For those of you who track these things, we are on Java SE 6, Sun's JRE is at version 6 Update 12.
The next JRE update of note will be 6u14 (in early access), which includes some handy performance impovements, the G1 collector (for use, but not yet the default collector), and some preparatory changes like loading anonymous classes which will turbo-charge dynamic languages in JDK 7.
And of course the next major update will be JDK 7, so you may be tracking the latest JDK 7 builds, which have been including API additions ahead of the release for some time. Like changes to the language model as Joe summarizes here. Or the new ability to close() a URLClassloader since b46 that Michael blogged about here.
Or, more significantly, the inclusion of latest draft version of JSR 203, in particular the new filesystem API, one of the larger features on the list for JDK 7.
