New - Block Mappings!

Block mappings allow you to turn one block into another. Blocks which match the input will be turned into the output, states which are not set will also be converted where possible.

You can find Block Mappings under Advanced, after picking an export target. Block Mappings is currently in beta - whilst it has been tested exhaustively by our team, we're awaiting partner feedback and reports before it will leave beta.
