[NSArray new] := [[NSArray alloc]init]

[NSArray array] := [[[NSArray alloc]init]autorelease]

+array and friends came along with the introduction of autorelease pools, to
replace +new with something that didn't imply ownership (the oft mentioned
special meaning of "new" as prefix). So while with ARC they are essentially
equivalent, previously they were not.
