Why Doesn’t The Gulfstream G280 Utilize The Famous Gulfstream Ovular Windows?

The Gulfstream G280 is a super-midsize twin-engine business jet. It was first designed in 2005 as a follow-on aircraft from the G200. It first flew on December 11, 2009, and was launched in 2008. It is still in production today and over 200 Gulfstream G280 have been delivered since 2012. Gulfstream is well-known for its oval signature window design, so why did this aircraft not have them?
