Male airport is gradually being developed with a new terminal underway with new parking apron south of the existing which I believe is no longer used.
A new runway has also been built but is not yet ready for use due nearby buildings etc still to be removed. Once the new runway opens the existing runway is to become a taxiway which will vastly improve capacity and reduce runway delays. The latest Google Earth image is worth a look.
I think now the only non-stop flights to Maldives from UK (COVID permitting) are from LHR with BA using B777-200/300s and Sri-Lankan with A330's.
