I would recommend against using detailed numbered versions for this. That couples you to bug fix patches/updates in the external libraries and creates a very high versioning effort.
In Seaside we use release3 release30 release31 instead of stable. Release3 introduced a different packaging, and 31 has some interface changes. We can now safely promote a new version to stable without having to update all configurations using seaside.
This reduces the versioning effort, at some loss in reproducibility. For that, separate snapshots are perfect.
