[Inkscape-user] How to upgrade to Inkscape 0.46

Greetings

Sorry, I seem to be always late to everything. Had no idea ver. 0.46 was already released. Is it fully stable? Could you please explain me how to upgrade to 0.46? Do I have to uninstall 0.45 and install 0.46? I'm a Windows (Vista) user. Thanks in advance.
