Description of problem:
PackageKit-zif doesn't tell which old version is being replaced by the update. This is useful information, e.g. does this foo-4.0.0-1.fc15 update replace foo-3.1.3-37.fc15 or foo-4.0.0-0.8.rc5.fc15? (In the former case, the update is likely to be more risky than in the latter case.)
Version-Release number of selected component (if applicable):
PackageKit up to at least 0.6.18/0.7.0
Steps to Reproduce:
1. Check the update information displayed by the PackageKit GUI. (At least Apper/KPackageKit displays this information.)
No information on which previous version is being replaced is provided.
Information on which previous version is being replaced is provided.
The yum backend supports this feature.
In F20 and rawhide the zif backend has been replaced by hawkey.
