Version 1.0.1 (04 Oct 2012)

• It's no longer possible by default to open a tunnel into the void. Added "void_tunelling" option to control this - defaults to false. Setting to true will allow tunnels to be opened into the void - take care!
• Bedrock by default now acts as a tunnel terminator - tunnel creation succeeds if bedrock is encountered, but bedrock at the end of the tunnel will not be removed. It's possible to tunnel through a single layer of bedrock by clicking it with the tunnelling book, but no more than a single layer (and never below Y=1 unless "void_tunnelling" is true).
• Maximum allowed tunnel distance is now configurable, independently for horizontal and vertical tunnels - see "max_tunnel_length.horizontal" and "max_tunnel_length.vertical" config settings. Both default to 31.
