In triaging a reported issue I ended up having to once again delve into investigating PostgreSQL BLOB suppport. So for the sake of posterity and for the sake of my swiss cheese memory I decided to record my findings here.
I am pleased to announce that we have just released Hibernate version 3.5.0-CR-1. As a refresher, Hibernate follows the JBoss versioing scheme where CR is a Candidate for Release (what many of you might call RC). The main stated goal of 3.5 is JPA 2 compliance. This is the first release we believe achieves that goal entirely. In fact we are in the process of certifying for standalone JPA 2 compliance and have integrated this CR into the imminent JBoss AS M2 release as part of their effort towards full Java EE 6 compliance.
