+1 on generics
+99 on package-name change.

The ASM project (org.objectweb.asm) changes their API significantly with
major releases, but do not change the package name. And it causes major
pain. For example, the following libs all require specific versions of ASM:
 * hibernate
 * drools
 * spring AOP (via cglib)
 * groovy

I've got an app that uses all of the above, and it was very difficult to
get it working. The only thing that saved me is that the groovy and
cglib projects provide variants that repackage ASM internally (renaming
the package). Even with that, I'm still stuck on asm 2.2.3 for my code
when I'd rather be using 3.1.x, just because I cannot use 3.1.x without
breaking one of the other libs I need.

So if a new project release is not backwards-compatible, please change
the package name.
