BA and Mauritius Airport - Anyone experienced the new Terminal?

I'm looking at going to Mauritius later in the year and despite searching the web, including here, I could only find one small review on Skytrax.

Has anyone been through the new Terminal since it opened late last year?

Is there Fast Track?

What is the new ATOL Lounge like?

Is the Arrivals lounge any good?

Airports of Mauritius operates two lounges, namely La Terrasse for departures and the Arrival Premium Lounge, in the airport terminal building. After long and tiresome journeys passengers can enjoy the calmness and beauty of these spaces, which are a perfect blend of exoticism and modernity, dedicated to their comfort. Along with special services provided to lounge users, trLavelling through the SSR International Airport becomes a hassle free and pleasant experience.

I've been to MRU three times before and only know the old set up so any info would be appreciated.

Thanks.
