Basically the function formerly known as do_main() in main.go has been renamed launch() and moved into launch.go. Now there are main.go and main_unix.go files implementing minmial main() functions which load a config and pass it to launch. This allows separating unix-specific security stuff (both the actual system calls which won't compile on other platforms and the definition of command line switches) out from the platform agnostic implementation of the main server logic. It also simplifies the interaction of relative paths in config files with chrooting. Docs still need updating...
