There seems to be no US version prior to V3, but there are CN, AU, EU, and UK previous versions.

All seems to sport the same CPU and Wi-Fi chipsets. To the knowledge:

• TP-LINK TL-WPA4220 - V1.0 seems to be CN and EU only.

• TP-LINK TL-WPA4220 - V1.2 is (was?) commonly available in UK and AU.

8 Mbytes RAM ESMT M12L64164A-5T (ANY1P4C4C). Different PCB layout.

• TP-LINK TL-WPA4220 v2 - V2.0 is EU & UK update, with again different PCB layout,
