[Post] Add draft of CocoaPods 0.35 release post

I think, it would be helpful if you could explain here, why this Podfile would led to a conflict. If you know all these three specs, it's probably pretty obvious. e.g.:
>All three pods depend on different versions of their specs on different versions of AFNetworking.
>[…]
>If we would naively try to integrate the latest version of the first spec and go on from there, this would led to a conflict, because e.g. AFOAuth2Client depends on an older major version, which isn't API-compatible with the latest major release of AFNetworking, but this is used by the latest versions of the other both. Therefore the new resolver is now able to pick by backtracking versions in a way that it satisfies all dependency constraints or definitively state that this won't be possible at all.
