Some of those things you are looking at in the notes are a heads up to the Beta Testers so we know what to expect with the new version.  At one point the FBX was removed from the menu as part of the clean up of the menus.   If you look at the properties of the lights you will find an extra check box called Preview Light.  When you check this the light won't show in renders, but gives you light to work on the scene.  This helps to make easy to work and NOT forget to turn off the lights when it comes time to render.
