-version 1.19.1 (CVS)
+version 1.22 - Sergey Poznyakoff, 2009-03-05
+
+* Support for xz compression
+
+Tar uses xz for compression if one of the following conditions is met: 
+
+ 1. The option --xz or -J (see below) is used.
+ 2. The xz binary is set as compressor using --use-compress-program option.
+ 3. The file name of the archive being created ends in `.xz' and
+ auto-compress option (-a) is used.
+
+Xz is used for decompression if one of the following conditions is met: 
+
+ 1. The option --xz or -J is used.
+ 2. The xz binary is set as compressor using --use-compress-program option.
+ 3. The file is recognized as xz compressed stream data.
+
+* Short option -J reassigned as a short equivalent of --xz
+
+* New option -I
+
+The -I option is assigned as a short equivalent for
+--use-compress-program.
+
+* The --no-recursive option works in incremental mode.

+version 1.21 - Sergey Poznyakoff, 2008-12-27
+
+* 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,
+e.g.:
+
+   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.

+LVM snapshot).
+
+The `--check-device' option enables comparing device numbers.  This is
