A new version of the Regulations and Guidelines is going into effect January 1, 2014.
The scramble program will be updated soon to accommodate these changes, and the results will be updated with format changes.
The current Regulations are always available from https://www.worldcubeassociation.org/regulations/
For an exact list of changes from 2013 to 2014, view differences on GitHub.
For a summarized list of changes, please visit the full announcement.
The WCA Board has approved the addition of Skewb as an official WCA event, to take effect with the new Regulations on January 1, 2014.
See the announcement in the WCA forum for details.
The WRC is changing the official scrambling program from TNoodle 0.7.8 to TNoodle 0.7.12. This addresses two minor issues:
Please remember that official competitions must always use the current version of the official scramble program. This is always available from: https://www.worldcubeassociation.org/regulations/scrambles/

In response to feedback after the May 11 update to the Regulations, the WRC is updating the Regulations and Guidelines with the following changes. These changes are about puzzle defects at the end of an attempt:
This change is effective for all official competitions starting May 21, 2013.
Starting with the May 21 update, all significant updates to the WCA Regulations and/or Guidelines will be announced by the WRC in a post at www.worldcubeassociation.org/regulations/announcements
Such posts will also be made “sticky” on the main WCA homepage for a while, so that they are always at the top of the page.
The WRC will try to make sure such changes are only announced and put into effect at the beginning of the week (Monday-Wednesday), so that Delegates and competitors have time to learn of the changes (and respond with any urgent feedback).
Nevertheless, delegates and competitors are always encouraged to check the date listed on the current English Regulations before using a saved/printed version as reference for a competition.
On January 29, 2013 our fellow WCA member Raj Gala from India passed away due to Dengue fever. He was 18 years old.
Raj competed in 3 WCA competitions and was ranked #5 in India for Megaminx (single and average).
On the WCA Forum WCA delegate Gaurav Taneja and Raj's friends Yogesh and Bhargav write about Raj as a helpful and kind member of the Indian community.
Our thoughts and sympathy go out to Raj's family and friends.

The World Cube Association has released a new set of documents, effective January 1, 2013. All documents can be accessed via https://www.worldcubeassociation.org/regulations/.
The WCA Regulations go into effect immediately, and govern all official competitions sanctioned by the World Cube Association. The WCA Regulations are also supplemented by the WCA Guidelines. The Regulations should be considered a complete document, but the Guidelines contain additional clarifications and explanations.
The WCA has also added another scramble program to be used for official competitions; TNoodle can also be found at the link above.
Special thanks to:
- The WCA Board (Tyson Mao, Ron van Bruchem, Tim Reynolds, and Sébastien Auroux), Independent Advisory Committee (Anders Larsson), the WCA Delegates (too many to list) and members of the community for constructive feedback and review;
- Jeremy Fleischman, the point man and lead architect of the TNoodle Official WCA Scrambler project; and lastly,
- The entire WRC committee (Clément Gallet, Lucas Garron, Sébastien Auroux, Shelley Chang, and myself) for their their tireless efforts. Each of the members of the WRC spent an inordinate amount of time collecting data, reviewing Delegate and community feedback, and debating the merits of the WCA Regulations.
Happy New Year!
