Sourced from wgpu's changelog.

Bug Fixes

• Fixed the build on docs.rs. By @​cwfitzgerald in #8292.

v27.0.0 (2025-10-01)

Major Changes

Deferred command buffer actions: map_buffer_on_submit and on_submitted_work_done

You may schedule buffer mapping and a submission-complete callback to run automatically after you submit, directly from encoders, command buffers, and passes.

// Record some GPU work so the submission isn't empty and touches `buffer`.
encoder.clear_buffer(&buffer, 0, None);
// Defer mapping until this encoder is submitted.
encoder.map_buffer_on_submit(&buffer, wgpu::MapMode::Read, 0..size, |result| { .. });
// Fires after the command buffer's work is finished.
encoder.on_submitted_work_done(|| { .. });
// Automatically calls map_async and on_submitted_work_done after this submission finishes.
queue.submit([encoder.finish()]);

Available on CommandEncoder, CommandBuffer, RenderPass, and ComputePass.

By @​cwfitzgerald in #8125.

Builtin Support for DXGI swapchains on top of of DirectComposition Visuals in DX12

By enabling DirectComposition support, the dx12 backend can now support transparent windows.

This creates a single IDCompositionVisual over the entire window that is used by the mfSurface. If a user wants to manage the composition tree themselves, they should create their own device and composition, and pass the relevant visual down into wgpu via SurfaceTargetUnsafe::CompositionVisual.

let instance = wgpu::Instance::new(&wgpu::InstanceDescriptor {
    backend_options: wgpu::BackendOptions {
        dx12: wgpu::Dx12BackendOptions {
            presentation_system: wgpu::Dx12SwapchainKind::DxgiFromVisual,
            ..
        },
        ..
    },
    ..
});

need an updated naga_oil first, then someone can adopt it

[jasmine-nominal]

naga_oil 0.20 has been released.

We also need a new release of dlss_wgpu, I will try and get to that tonight!

Closing in favor of #21746.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
