Not necessarily, if you do not use SDK5 new API, that with four anyway.
If you need to use the new API, it is necessary to use SDK5, but also with LION.

Look what you will use API, if you want a compatible version 4, you do not try to API 5 and API documentation which each has a corresponding range of available

If you do not use the new features before you can, backward compatible version is definitely fixed with version 4.3 may be used to it
