I am pleased to announce the release of GNU tar version 1.21.

Here are the compressed sources:    (2.9MB)   (2.0MB)   (4.3MB)   (2.9MB)

Here are the GPG detached signatures[*]:

Here are the MD5 and SHA1 checksums:

[*] You can use either of the above signature files to verify that
the corresponding file (without the .sig suffix) is intact.  First,
be sure to download both the .sig file and the corresponding tarball.
Then, run a command like this:

  gpg --verify tar-1.21.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver --recv-keys 55D0C732

and rerun the `gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.61
  Automake 1.10.1
  Gnulib-tool 0.0.1317-d51f4-modified

Please email bugs or suggestions to <address@hidden>.

The list of user-visible changes follows:

* New short option -J

A shortcut for --lzma.

* New option --lzop

* New option --no-auto-compress

Cancels the effect of previous --auto-compress (-a) option.

* New option --no-null

Cancels the effect of previous --null option.

* Compressed format recognition

If tar is unable to determine archive compression format, it falls
back to using archive suffix to determine it.

* VCS support.

Using --exclude-vcs handles also files used internally by Bazaar,
Mercurial and Darcs.

* Transformation scope flags

Name transformation expressions understand additional flags that
control type of archive members affected by them.  The flags are:

 - r
   Apply transformation to regular archive members.

 - s
   Apply transformation to symbolic link targets.

 - h  
   Apply transformation to hard link targets.

Corresponding upper-case letters negate the meaning, so that
`H' means ``do not apply transformation to hard link targets.''

The scope flags are listed in the third part of an `s' expression,

   tar --transform 's|^|/usr/local/|S'

Default is `rsh', which means that transformations are applied to
both regular archive members and to the targets of symbolic and hard
links.  If several transform expressions are used, the default flags
can be changed using `flags=' statement before the expressions, e.g.:

   tar --transform 'flags=S;s|^|/usr/local/|S'

* Bugfixes

** The --null option disabled handling of tar options in list files.  This
is fixed.
** Fixed record size autodetection.  If detected record size differs from
the expected value (either default, or set on the command line), tar
always prints a warning if verbosity level is set to 1 or greater,
i.e. if either -t or -v option is given.
