Foreman 2.0.1 and Factorio 0.15:
This is one of the last updates where Foreman will be able to import blueprintstrings. Use the new vanilla blueprint Library (press B by default) to store your blueprints and create strings.
You can no longer export blueprints, only import them from the old BlueprintString/Foreman format. The new vanilla format will not be supported.
Foreman will (given time) turn into a blueprint manipulation tool.
