6.3.0 - 2026-05-22

🧹 Refactor

• Remove the build hook that either downloaded prebuilt binaries or compiled
  native C wrappers for Win32 APIs that report errors via GetLastError().
  These bindings now pre-resolve GetLastError() before each call, ensuring the
  error code is captured reliably without any native code.

6.2.0 - 2026-05-07

🚀 Features

• Add OsVersion class for reliable Windows version detection and OS baseline
  checks. Use OsVersion.current to retrieve the running version and the
  relational operators (<, <=, >=, >) to range-check it against
  well-known baselines (OsVersion.win10, OsVersion.win11, etc.).

• Add extension methods on GUID for comparison and ordering: compareTo(),
  isEqualTo(), and the relational operators (<, <=, >=, >). Useful for
  using GUID as a key in sorted collections such as SplayTreeMap.

• Add GET_X_LPARAM() and GET_Y_LPARAM() macros for correctly extracting
  signed x/y cursor coordinates from Windows message parameters. Unlike
  LOWORD()/HIWORD(), these macros handle negative coordinates that occur
  when a secondary display is positioned to the left of or above the primary
  display.

🐛 Bug Fixes

• Fix IsWindowsServer() using the wrong constant.

6.1.0 - 2026-04-22

🚀 Features

• The build hook now downloads prebuilt binaries from GitHub release artifacts
  instead of compiling from C source, eliminating the MSVC requirement for
  users who don't have the necessary tools installed.

  Users who prefer or require local compilation can opt out by setting the
  local_build user-define to true in their pubspec.yaml:

  hooks:
    user_defines:
      win32:
        local_build: true

🔄 Breaking Changes

This release introduces a major redesign of the Win32 Dart API with a strong focus on type safety, deterministic resource management, and idiomatic Dart usage. Most changes are mechanical but widespread.

Key breaking changes include:

• Exception-based error handling

  • APIs returning HRESULT now throw WindowsException on failure
  • Logical return values are returned directly instead of via out-parameters

• New error model for APIs that call SetLastError()

  • Such APIs now return Win32Result<T> which captures both the logical return value and the associated last-error code atomically on the native side, ensuring the error state is preserved

• Strongly typed Win32 handles

  • Opaque handles (e.g., HKEY, HWND, HICON) are now extension types instead of plain int or Pointer values

• Win32 BOOL mapped to Dart bool

  • Applies uniformly to return values, parameters, and struct fields

• Enums are now extension types

  • Replaces raw int constants with strongly typed extension types

• Explicit COM lifetime management

  • Automatic cleanup via Finalizer has been removed
  • COM objects must be released explicitly or managed with Arena

• COM and HRESULT API simplifications

  • QueryInterface-style methods now return interfaces directly
  • Manual HRESULT checks and pointer plumbing are eliminated

• Major string API cleanup

  • Renamed and simplified string conversion helpers
  • Removed TEXT(), BSTR class, and legacy helpers

• GUID API redesign

  • Removed Guid class and string-based helpers
  • GUID struct is now the single, explicit representation

• winsock2 library removed

  • All Winsock APIs are now exported directly from win32.dart

• Dispatcher API redesign

  • Strongly typed results
  • No manual VARIANT or DISPPARAMS construction
  • Explicit ownership and cleanup

See the Migration Guide with examples and mechanical migration steps.

🚀 Features

• Scope-based lifetime management

  • New extensions for Arena to manage native memory and COM lifetimes

• Much stronger type safety across the API surface

  • Typed handles, enums, booleans, GUIDs, and COM interfaces

• More idiomatic Dart APIs

  • Fewer pointers, fewer out-parameters, clearer ownership rules

• Reliable error handling

  • Atomic capture of GetLastError() values on native side, exposed via Win32Result<T>

• Cleaner, more consistent conversion APIs

  • Unified naming and semantics for strings, binary data, and FILETIME values

• Native memory leak detection via package:ffi_leak_tracker

  • Tracks allocations with call stacks and timestamps; see the Leak Tracking guide for details

• [BREAKING CHANGE] Experimental WinRT APIs are now removed, in favor of the new windows_* packages (see https://win32.pub for more information) 🎉

• [BREAKING CHANGE] Finalizer is now attached to COM objects. Therefore, you no longer need to call .release() to decrement the reference count, because Finalizer will do it for you when they go out of scope (#691).

  Note: Calling .release() with Finalizer attached may result in use after free and cause the process to crash

  Note: If you're manually managing the lifetime of the object, you need to call .release() to decrement the reference count

• Add Windows metadata interfaces (IMetaData*)

• Fixed memory leak in convertToHString

• Upgrade to Dart 3 and add class modifiers to Struct subclasses

• Added detach method to IUnknown, which detaches the object from Finalizer if you want to manually manage the lifetime of the object yourself (#677)

• Revert upper Dart SDK constraint update due to pub analyzer bug.

• [BREAKING CHANGE] COM objects now inherit from NativeFinalizer. Instead of directly releasing the memory allocated for them, you can now call .release() to decrement the reference count, and the memory will be automatically disposed when the refcount falls to zero (#623, @halildurmus)
• Update examples for new COM release mechanism (#623, @halildurmus)
• Update to latest Win32 metadata (#626, @timsneath)

• Fixed memory leaks in COM and WinRT code when an exception is generated.
• Update to the latest Win32 metadata from Microsoft.
• [BREAKING CHANGE] The WinSock APIs now use upper cased naming for structs. For example, hostent is now HOSTENT. This will only affect you if you explicitly imported win32/winsock2.dart.
• [BREAKING CHANGE] TouchInputParameters is now upper-cased in the metadata.

• Improve projection of Map, Vector, and reference Windows Runtime types, with thanks as ever to Halil Durmus (@halildurmus).
• Add CryptoAPI functions (CryptProtectData, CryptProtectMemory etc.)
• Add pointer and touch APIs
• Fix WinRT FilePicker demo
• Add raw printer API example
• Remove console example console.dart (use https://pub.dev/packages/dart_console instead).

• This release includes an overhaul of the COM and WinRT API generation, as described below. Apps and packages that call traditional Win32 APIs should not require changes, but apps that use COM or the highly-experimental WinRT APIs should expect to make changes.
• [BREAKING CHANGE] WinRT APIs have been moved to a separate library. This provides isolation for apps that only use traditional APIs (Win32/COM) from the more experimental WinRT APIs. To use WinRT from your code, change your import statement to import 'package:win32/winrt.dart';. The WinRT library also exports all Win32 APIs, so you don't have to import both libraries.
• [BREAKING CHANGE] COM and Windows Runtime methods and properties are now camelCased, not TitleCased. This is inconvenient, but it avoids a whole class of name clashes and aligns COM and WinRT APIs more closely with Dart idioms. As the projections get smarter with more helpers, we think this is the right call for the future and worth a one-time tax to fix.
• [BREAKING CHANGE] You can now cast to a new COM interface without needing the IID for the target interface. Instead of:

  final modalWindow = IModalWindow(fileDialog.toInterface(IID_IModalWindow));

write:

  final modalWindow = IModalWindow.from(fileDialog);

• [BREAKING CHANGE] WinRT classes now support projection of Lists and Strings directly.
• [BREAKING CHANGE] The WinRT fromPointer method is now fromRawPointer.
• GUIDFromString now supports an optional custom allocator parameter.
• Added various APIs from iphlpapi.dll for tracking and renewing IP addresses.
• Added DisableThreadLibraryCalls, FindStringOrdinal, GetConsoleCP, GetConsoleOutputCP, GetModuleHandleExW, GetNumberOfConsoleInputEvents, GetVolumeInformation, GetVolumeInformationByHandle, PeekConsoleInput, ReadConsoleInputW, SetErrorMode, SetThreadErrorMode, SizeofResource APIs from kernel32.dll
• Added GetClassFile API from ole32.dll
• Added SetupDiGetDeviceInstanceId, SetupDiGetDeviceRegistryPropertyW APIs from setupapi.dll
• Added GetAltTabInfoW, GetClassNameW, GetGUIThreadInfo APIs from user32.dll

• Major reworking of the WinRT generation code, thanks to @halildurmus.

• [BREAKING CHANGE] Major work on Windows Runtime APIs, with huge thanks to Halil Durmus (@halildurmus). Breaking changes are limited to WinRT APIs, which are now more idiomatic for Dart. Includes full implementation of Windows.Globalization.Calendar that is the new reference design for WinRT APIs.
• Restructure generation code into a separate package.
