ICANN just published it long awaited New gTLD String Similarity Contention Sets fand quite surprisingly just put four non-matching applications into two contention sets.
ICANN placed the new gTLD application for: .Hoteis by Despegar Online SRL into the same contention set as the application by Booking.com for .Hotels ICANN however, did not include the 7 applications for .Hotel into the contention set for .Hotels. source
