Solarmetric "just" released Kodo 3.3.0 and there are some really nice features, mostly JDO2 based. First of, my favourite is Single Field Identity. With this you can have application identity on a single primary key field without writing a PrimaryKey class for it. So you can just define an attribute like "customerNumber" and define it as primary key. Thats it. Of course you can assign a Kodo sequence to it so it gets incremented.

I also like this new convenience Method:

 PersistenceManager.getObjectById (Class cls, Object value). 

Then we have Lifecycle Events without implementing callback Methods into the persistent classes. A nice, non-intrusive way of getting notifications about your persistent POJO states. I ve never used it so far but i sounds promising.

I hope that the JDO2 interfaces get published soon, so that one can use the original interfaces and replace the preview feature interfaces from the application code.
