I think the documentation is fine, nothing in it indicates that what I'm looking for is supported. That's why I was asking if it's possible to reconstruct the v5.9-rc1 source tree from the v5.8 source tree plus a v5.8..v5.9-rc1 bundle at least theoretically. Poking a little further, I see that the bundle depends on v5.8 and all the ancestor commits of v5.8 that were merged into v5.9-rc1, which only makes sense now. The bundle doesn't contain any of the objects coming from those commits, so there's simply not enough information there for what I was trying to achieve. Thanks, Andreas
