Subject: - 5.0 - urpmf, urpmq:   o use xml info instead of hdlist when
 possible     o "urpmq -l" is faster (3x)     o "urpmf -l" is slower (1.5x)   
  o "urpmf --sourcerpm" is much faster     o see "xml-info" option in
 urpmi.cfg(5) to see when those files are downloaded     o new require: perl
 module XML::LibXML - urpmq:   o use rpm file instead of hdlist/xml-info when
 file is local   o use URPM::Package->changelogs (need perl-URPM 3.06) -
 urpmi.update, urpmi.addmedia, urpmi.removemedia:   o drop hdlist support
 replaced with xml media_info     (this imply file-deps are correctly handled,
 see genhdlist2(1)) - urpmi.addmedia   o new --xml-info option
