> Porting across r-code versions sometimes requires recompiling. The r-code version always changes between major releases. It may or may not change between minor point releases depending on the added functionality.

> If you port to:

> - A lower or higher major release, you must recompile.

> - A higher point release within a major release, you might or might not need to recompile, depending on the new functionality in the point release.

> - A lower point release within a major release, you might or might not need to recompile. However, it is highly recommended that you recompile.
