AMD released Radeon Software 19.2.3 today. Driver updates happen all the time, but the big news here is that it's the first unified driver to support their laptop GPUs as well as their desktop ones. AMD is still officially recommending that you use drivers provided by the laptop manufacturer rather than the ones direct from AMD. This is really only a backup plan for laptops from vendors who don't keep their drivers up to date--which is to say, all of them.
It's more than a little pathetic that it took AMD until 2019 to release official driver support for products that launched in 2017. Nvidia fanboys claiming that AMD's drivers are garbage are usually just being stupid, but they genuinely do have a rather spotty record on their laptop driver support, and this situation is hardly the first problem there. Still, it's better late than never, and for quite some time, it was looking like the arrival of official driver support genuinely would come sometime around never.
Driver support is only offered for Windows 10, not other operating systems. Still, that's an improvement over the previous situation of drivers not being available for anything at all.
