I successfully migrated to version 5, so I guess that's good. However, I have my station blueprints set up with 8/13 chests restricted to 20 slots each, and the remaining 5 completely restricted. In version 4, the merged chest would inherit the total unrestricted count, having 160/624 available. Currently, the restrictions are removed when the chests are merged. The restriction is also lost when the chests are un-merged. I'm mostly merging steel chests, with occasional logistic chests as well. I don't think this is completely broken, I can remember to re-restrict chests. It is certainly annoying though.
