It aims for the improvement, but as it's Beta and the first public one - you shouldn't expect it to be stable or bug free. If you are using Mac OS 10.4.x - I recommend you stick to the 5160 until this new update becomes official release unless you need the "bleeding edge of technology"
But if something is totally broken for you with Leopard and 5160 - it's up to you to check if beta-testing will help you to solve these problems. But please keep in mind that beta-testing may prove to be dangerous for your data, so you shouldn't risk it unless you are really sure what you are doing.
