Managing multiple platforms and versions

My game works on multiple platforms (ios, android), and at any given time, there might be multiple versions of the game out in the wild for each, that may require their own sets of bundles.

What is the best way to manage this? build a catalog & set of bundles for every possible version basically? This would be fine, I suppose, although I would guess a lot of bundles maybe redundant from version to version. Hard drive space is cheap, right?

Just looking for some general guidelines, and if anyone is willing to share their approach to this. Thanks!
