An updated version of the Applicant Guidebook was posted by ICANN with the opening of the new gTLD application window. ICANN states:
“The updated version incorporates clarifications made through responses previously published by the gTLD customer service centre. The main points of clarification are on topics such as batching, background screening, the applicant support program, Continued Operations Instrument, GAC advice processes, and the registry code of conduct. Additional information and answers to previously asked questions can be found in the Program's Supplemental Notes. These materials are not intended to introduce new requirements or criteria.”
The new version can be found here.
