Assuming your product has the following dependency structure (where each item
in the tree is a p2 IU):
Your product 1.0
|--> CDT 5.0.1
|---> Platform 3.7.1
|--> RSE 2.0.0
|---> Platform 3.7.1
|--> Platform 3.7.1
then you will have to create a new version of the "Your product" IU that points
at new version of the pieces.
Your product 1.1
|--> CDT 5.0.2
|---> Platform 3.7.2
|--> RSE 2.0.0
|---> Platform 3.7.2
|--> Platform 3.7.2
This structure gives you complete control over what your user gets since when
you publish a new update, the user sees that there is an update to "Your
product" and not the individual pieces he does not want to know about. Note
that even though the product version has changed only the bundles that have
actually been changed will be downloaded.
