Airbus has received the certification papers for its smallest wide body aircraft, the A330-800, on 13 February 2020both in Europe and the USA.
The A330neo's certification flight-test programme was successfully performed by a single aircraft, F-WTTO with c/n 1888. This started with the first flight in November 2018. Now the deliveries can start, to launch customer Kuwait Airways, which has eight on order. You are however not likely to see an A330-800 soon, because so far Airbus received orders for only fourteen aircraft from three customers.
