- WTA Tournament of Champions was held from 2009 to 2014, when WTA Elite Trophy replaced it.
- The first Premier 5 event of the year has switched back and forth between the Dubai Tennis Championships and the Qatar Open since 2009. Dubai was classified as a Premier 5 event from 2009–2011 before being succeeded by Doha for the 2012–2014 period. In 2015, Dubai regained its Premier 5 status while Doha was demoted to Premier status. The two tournaments have since alternated status every year.
