BeagleBone White and BeagleBone Black - selecting right and latest hardware

Hello Beagle Fans - I want to order a Beagle Bone white and Beagle Bone Black board with LCD cape from Farnell/Digikey/Mouser and want to be sure that I order
latest hardware and matching LCD capes … - can anyone provide me with a pointer to a table / wiki page where I can retrieve such info ?

Thank you !
Michel
