2309	Tar 1.21	willimm	Matthew Burgess	"New version.

From NEWS:

New short option -J, an alias 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.
The 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 a s expression, e.g.:
$ tar --transform 's|^|/usr/local/|S'
          
The 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 placed before the expressions, e.g.:
$ tar --transform 'flags=S;s|^|/usr/local/|'
          
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 prints a warning if verbosity level is set to 1 or greater, i.e. if either -t or -v option is given."	task	closed	normal	7.0	Book	SVN	normal	fixed
