And partially because it hasn't been released...
The latest official release of xar is from 2007.

Codewise, the internal XAR is supposed to be
identical to xar-1.6.0 - once that is out.
(Similar to how XZ is supposed to be identical
to xz-5.0.0 once that is released as stable)

But for RPM 5.0.0 we went with XAR 1.5 and
LZMA SDK support, since those were released
and thus more readily available in distros...
(internally we have xar-1.6dev and xz-4.999)


I made another sync effort of the internal xar,
minus some pending changes like adding latest
liblzma or adding more checksums - that isn't
affecting RPM's current usage of libxar anyway.

It's now on HEAD (see http://rpm5.org/sources.php)
and a candidate for backporting to the 5.2 branch.
But by all means do continue to use XAR 1.5.2,
especially for the older platforms like RHEL 5.
