I didn't see anything in the Changelog regarding this. The Pedia entry reads the same as before:
Even if it's not possible to open it to the Experimenter system, there were other closer systems.Generates a single new starlane to the nearest system that can be connected without crossing existing starlanes or passing too close to another system.
The Bore was created at Draco I. The intention was to open the starlane to Gari a Asteroids, instead it ended up connecting to an empty spot well off to the upper left.
