  (fixes #31969). It may still fail in presence of conflicts
- allow running transaction with justdb option
- fix split_length > 1 
  (eg: "urpmi --split-length 2 a b c" will only install 2 pkgs)
- spec2srcheader: workaround parseSpec returning a header where ->arch is set
  to %{_target_cpu} whereas we really want a header similar to .src.rpm
  (see #32824)

Version 1.75 - 12 August 2007, by Pascal "Pixel" Rigaux

- fix dropping tags from rpm header.
  it hasn't work since MDK8.1 and rpm 4.0.

  a more recent version, but no obsolete between those packages.
  the fix is to revert commit from Aug 2002:

     request_packages_to_upgrade."

Version 1.65 - 22 June 2007, by Olivier Thauvin

  to be able to display name of uninstalled package in callback_uninst

  (need a fix in urpmi which rely on the $state->{rejected} 
   to upgrade (-U) b instead of installing (-i) it)

Version 1.60 - 8 March 2007, by Pascal "Pixel" Rigaux

- more debugging hooks
- create $urpm->packages_providing($name) and use it
- create $urpm->packages_by_name($name)

Version 1.59 - 1 March 2007, by Olivier Thauvin

- rpm 4.4.8 adaptions
- load rpm config files at module load, improve the mechanism

Version 1.58 - 14 February 2007, by Pascal "Pixel" Rigaux

- don't check signature and digest in ->traverse and ->traverse_tag
  (=> x15 speedup, ie 2.5 speedup on urpmi --auto-select and rpmdrake)

Version 1.57 - 9 February 2007, by Pascal "Pixel" Rigaux

- allow upgrading from noarch to x86_64 even if strict-arch

Version 1.56 - 19 January 2007, by Pascal "Pixel" Rigaux

- bug fix release
- fix "not selecting foo-1 since the more recent foo-1 is installed" causing
  urpmi to try to remove the package it wants to install (#28076)

Version 1.54 - 9 January 2007, by Pascal "Pixel" Rigaux

- if we have a choice between foo-1 and bar-1 and foo-2 is installed,
  prefering bar-1 instead of foo-1
  (otherwise we can hit: "the more recent foo-2 is installed, but does not
  provide xxx whereas foo-1 does", cf bug #27991)
- bar is needed, foo-1 does provide bar, installed foo-2 does not provide bar:
  do not let the algorithm use foo-2 as if it also provides bar
- allow understanding what ->resolve_requested is doing through a callback ($urpm->{debug_URPM})
- cleanup some code in ->resolve_requested
- make the documentation for ->is_arch_compat more clear
