Scramble signatures should be used for all competitions (commit | discussion | discussion | discusssion) Scramble signatures are planned to become mandatory in 2020.

The WCA Delegate must not give scramblers (or anyone else) access to scramble sequences for any group before it has begun. (commit) Note that TNoodle 0.14.0 includes scramble set PDFs with individual passcodes to help with this.

Time limits have been clarified (commit) Time limits must be announced before the competition, rather than just before the round. Only one cumulative time limit can apply to a given round. Cumulative time limits include time elapsed in DNF attempts. The judge and WCA Delegate may estimate cumulative elapsed time (commit)

Scramblers should be visually isolated from competitors. (commit)

Many competition requirements have been moved from the Regulations to the new WCA Competition Requirements Policy (commit)
