Build 3468 and 3474 introduced new features but also an unexpected bug. They were
removed from the released build download area while the bug gets resolved.
Users who loaded these builds should consider reverting to build 3390 for stability.
If you are running customized profiles that have been saved with a new name other
than the default sample names, you can reload build 3390 and your customized profiles
will still be here.
If you are still running with profiles named Mach4Mill, Mach4Mill_6Axis, Mach4Lathe,
or Mach4Router then you should use the Copy Profile function of Mach4Loader to
make a fresh copy of your profile with a new name before reloading build 3390 so
that your profile does not get overwritten.
