This is the third alpha of Lacewing Build #18. The previous builds have been tested privately.
Build #18 uses the new version of liblacewing, which is an entirely different library than what was used by earlier versions of the extension. It is incompatible with the previous protocol specification, and there's a public pylacewing server at ledev.org:6124. The old Lacewing server will be taken down as soon as this is released as a stable build.
Please report all bugs in this thread. Thanks for testing!
