Hi
I know that it is a forum of development. so sorry in advance.

 But as packager I would want to know if it were possible to know the
innovationes that RPM 5,0 introduces in greater detail,
for example new tag, better dependency resolution, new and useful
command-line switches and so on

 As an example as far i know the support to the LZMA has been introduced
also in RPM 4.4.2 of the RHEL.1 (backported also this ? :=))

Thanks for your job
