Not really. As we mentioned several times, sling follows a mixed
approach. Modules are released independently and sometimes a big bang
release with all bundles is created. For example, the "Sling Source
Package" in version 6 contains org.apache.sling.scripting.jsp in
version 2.0.14 but the latest released version of that one is 2.0.18.
Didn't see a combined source release for that one ...

At sling, we follow what we do at felix with the exception that we
sometimes do a big bang release which contains everything.

Karl
