MQX 4.2 USB_v2 stacks

I am trying to port my system from Kinetis-K60 to use K66 (I am using TWRK65F180M as a reference). In order to use this tower board, I've needed to upgrade to MQX4.2.

According to the MQX4.2 release notes, a new USB stack (v2) has been added for use with TWRK65F180M (I am using USB host).

My questions:

  1. Must I start using the USB_v2 stack with K66, or can I still use the legacy stack?
  2. If this is not a must - what are the advantages of doing so?
  3. How do I port the USB stack to USB_v2? Is there any porting guide available?
  4. Please notice that USB_v2 projects don't have any build files for cw10gcc as exist in all other projects (bsp, psp, mfs, rtcs, usb, etc....). is there any specific reason for that?
