Upgrading from 1.7.0 — take the new Massive shape.

• Delete Massive.shape if you did not edit it, and restart. The startup log names it.
• Then run /wormhole gate regen <gate> on each Massive gate: its name sign stood inside the ring, and regen puts the block back and hangs the sign on the front. A gate with a hole where the sign was needs /wormhole gate regen <gate> -shape Massive -fill.
• Coming from 1.6.0? 1.7.0's steps apply as well: command keywords now need a dash, and the bundled shapes you have not edited should be deleted so the new dialling appears.
• Installing for the first time? None of the above applies. Drop the jar in and start.

Stargates

• Massive is the same on both sides, and its name sign hangs on the front of the gate.
• gate regen -fill places the few frame blocks a gate is missing, from its own materials.
• A build preview placed over a gate fills in what it is missing, then regenerates it.
• Taking a name sign down no longer leaves a hole in the frame.
• gate shapes validate catches a name sign that would land inside the gate.

Server

• /version WormholeXTreme says when the jar was built.
