nothing special, just some news:

Of course the compression comes at a cost - it really chews CPU time.
For those using GNU tar, the man page is less than helpful, use:
    tar --xz -cf <archive.tar.xz> <source>
If there is an abbreviated option I can't see it.
    tar -xf <archive.tar.xz>
    tar -tf <archive.tar.xz>
