Do I need to re-install to go from 10.04 beta to 10.04 stable

[TSH]

I've only ever used current stable versions of /x/buntu before, but a
couple of weeks ago I installed Studio 10.04 beta onto a spare HDD to
see what it was like, and now want to stick with it.

Will doing an update result in the latest stable version just released,
or do I need to reinstall?
