-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
A new release of tar, 1.15.1-2, is available.
NEWS:
=====
This is a new upstream release, with a new maintainer. Upstream changes
since the previous version, 1.13.25-7, are listed below, and can be found
in /usr/share/doc/tar-1.15.1/NEWS.
Additionally, for text files managed by tar (such as incremental listings,
as opposed to actual binary tar files), this version no longer forces \r\n
line endings on binary mounts. Also, it is now possible to use file lists
that have managed mount filenames including \r by using the --null option.
The testsuite passes for both binary and text mounts, so please report
any problems caused by this change.
DESCRIPTION:
============
GNU Tar is an archiver program. It is used to create and manipulate files
that are actually collections of many other files; the program provides
users with an organized and systematic method of controlling a large
amount of data. Despite its name, that is an acronym of "tape archiver",
GNU Tar is able to direct its output to any available devices, files or
other programs, it may as well access remote devices or files. The main
areas of usage for GNU Tar are: storage, backup and transportation.
UPDATE:
=======
To update your installation, click on the "Install Cygwin now" link on
the http://cygwin.com/ web page. This downloads setup.exe to your
system. Save it and run setup, answer the questions and pick up
'tar' from the 'Base' category (it should already be selected).
DOWNLOAD:
=========
Note that downloads from sources.redhat.com (aka cygwin.com) aren't
allowed due to bandwidth limitations. This means that you will need
to find a mirror which has this update, please choose the one nearest
to you: http://cygwin.com/mirrors.html
QUESTIONS:
==========
If you want to make a point or ask a question the Cygwin mailing
list is the appropriate place.

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
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 supercedes 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).
* Bugfixes:
** 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.
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.
