I have already spoken about them here and here . And here come the version 5.0 of the debugbar.
The new features concern essentially the possibilities of dynamic inspect of components of your page. I particularly appreciated the tab « compute style » that allows to inspect the style properties of an element in runtime (that is the resulting style after all the css rules and inline rules are applied).
It is thus one tools more and more succeeds that proposes us DebugBar. Just use it.
