This is a placeholder for the new Alchitry Cu. It'll have the same features as the existing Cu but be in the new Alchitry V2 format (smaller board, new connectors).

Note that the Lattice FPGA requires a license for iCEcube2. This is free for hobbyists. Scroll to the bottom of this page for current details.
