v0.18.0 — SubpixelLayout for LCD/ClearType Detection

Added

• SubpixelLayout on PlatformProvider (ADR-024) — SubpixelLayout() method returns display subpixel arrangement (SubpixelNone, SubpixelRGB, SubpixelBGR, SubpixelVRGB, SubpixelVBGR). Enables auto-detection of LCD/ClearType font rendering in gg. Follows Qt6 QPlatformScreen pattern — subpixel is a display/OS property, not GPU. NullPlatformProvider returns SubpixelNone.

Full Changelog: v0.17.0...v0.18.0

v0.17.0

What's Changed

Added

• AdapterInfo on DeviceProvider (ADR-020) — AdapterInfo() method returns AdapterInfo{Name, Type} with AdapterType enum (Discrete, Integrated, Software, Unknown). Enables gg render mode auto-selection: CPU rasterizer on software adapters vs GPU accelerator on real hardware.

Fixed

• Lint cleanup — extracted stringNone constant, 0 lint issues on all platforms.

v0.16.0 — Runtime Fullscreen Toggle Interface

WindowChrome: SetFullscreen + IsFullscreen

Added runtime fullscreen toggle to the WindowChrome interface (ADR-018).

Added

• SetFullscreen(bool) — enter/exit fullscreen mode
• IsFullscreen() bool — query fullscreen state
• NullWindowChrome no-op defaults

Enables App.SetFullscreen(bool) in gogpu for borderless fullscreen (Windows), native toggleFullScreen: (macOS), _NET_WM_STATE_FULLSCREEN (X11), xdg_toplevel.set_fullscreen (Wayland).

v0.15.0

Type-Safe GPU Resource Handles (ADR-018)

Breaking: TextureView changed from interface{} to opaque struct{ptr unsafe.Pointer}.

Changed

• TextureView — compile-time type safety via opaque handle (Vulkan/Ebitengine/Go Protobuf Opaque pattern). 8 bytes, value type, zero allocations, GC-safe.

Added

• CommandEncoder — opaque handle for shared encoder pipeline (ADR-017). Same pattern as TextureView.

Migration

// Before (v0.14.0)
var view gpucontext.TextureView = wgpuView // interface{} accepted anything

// After (v0.15.0)  
view := gpucontext.NewTextureView(unsafe.Pointer(wgpuView))
if view.IsNil() { ... }  // was: view == nil
ptr := view.Pointer()     // unsafe.Pointer for type assertion

v0.14.0

Added

• TextureView type token interface — type-safe render target for cross-package GPU operations. Follows Device/Queue/Surface pattern.

Full Changelog: v0.13.0...v0.14.0

v0.13.0

v0.13.0 — TextureRegionUpdater + gputypes v0.5.0

Added

• TextureRegionUpdater interface — UpdateRegion(x, y, w, h int, data []byte) error for partial texture upload. Enables incremental rendering where only dirty regions are uploaded to GPU instead of full texture.

Changed

• Dependencies: gputypes v0.2.0 → v0.5.0 (PrimitiveState zero value = WebGPU spec default)

Full Changelog: v0.12.0...v0.13.0

v0.12.0 — CursorMode + PointerEvent deltas

Added

• CursorMode — CursorModeNormal, CursorModeLocked, CursorModeConfined for mouse grab / pointer lock (SDL parity)
• PointerEvent.DeltaX/DeltaY — relative mouse movement in locked cursor mode

v0.11.0 — WindowChrome Interface

Added

• WindowChrome interface for custom window chrome (frameless windows)
  • SetFrameless / IsFrameless — enable/disable frameless mode
  • SetHitTestCallback(HitTestCallback) — custom hit testing for drag, resize, buttons
  • Minimize / Maximize / IsMaximized / Close — window controls
• HitTestResult enum (13 values): Client, Caption, Close, Maximize, Minimize, 8 resize edges/corners
• HitTestCallback type: func(x, y float64) HitTestResult
• NullWindowChrome — no-op implementation for testing

Enables replacing OS window chrome with GPU-rendered custom title bars. Implemented by gogpu.App (v0.25.0+).

v0.10.0 — Typed interfaces, remove HalProvider

Removed

• HalProvider interface deleted (HalDevice/HalQueue with any)

Changed

• Device, Queue, Adapter, Surface, Instance → minimal type-token interfaces
• Consumers type-assert to *wgpu.Device for full API (Go "accept interfaces, return structs")

v0.9.0

Added

• HalProvider interface for direct HAL device/queue access
  • HalDevice() any — returns underlying HAL device
  • HalQueue() any — returns underlying HAL queue
  • Optional interface on DeviceProvider — use type assertion
  • Enables GPU accelerators to share host devices without creating their own wgpu instance
