JPA 2.0 is not released yet, so can still change, but is getting closer to release.

Some of the enhancements are discussed here:

This link also links the spec and reference implementation.

The difference is 1.0. Unless you are doing fuzzy math, then it is approximately 1.0 plus or minus a couple hundredths.

2.0 - 1.0 = 1.0
