 - Avoid panicking in some interactions with invalid resources by @nical in (#3094)[https://github.com/gfx-rs/wgpu/pull/3094]
 - Remove `wgpu_types::Features::DEPTH24PLUS_STENCIL8`, making `wgpu::TextureFormat::Depth24PlusStencil8` available on all backends. By @Healthire in (#3151)[https://github.com/gfx-rs/wgpu/pull/3151]
 - Fix an integer overflow in `queue_write_texture` by @nical in (#3146)[https://github.com/gfx-rs/wgpu/pull/3146]
