Yesterday I decided to upgrade my ubuntu to the new version 8.04. According to the release schedule this is the Alpha5 so all new features are included. Despite being a alpha version I didn't have any problem during the upgrade process and everything seems to work fine. Now it is time to test it.
In order to do this, a new feature seems to be very useful, the automatic bugs report. As in Gnome, now when you get a crash in an application you can send a bug report in automatic way to ubuntu.

Another interesting feature is PolicyKit. Now you can run administrative applications as normal user and click in unlock button if you need to do an action that require root privileges.

Besides, Ubuntu 8.04 Alpha 5 include a beta of the new Gnome 2.22 and a beta of Firefox 3.0 as default browser.
You can also install Firefox 2 from Add/Remove programs and to have both versions installed. This is very useful because for example, the Add-ons that I use normally don't work in Firefox 3.0 yet.
