nRF52840 - changes of reference design

I'm currently working with an own hardware with a nRF52840. We had some time to get the radio working, because we copied the schematic of the PDK. In the reference design of the nRF52840 PDK, the connection between DEC4 and DEC6 (prev. DEC2) was missing.

I found the explanation of the problem here:

devzone.nordicsemi.com/.../

For the redesign of the hardware, I want to avoid mistakes like that. So I was wondering, if there are any other changes to the reference design. If so, is there a list of them? Or is there an updated reference design?

Thanks in advance!
