What's new in Wine 8.0
======================

*** PE modules

- After 4 years of work, the PE conversion is finally complete: all modules 
can
  be built in PE format. This is an important milestone on the road to 
supporting
  various features such as copy protection, 32-bit applications on 64-bit 
hosts,
  Windows debuggers, x86 applications on ARM, etc.
  However, some modules still perform direct calls between the PE and the Unix
  part, instead of going through the NT system call interface. The remaining
  direct calls will be removed during the Wine 8.x development phase.

- A special syscall dispatcher is used for PE -> Unix transitions, to avoid 
the
  overhead of a full NT system call. This minimizes the performance impact of 
the
  new architecture, in particular for the OpenGL and Vulkan libraries.

- Building mixed Windows/Unix libraries in ELF format (.dll.so libraries) is
  still supported for use in Winelib applications. However, such applications
  won't support features enabled by the NT syscall interface, such as WoW64
  without 32-bit libraries.


*** WoW64

- WoW64 thunks are implemented for essentially all Unix libraries, enabling a
  32-bit PE module to call a 64-bit Unix library. Once the remaining direct
  PE/Unix calls have been removed, this will make it fully possible to run
  32-bit Windows applications without any 32-bit Unix library.

- When the 32-bit Wine loader isn't found, 32-bit applications are started in
  the new experimental "Windows-like" WoW64 mode (where 32-bit code runs 
inside
  a 64-bit host process). This mode can be enabled by building with the
  '--enable-archs' configure option. This is still under development and not 
yet
  recommended for general use. Since in case of configuration errors it is
  possible for it to be triggered inadvertently, applications started in this
  mode print the warning "starting in experimental wow64 mode".


*** Graphics

- The "Light" theme is enabled in the default configuration, for a more modern
  look. Other themes can still be configured through WineCfg.

- The graphics drivers (winex11.drv, winemac.drv, wineandroid.drv) are 
converted
  to run on the Unix side of the syscall boundary, and interface with the Unix
  side of the Win32u library.

- The Print Processor architecture is implemented. This will be used to avoid
  direct PE<->Unix calls in the printer driver.

- Effects are supported in Direct2D, including description parsing and a 
number
  of core objects.

- Command lists recording and playback are implemented in Direct2D.

- The Vulkan driver supports up to version 1.3.237 of the Vulkan spec.


*** Direct3D

- Many optimizations related to streaming map acceleration are implemented, in
  common code as well as in the GL renderer. Depending on the application, 
this
  may result in major performance improvements.

- Adapter video memory budget change notifications are implemented.

- The Vulkan renderer supports setting multiple viewports and scissor 
rectangles.

- Several Direct3D 10 and 11 features, which were already implemented, are
  accurately reported through capability flags:
  - Per-format support for vertex and index buffers.
  - Per-format support for all capabilities via D3D11_FEATURE_FORMAT_SUPPORT.
  - No-overwrite maps on shader resources and constant buffers.
  - Partial range binding of constant buffers.

- For convenience, a new WINE_D3D_CONFIG environment variable may be used 
instead
  of modifying the HKEY_CURRENT_USER\Software\Wine\Direct3D registry key. The
  value is a comma- or semicolon-separated list of key-value pairs, e.g.:

      WINE_D3D_CONFIG="renderer=vulkan;VideoPciVendorID=0xc0de"

  If an individual setting is specified in both the environment variable and 
the
  registry, the former takes precedence.

- The Direct3D graphics card database recognizes more graphics cards.

- The Vulkan renderer limits the maximum Direct3D feature level based on
  available Vulkan features.


*** Direct3D helper libraries

- A new HLSL compiler is implemented using the vkd3d-shader library.

- A new HLSL disassembler is implemented using the vkd3d-shader library.

- The HLSL preprocessor is reimplemented using the vkd3d-shader HLSL
  preprocessor.

- The D3DX 10 Thread Pump is implemented.

- Many more expressions are supported in Direct3D 10 effects.

- Cubemap projection is implemented in the D3DX 9 helper library.


*** Audio / Video

- The MPEG-1 audio decoder filter for layers 1 and 2, and the separate filter 
for
  layer 3, are both implemented on top of GStreamer.

- The ASF reader filter is implemented.

- The OpenAL32.dll wrapper library is removed, in favor of the native
  OpenAL32.dll library shipped by Windows applications.


*** Media Foundation

- Content type resolution is improved in the Media Foundation Player.

- Rate control is implemented.

- The Enhanced Video Renderer default mixer and presenter are better 
supported.

- The DirectShow filter is implemented in the Enhanced Video Renderer.

- An initial framework is implemented for the Writer encoding API.

- The topology loader is better supported.


*** Input devices

- Controller hotplug support is greatly improved, and controller removal and
  insertion are correctly dispatched to applications.

- Driving wheel device detection and reporting is better implemented, using 
the
  SDL library and HID usages as hints for the device types.

- Force feedback effect support is improved, specifically with driving wheel
  controllers.

- The HID Haptics specification is used for left / right motor rumble and 
trigger
  rumble. It makes it possible for device drivers to expose haptics support 
over
  HidRaw, and overcome EvDev limitations.

- The Joystick Control Panel is redesigned, with new graphics and a dedicated
  view for XInput gamepads.

- Sony DualShock and DualSense controllers are supported when the hidraw 
backend
  is used, and exposed to applications in the same way as they are on Windows.

- The Windows.Gaming.Input module is introduced, one of the first WinRT 
modules
  in Wine, implementing a new programming interface to access gamepads, 
joysticks
  and driving wheel devices.  For this new input API, hotplug notifications 
are
  also implemented, as well as force feedback effects and haptics. This API is
  the first one to support trigger rumble.


*** Internationalization

- A proper locale database, in Windows locale.nls format, is generated from 
the
  Unicode CLDR database. The list of supported locales is essentially 
identical
  to that of the latest Windows version.

- Unicode string comparison is based on the Windows Sortkey database and
  algorithms instead of the Unicode Collation Algorithm, yielding more 
compatible
  results.

- Characters from high Unicode planes (in UTF-16 encoding) are supported in 
most
  functions, in particular for case mappings, BiDi formatting, and character
  shaping.

- The UTF-8 encoding is supported as Ansi codepage. It is enabled when 
requested
  by the application's manifest.

- Unicode character tables are based on version 15.0.0 of the Unicode 
Standard.

- The timezone data is generated from the IANA timezone database version 
2022g.


*** Text and fonts

- Font linking is enabled for most system fonts, which should fix missing 
glyphs
  in CJK locales.

- Font fallback in DirectWrite is reworked, with additional support for an 
large
  number of scripts.


*** Kernel

- The ApiSetSchema database is implemented, replacing all the api-ms-* 
forwarding
  modules. This reduces both disk space and address space usage.

- DOS file attributes are persistent, and stored on disk using the 
filesystem's
  extended attributes, in a format compatible with Samba.


*** Internet and networking

- The Online Certificate Status Protocol (OCSP) is implemented.

- More EcmaScript features are supported in JScript standard-compliant mode.

- The JScript garbage collector is implemented.

- Accessibility support is enabled in Wine Gecko package.

- Web Storage, Performance object and more event objects are implemented in
  MSHTML.


*** Mono / .NET

- The Mono engine is updated to version 7.4.0. The list of changes can be 
viewed
  at https://github.com/madewokherd/wine-mono/releases/tag/wine-mono-7.4.0


*** Builtin applications

- All the builtin applications use Common Controls version 6, which enables
  theming and high-DPI rendering by default.

- The Wine Debugger (winedbg) prints thread names in the 'info thread' 
listing,
  for applications that set the names of their threads. All internal Wine 
threads
  also set their own name.

- The QWORD type is supported in the REGEDIT and REG registry tools.

- Notepad has a status bar displaying the current cursor position. The Goto 
Line
  functionality is also implemented.

- The builtin console programs print data in the OEM codepage, for better
  compatibility with applications reading their output.

- The Service Control tool (sc.exe) supports the 'query' command.


*** Development tools

- The PE conversion has made it necessary to implement a new mechanism to run
  static C++ constructors in Winelib ELF applications. Unfortunately, this
  requires the corresponding modules to be rebuilt with Wine 8.0.  The rebuilt
  modules will still run correctly on older Wine versions, but older modules 
will
  no longer execute static constructors when run on Wine 8.0.

- In regression tests, individual checks can be marked as "flaky". This is 
useful
  for checks that depend on external factors such as network timings. The 
errors
  are still reported but not counted as failures.

- Test failure messages can be printed in color by setting the WINETEST_COLOR
  environment variable, to make them easier to spot in the test log.

- The Resource Compiler (WRC) and Message Compiler (WMC) use the locale.nls
  database to detect languages and codepages, and thus support all the Windows
  locales.

- The WineDump tool supports printing the contents of Enhanced Metafile spool
  files, as well as more contents from PDB files.


*** Build infrastructure

- PE binaries can be built for multiple architectures from the same build 
tree,
  using the '--enable-archs' option to configure, for example
  '--enable-archs=i386,x86_64'. This can be used to enable the experimental
  WoW64 mode, where 32-bit applications can run without any 32-bit host
  libraries. Note that this mode is still under development and not yet
  recommended for general use.

- Data types that are defined as 'long' on Windows are defined as 'long' 
instead
  of 'int' on all platforms with a 32-bit long type. This is more compatible, 
but
  it can cause printf format warnings with Unix compilers. In Winelib code, it
  can be disabled by defining WINE_NO_LONG_TYPES.

- Import libraries can be generated without using dlltool, by passing the
  '--without-dlltool' option to winebuild. This is used to avoid dlltool bugs
  with delay import libraries.

- Libraries that contain only resources and no code can be built with the
  '--data-only' option to winegcc, which makes them smaller and more 
efficient to
  load.
