-version 1.14.91 - Sergey Poznyakoff, <DATE>
+version 1.15.2 (CVS version -- unreleased)
+
+* 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) hanged 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.

+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.

+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
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

correctly. It relies on the mbrtowc function to handle multibyte characters.
* The file generated by -g or --listed-incremental now uses a format
`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.
