Update Release Notes summarize changes made in all 1.6.0 update releases. Note that bug fixes are cumulative, that is, bug fixes in previous update versions are included in subsequent update versions.
The version numbers are given for each update release, complete with build number. To determine the version of your JDK software, use the following command:
