The router began as a port of FreeRouting and has grown its own engine (negotiated congestion, tree nets, exact checks, axis escapes), and 'freeroute' was one letter from the project it no longer follows. The package, module and command are now rpmroute; the freeroute command stays as an alias, and the RPMROUTE / RPMROUTE_ORACLE_JAVA variables fall back to the old FREEROUTE names. Version 2026.10.07. Routing is unchanged: a PCBench board routes to a byte-identical session either way.
