When TNoodle-WCA-0.13.4 was released last week, we announced that TNoodle-WCA-0.13.3 would briefly remain an officially permitted version. Since a week has passed, TNoodle-WCA-0.13.3 is now officially retired, leaving TNoodle-WCA-0.13.4 as the only official scramble program.

Please see last week's TNoodle-WCA-0.13.4 announcement for details.

Please remember that official competitions must use a current version of the official scramble program. This is always available from:
