Hibernate3 adds the ability to pre-define filter criteria and attach those filters at both a class and a collection level. What's a pre-defined filter criteria? Well, it's the ability to define a limit clause very similiar to the existing where attribute available on the class and various collection elements. Except these filter conditions can be parameterized! The application can then make the decision at runtime whether given filters should be enabled and what their parameter values should be.

I've seen three or four ORM tool comparisons in the last three weeks; on some weblogs, on our forum and I've even been part in several decisions.

I just released 2.1.2 . This is a maintenence release, meaning no especially exciting new features (the interesting work is all going on in the 2.2 branch). However there are some small changes that might make a big performance difference in certain specific cases, especially if you are using a second-level cache. I'm hoping that this release brings the 2.1 branch to the same level of maturity that we were able to achieve with 2.0.3.
