[hrydgard]

I'm sure there are plenty of good changes missing here, remind me please :)

Plus I should add some pull request references.

Thanks Unknown! I'll sort them a little bit and include most.

@hrydgard possible release of v1.8.0 in buildbot or ppsspp.org is March 12 😅

[hrydgard]

Is that a question? Yeah that's the plan, I'm not gonna be able to work much on it the upcoming week so just getting everything ready.

[Narugakuruga]

@hrydgard Do you recommend stick with D3D11 instead of Vulkan for Nvidia users? I wonder which are better...

[ghost]

@hrydgard thanks for answering :3

[hrydgard]

@Narugakuruga I'd recommend Vulkan since that's where the most future improvements are going to be. But if D3D11 works better for you, well, go for that.

[Narugakuruga]

Ok, I will wait till vulkan vsync be fixed.

People are noticing that https://www.ppsspp.org/version.json hasn't been updated.
