[NSMutableArray array]

returns an autoreleased array.

[[NSMutableArray alloc] init]

returns a retained array.

You don't own the autoreleased array, so you don't have to release it. You own the retained one (with alloc), so you have to release it.

[NSMutableArray array] is equivalent to [[[NSMutableArray alloc] init] autorelease].
