Changelog

Sourced from wgpu's changelog.

v27.0.1 (2025-10-02)

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,
            ..
        },
        ..
    },
    ..
});
