Is it possible to Upgrade from one release to another using the update center?
Q: Is it possible to upgrade from (for example) NetBeans IDE 6.7.1 to 6.8, or from a beta to a milestone to a final release, using the update center?
A: No, this is not possible. For a new release, you must download a new installer from the download page. http://netbeans.org/downloads/ However it is possible to upgrade from one release to a nightly build, even inadvertently, if you add the "Latest Development" update centers, so please, be carefull when using them.
