Hi!

Although I have been searching for a long time, I ended up with the
option of asking to you(JBoss Community) for the best answer!

In our company we have been using Hibernate 2.1.7c for a long time.
Now, it's time for some update (updating Hibernate and also
ourselves!).

I checked the latest release bundles and the list of
Bugs/Solutions(from the user/admins) page, which was also helpful but
not the best one I search for.

We want to use Hibernate's latest version 3.5.4 in our company, but we
first want to know the improvements coming through the last years,
actually from the version 2.1.7c to version 3.5.4.

Is it possible to send us a list (or something like that) of the
improvements and the things making our life easier from the version we
use(2.1.7c) to latest version(3.5.4)?

Thank you very much!
Have a good day.

Maybe you should better ask yourself what your requirements are and if a new hibernate version would fit those requirements instead of asking other people to guess what you might need.

Actually that's right. I apologize for asking too general question.
For example;
Please correct me if I'm mistaken, as far as I know Hibernate 3 does not support importing and exporting data. Are we now capable of importing/exporting data via Hibernate?
