CMP Competition Rules for the 2021 competition season have now been approved by the CMP Rules Committee and are posted on the CMP website. The 2020 competition season was severely impacted by the Covid-19 pandemic and many 2020 events were cancelled, so the CMP still has a substantial inventory of printed 2020 rulebooks. In addition, the changes adopted for the 2020 competition season were not thoroughly tested, plus there was only a small number of changes for 2021. As a result, the CMP decided not to publish new rulebooks for 2021. 2020 Rulebooks will continue to be used and Errata sheets are being provided for each rulebook.
