Actually, i have some comments regarding the history myself.

1) it would be nice to have an API that would (given a history log) be
 able to tell whether a package install actually means an upgrade,
downgrade, or just plain install (the log only contains   install/remove).

2) similar thing is with the repos - they can change over time, so the
 repo alias contained in the 'install' log entry may not tell much
without looking at the history of that repo - again an API giving a
history of that repo would be nice.

3) function to compute rollback to some date (remove this, install that)?

4) We need to log installs/removes done by non-zypp tools (comparing
cached @System.solv and the current state).

5) function to extract "requested by" info for the upcoming sat solver
auto-remove feature.
