+text: |
+  Metal is a low-level graphics API similar to Vulkan or D3D12, which are both supported by Godot but not available on macOS and iOS. Until now Godot used a library called MoltenVK to run Vulkan over Metal.
+
+  This direct implementation is more efficient and allows greater control over features and performance trade-offs in the future. Early results have shown that this backend is at least as fast as Vulkan and in many cases much faster on Apple hardware.
+
+  Note that Metal support is currently limited to Apple Silicon (ARM) devices.

+blockquote: "Blend into the shadows"
+text: |
+  Thanks to bicubic sampling (and new antialiasing for direct light samples) your low resolution static shadows will now look better than ever.
+
+  This method for reading from lightmaps smoothes out sharp edges, but requires a small run-time performance cost. You can disable it in the project settings if needed.
