This preview of this major upgrade was announced weeks ago and now it is released. You can fetch the latest hardware design in the GitHub repository. Besides the long awaited support to WiFi, it also brought some minor improvements like the FEL button and ESD protection.
Test with rtl8189ftv:
The original firmware needs some modification to support using sdc2 as SDIO interface (mainly in the device tree) but now there are still some minor issues in my compiled firmware. I will update it as soon as the problem is solved.
