ChangeLog

The current release is 2.0.1 (September 2026). Source is the tarball next to that entry. There is no separate public Git repository.

the autorouter is new and no longer uses the maze search of the Java program; fanout, routing passes and the postroute optimizer are described under How the Autorouter Works,

--no-postroute skips the optimizer after --autoroute,
memory use of autoroute and the optimizer stays bounded for the whole run,
the mouse wheel zooms while autoroute or the optimizer is running,
the window translations (German, French, Spanish, Italian, Russian, Japanese, Chinese) use the board terms of the program,
