Javadogs,


It's time to decide the broad outline of the JDO 2 maintenance release. I have put into the ChangeLogs all the features that I know of that we have discussed including. If there are any missing items, please reply.

One rather large decision is whether to require JDK 1.5 for the release. I think there are three options, since part of the change requires JDK 1.5: annotations, Enum, and signature changes for generics.

1. Require JDK 1.5 for the 2.1 maintenance release.

Pro: Least amount of work for everyone. Easiest to explain, package, and document.

Con: All the users who want the features of JDO 2.1 and can't move to JDK 1.5 (actually, the only significant feature that doesn't require 1.5 is subqueries).

2. Split the current maintenance release into two maintenance releases. Do the first maintenance release with no JDK 1.5 changes, and follow up in six months with another release that includes the 1.5 content.

Pro: Users get subqueries without going to JDK 1.5

Con: No annotation, enum, or JPA support for another 6 to 8 months

3. Split the maintenance release into two parts, one of which only requires JDK 1.3, and the other part which requires 1.5. Ship two sets of jar files for at least the api20 jar and tck20 jar, with different dependencies. 

Pro: Users get exactly what they want, and only have a dependency on 1.5 if they want to use 1.5 features

Con: A lot more work, harder to package, document, and use, more maven dependencies, more packages and jar files. The project is under-resourced to do this in a timely way.

Please let me know which of these options you are willing to help with.
