The 2010 edition of the Open Water Worlds were the last stand-alone "open" (meaning no age limit) championships, and a Junior Open Water Worlds is to be created in its place. However, the Open Water events will remain in the biennial World Championships. This change brings the open water discipline closer to matching FINA's other disciplines in championships structuring.[3]
