History: Upgrade to 5.1

Hi!

I noticed that in installation of tiki 5.1 with new db, menu layout have been improved (passing the mouse over elements are explosed), as well as the tikiwiki logo has been changed (is the same you can see during the installation) and incons have been added for clar cache and edit look and feel.

Instead, with my old db (converted by tiki install) nothing changed.

What can i do?

Thank
