Changes

For security reasons you are encouraged to upgrade to at least Update 11, see section the latest release.Bug Fixes of the Update Release Notesunder each release: http://java.sun.com/javase/6/webnotes/6u11.html. For performance reasons you could also upgrade to the newer Update 12, which in turn does not fix security issues other than Update 11: http://java.sun.com/javase/6/webnotes/6u12ReleaseNotes.html. However, if you're running JRE 6 Update 10 or onwards and haven't disabled automatic updates then JRE should automatically be downloading and installing updates.
