The Moto X4 started receiving Android 8.1 Oreo in May, and brought with it a couple of problems. Two months later, Motorola released the kernel source for that update, as required by the GPL each time there are modifications to the Android kernel.

What this means is that now the developers will have much easier to make custom ROMs and recoveries for the Moto X4 in Android 8.1 Oreo. So, if you own Moto X4 and want some software modifications for your phone, you should not wait much longer for some things to get to the forums.
