- AutoExec paths now support the same variable expansion as the search paths. Additionally, on Windows, the default autoexec path is now relative to $PROGDIR, rather than using a fixed path to the executable's current directory. - All usable Autoload and AutoExec sections are now created at the top of the config file along with some brief explanatory notes so they are readily visible to anyone who wants to edit them.
