Completely agree with Juergen. Hibernate2 is used much more widely than Hibernate1, IMO, so will take a lot longer to disappear. I don't like the idea of breaking existing package names. After all, the Hibernate developers have chosen to abandon backward compatibility--we = can't do a miracle and hide that in Spring.=20 -----Original Message----- From: spr...@li...

Subject: Re: [Springframework-developer] Re: Hibernate 3 We do certainly not intend to drop Hibernate2 any time soon: It's too ubiquitous, and will be for some time to come. BTW, we also support both iBATIS SQL Maps 1.3.1 and 2.0: There, we have two different APIs in different iBATIS packages, so both reside in our "orm.ibatis" package. =20 >From my point of view, let's simply create a new "orm.hibernate3" = package, and keep the old "orm.hibernate" package as-is for Hibernate 2.1. While renaming the old package might seem appropriate in terms of consistently applying the Hibernate version number, I don't believe it adds much = value: If it's still called "hibernate", we can simply point out that it refers = to classic Hibernate, i.e. 2.1. That gives us full backwards compatibility, just with add-on support for Hibernate3. =20 Finally, Hibernate3 is still alpha. I'm quite strongly against shipping support classes for alpha software, particularly if it's such a large = bunch as for Hibernate3. We can certainly add such classes as "orm.hibernate3" package to the sandbox, but they should remain there until there's at = least a beta release out. =20 Juergen =20 ________________________________ Von: spr...@li... im Auftrag = von Martin Kersten Gesendet: Mi 25.08.2004 04:18 An: spr...@li...

But that is a far bit=20 > away. I don't like droping Hibernate 2. You know it will cost some afford (aka money) to convert a project utilizing Hibernate2 to a project utilizing Hibernate3. So it is very likely to have projects, which work fine and = using Hibernate 2 to stay in that condition for a really long time. And so I = think the support should not be dropped anytime. At least a compatible = solution should be offered. I favour the package naming solution, mentioned earlier. Call the = package hibernate3 and rename the old one to hibernate2. So I guess things would become very clear and beside some renaming = nothing much has to be changed to convert an existing project to use the newest Spring release.
