion.
+
+* New options --anchored, --ignore-case, --wildcards,
+ --wildcards-match-slash, and their negations (e.g., --no-anchored).
+ Along with --recursion and --no-recursion, these options control how
+ exclude patterns are interpreted.
+
+* The default interpretation of exclude patterns is now --no-anchored
+ --no-ignore-case --recursion --wildcards --wildcards-match-slash.
+ This is a quiet change to the semantics of --exclude. The previous
+ semantics were a failed attempt at backward compatibility but it
+ became clear that the semantics were puzzling and did not satisfy
+ everybody. Rather than continue to try to revive that dead horse we
+ thought it better to substitute cleaner semantics, with options so
+ that you can change the behavior more to your liking.
+
+* New message translations for Indonesian and Turkish.
+ The translation for Korean has been withdrawn due to encoding errors.
+ It will be reissued once those are fixed.
+
+\f
+version 1.13.19 - Paul Eggert, 2001-01-13
+
+* The -I option has been withdrawn, as it was buggy and confusing.
+ Eventually it is planned to be reintroduced, with the same meaning as -T.
+
+* With an option like -N DATE, if DATE starts with "/" or ".", it is taken
+ to be a file name; the last-modified time of that file is used as the date.
+
+\f
+version 1.13.18 - Paul Eggert, 2000-10-29
+
+* Some security problems have been fixed. 'tar -x' now modifies only
+ files under the working directory, unless you also specify an unsafe
+ option like --absolute-names or --overwrite.
+
+* The short name of the --bzip option has been changed to -j,
+ and -I is now an alias for -T, for compatibility with Solaris tar.
+
+* The manual is now distributed under the GNU Free Documentation License.
+
+* The new environment variable TAR_OPTIONS holds default command-line options.
+
+* The --no-recursion option now affects extraction too.
+
+* The wording in some diagnostics has been changed slightly.
+
+* Snapshot files now record whether each file was accessed via NFS.
+ The new file format is upward- and downward-compatible with the old.
+
+* New language supported: da.
+
+* Compilation by traditional (K&R) C compilers is no longer supported.
+ If you still use such a compiler, please use GCC instead.
+
+* This version of tar works best with GNU gzip test version 1.3 or later.
+ Please see <ftp://alpha.gnu.org/gnu/gzip/>.
+
+* 'tar --delete -f -' now works again.
+
+\f
+version 1.13.17 - Paul Eggert, 2000-01-07.
+
+* 'tar --delete -f -' is no longer allowed; it was too buggy.
+* Diagnostic messages have been made more regular and consistent.
+
+\f
+version 1.13.16 - Paul Eggert, 1999-12-13.
+
+* By default, tar now refuses to overwrite an existing file when
+ extracting files from an archive; instead, it removes the file
+ before extracting it. If the existing file is a symbolic link, the
+ link is removed and not the pointed-to file. There is one
+ exception: existing nonempty directories are not removed, nor are
+ their ownerships or permissions extracted. This fixes some
+ longstanding security problems.
+
+ The new --overwrite option enables the old default behavior.
+
+ For regular files, tar implements this change by using the O_EXCL
+ option of 'open' to ensure that it creates the file; if this fails, it
+ removes the file and tries again. This is similar to the behavior of
+ the --unlink-first option, but it is faster in the common case of
+ extracting a new directory.
+
+* By default, tar now ignores file names containing a component of '..'
+ when extracting, and warns about such file names when creating an archive.
+ To enable the old behavior, use the -P or --absolute-names option.
+
+* Tar now handles file names with multibyte encodings (e.g., UTF-8, Shift-JIS)
+ correctly. It relies on the mbrtowc function to handle multibyte characters.
+
+* The file generated by -g or --listed-incremental now uses a format
+ that is independent of locale, so that users need not worry about
+ locale when restoring a backup. This is needed for proper support
+ of multibyte characters. Old-format files can still be read, and
+ older versions of GNU tar can read new-format files, unless member
+ names have multibyte chars.
+
+* Many diagnostics have been changed slightly, so that file names are
+ now output unambiguously. File names in diagnostics now are either
+ `quoted like this' (in the default C locale) or are followed by
+ colon, newline, or space, depending on context. Unprintable
+ characters are escaped with a C-like backslash conventions.
+ Terminating characters (e.g., close-quote, colon, newline)
+ are also escaped as needed.
+
+* tar now ignores socket files when creating an archive.
+ Previously tar archived sockets as fifos, which caused problems.
+
+\f
+version 1.13.15 - Paul Eggert, 1999-12-03.
+
+* If a file's ctime changes when being archived, report an error.
+ Previously tar looked at mtime, which missed some errors.
+
+\f
+version 1.13.14 - Paul Eggert, 1999-11-07.
+
+* New translations ja, pt_BR.
+* New options --help and --version for rmt.
+* Ignore Solaris door files when creating an archive.
+
+\f
+version 1.13.13 - Paul Eggert, 1999-10-11.
+
+* Invalid headers in tar files now elicit errors, not just warnings.
+* 'tar --version' output conforms to the latest GNU coding standards.
+* If you specify an invalid date, 'tar' now substitutes (time_t) -1.
+* 'configure --with-dmalloc' is no longer available.
+
+\f
+version 1.13.12 - Paul Eggert, 1999-09-24.
+
+* 'tar' now supports hard links to symbolic links.
+
+* New options --no-same-owner, --no-same-permissions.
+
+* --total now also outputs a human-readable size, and a throughput value.
+
+* 'tar' now uses two's-complement base-256 when outputting header
+ values that are out of the range of the standard unsigned base-8
+ format. This affects archive members with negative or huge time
+ stamps or uids, and archive members 8 GB or larger. The new tar
+ archives cannot be read by traditional tar, or by older versions of
+ GNU tar. Use the --old-archive option to revert to the old
+ behavior, which uses unportable representations for negative values,
+ and which rejects large files.
+
+* On 32-bit hosts, 'tar' now assumes that an incoming time stamp T in
+ the range 2**31 <= T < 2**32 represents the negative time (T -
+ 2**32). This behavior is nonstandard and is not portable to 64-bit
+ time_t hosts, so 'tar' issues a warning.
+
+* 'tar' no longer gives up extracting immediately upon discovering
+ that an archive contains garbage at the end. It attempts to extract
+ as many files as possible from the good data before the garbage.
+
+* A read error now causes a nonzero exit status, not just a warning.
+
+* Some diagnostics have been reworded for consistency.
+
+\f
+version 1.13.11 - Paul Eggert, 1999-08-23.
+
+* The short name of the --bzip option has been changed to -I,
+ for compatibility with paxutils.
+
+* -T /dev/null now matches nothing; previously, it matched anything
+ if no explicit operands were given.
+
+* The '--' option now works the same as with other GNU utilities;
+ it causes later operands to be interpreted as file names, not options,
+ even if they begin with '-'.
+
+* For the --newer and --after-date options, the table of time zone
+ abbreviations like 'EST' has been updated to match current practice.
+ Also, local time abbreviations are now recognized, even if they are
+ not in tar's hardwired table. Remember, though, that you should use
+ numeric UTC offsets like '-0500' instead of abbreviations like
+ 'EST', as abbreviations are not standardized and are ambiguous.
+
+\f
+version 1.13.10 - Paul Eggert, 1999-08-20.
+
+* 'tar' now uses signed base-64 when outputting header values that are
+ out of the range of the standard unsigned base-8 format. [This
+ change was superseded in 1.13.12, described above.]
+
+\f
+version 1.13.9 - Paul Eggert, 1999-08-18.
+
+* 'tar' now writes two zero blocks at end-of-archive instead of just one.
+ POSIX.1 requires this, and some other 'tar' implementations check for it.
+
+* 'tar' no longer silently accepts a block containing nonzero checksum bytes
+ as a zero block.
+
+* 'tar' now reads buggy tar files that have a null byte at the start of a
+ numeric header field.
+
+\f
+version 1.13.8 - Paul Eggert, 1999-08-16.
+
+* For compatibility with traditional 'tar', intermediate directories
+ created automatically by root are no longer given the uid and gid of
+ the original file or directory.
+
+\f
+version 1.13.7 - Paul Eggert, 1999-08-14.
+
+* --listed-incremental and --newer are now incompatible options.
+
+* When creating an archive, leading './' is no longer stripped,
+ to match traditional tar's behavior (and simplify the documentation).
+
+* --diff without --absolute-names no longer falls back on absolute names.
+
+\f
+version 1.13.6 - Paul Eggert, 1999-08-11.
+
+* An --exclude pattern containing / now excludes a file only if it matches an
+ initial prefix of the file name; a pattern without / continues to
+ exclude a file if it matches any file name component.
+
+* The protocol for talking to rmt has been extended slightly.
+ Open flags are now communicated in symbolic format as well as numeric.
+ The symbolic format (e.g., "O_WRONLY|O_CREAT|O_TRUNC") is for portability
+ when rmt is operating on a different operating system from tar.
+ The numeric format is retained, and rmt uses it if symbolic format is absent,
+ for backward compatibility with older versions of tar and rmt.
+
+* When writing GNU tar format headers, tar now uses signed base-64
+ for values that cannot be represented in unsigned octal.
+ This supports larger files (2**66 - 1 bytes instead of 2**33 - 1 bytes),
+ larger uids, negative time stamps, etc.
+
+* When extracting files with unknown ownership, tar now looks up the
+ uid and gid "nobody" on hosts whose headers do not define UID_NOBODY
+ and GID_NOBODY, and falls back on uid/gid -2 if there is no "nobody".
+
+* tar -t --numeric-owner now prints numeric uids and gids, not symbolic.
+
+* New option -y or --bzip2 for bzip2 compression, by popular request.
+
+\f
+version 1.13.5 - Paul Eggert, 1999-07-20.
+
+* Do the delayed updates of file metadata even after a fatal error.
+
+\f
+version 1.13.4 - Paul Eggert, 1999-07-20.
+
+* Do not chmod unless we are root or the -p option was given;
+ this matches historical practice.
+
+\f
+version 1.13.3 - Paul Eggert, 1999-07-16.
+
+* A path name is excluded if any of its file name components matches an
+ excluded pattern, even if the path name was specified on the command line.
+ Also see 1.13.6 for later changes in this area.
+
+\f
+version 1.13.2 - Paul Eggert, 1999-07-14.
+
+* Bug reporting address changed to <bug-tar@gnu.org>.
+
+\f
+version 1.13.1 - Paul Eggert, 1999-07-12.
+
+* Bug fixes only.
+\f
+version 1.13 - Paul Eggert, 1999-07-08.
+
+* Support for large files, e.g., files larger than 2 GB on many 32-bit hosts.
+ Also, support for larger uids, device ids, etc.
+* Many bug fixes and porting fixes.
+* This release is only for fixes. A more ambitious test release,
+ with new features, is available as part of the paxutils. Please see:
+ ftp://alpha.gnu.org/gnu/paxutils/
+ The fixes in this release are intended to be merged with paxutils
+ at some point, but they haven't been merged yet.
+* An interim GNU tar alpha had new --bzip2 and --ending-file options,
+ but they have been removed to maintain compatibility with paxutils.
