Na een lange reeks van ontwikkelbuilds is er met versienummer 1.8 weer eens een stabiele uitgave van Wine verschenen. Wine is een opensource-implementatie van de Windows-api en maakt het mogelijk om DOS- en Windows-programma's op Linux, FreeBSD en Solaris te draaien. Een grote groep ontwikkelaars draagt bij aan Wine en er is voor gekozen om elke twee weken een nieuwe zogeheten ontwikkelversie uit te brengen in plaats van te wachten tot er een aantal nieuwe functies klaar is. Een a twee keer per jaar verschijnt er een stabiele uitgave. Hieronder is een overzicht te vinden van de belangrijkste verbeteringen sinds versie 1.7:
Text and fonts
- DirectWrite is implemented, and works for a number of applications. The implemented functionality includes:
- Font file loading from system or custom font collections.
- Building font families by combining similar font faces.
- Font matching algorithm using weight/width/slope model.
- Basic text layout support.
- Bi-directional level resolution and line breaks resolution.
- GDI interoperability API, including rendering to DIB section base target.
- Rendering to arbitrary target with generic rendering interface.
- Generating black&white and grayscale alpha bitmaps.
- Bold glyphs can be synthesized for outline fonts.
- Multiple replacements can be specified for a single font by using a multi-string entry under HKCU\Software\Wine\Fonts\Replacements.
- Vertical text uses the Unicode data tables for more accurate character ranges support.
- Character tables are based on version 8.0.0 of the Unicode Standard.
- The built-in Wingdings font contains more glyphs.
- Unicode bracketing pairs are supported in Uniscribe.
- The RichEdit control uses Uniscribe for more accurate text rendering.
- Hebrew and Arabic Mac OS code pages are supported. This improves support for loading translated font names from Mac OS font files.
- Direct2D is supported. Among the implemented features are:
- DXGI surface and WIC bitmap render targets.
- Geometries defined by straight lines and cubic Bézier curves.
- Drawing text.
- Solid color brushes and bitmap brushes.
- Opacity brushes.
- PNG files can be encoded in interlaced mode.
- Gamma information can be loaded from PNG files.
- Animated GIFs are correctly supported in GdiPlus.
- Direct3D 11 is supported, to about the same level as Direct3D 10.
- Simple applications using Direct3D 10 are supported. There are still many unimplemented features. Direct3D 10 requires support for at least OpenGL 3.2 and GLSL 1.50. Some of the changes and supported features include:
- Several resource update operations are implemented.
- Many more shader model 4 opcode are recognized.
- Constant buffers are supported.
- The various resource views are implemented.
- The various state objects are implemented.
- Stateblocks are implemented.
- A number of new DXGI 1.1 interfaces are implemented. This benefits Direct3D 10 and 11 applications.
- Direct3D applications correctly minimize and restore the display mode on focus loss.
- Fixed function vertex blending is implemented. This requires GLSL support.
- Per-vertex point sizes are supported. This requires GLSL support.
- The wined3d graphics card database recognizes more graphics cards. The graphics card detection code is simplified and improved. More reasonable fallbacks are picked for unrecognized graphics cards.
- On drivers that support it, GL_ARB_texture_mirror_clamp_to_edge or GL_EXT_texture_mirror_clamp are used to implement the "mirror once" texture addressing mode. Previously this required GL_ATI_texture_mirror_once.
- GL_ARB_depth_clamp is no longer required to correctly draw pre-transformed vertices with disabled z-buffering. This helps older graphics cards that can't correctly implement GL_ARB_depth_clamp.
- On drivers that support it, GL_ARB_blend_func_extended is used to implement the D3DBLEND_SRCALPHASAT blend factor.
- On drivers that support it, GL_ARB_sampler_objects is used to apply sampler states independently of the texture object they apply to. This helps applications that bind the same texture to multiple texture stages, but with different sampler states.
- On drivers that support it, GL_EXT_texture_snorm is used to support signed (normalized) texture formats. These are typically used for bump mapping. Previously these formats required either GL_NV_texture_shader, or fixups when loading and using them.
- On drivers that support is, GL_ARB_timer_query is used to support Direct3D 9 timestamp queries.
- Texture format restrictions are more strictly enforced. This allows applications to fall back to a different format instead of continuing with broken rendering.
- Direct3D 9 D3DTSS_CONSTANT texture stage constants are supported.
- Color keyed blits can be done by the graphics card. Previously these needed to be done by the CPU.
- NV12 surfaces are supported. This is used by some applications for playing back video.
- ATI1N textures and surfaces are supported, in addition to ATI2N textures and surfaces. This requires support for GL_ARB_texture_compression_rgtc from the OpenGL driver.
- When GLSL is supported, lighting for Direct3D 1-3 is more correct. However, for most application the difference will only be very slight.
- The IDirect3DSwapChain9Ex interface is supported.
- OpenGL core contexts, OpenGL ES contexts, and multi-threaded OpenGL command submission (known as "CSMT") have been added, however that work is not finished yet.
Audio and video
- SetCooperativeLevel() works better, affecting DirectDraw exclusive mode in particular.
- DirectDraw surface flipping is more correct. This affects applications that use more than 1 back buffer in particular.
- DirectDraw palette handling is better supported. This mostly affects older applications using 8-bpp display modes (but not exclusively.)
- "Client memory" surfaces are better supported, in particular related to the handling of pitch and texture compression.
- A Pulse Audio driver is implemented. It is selected automatically when Pulse Audio is running.
- 5.1 surround sound is supported in DirectSound. Stereo is the default, but other speaker configurations can be set through the Audio tab in Winecfg.

- The standard Open File dialog supports a drop-down menu for file manipulations.
- The 'My Documents' folder links to the XDG or Mac OS X 'Documents' folder if it exists.
- Many more shell Known Folders are supported.
- Scrollbar theming is implemented. Theming of other controls also works better.
- The Toolbar common control can save and restore its state.
- The 64-bit architecture is supported on Mac OS X; however, it's not 100% compatible with Win64, because of the OS X non-standard 64-bit ABI.
- Memory size is reported accurately on Mac OS X.
- Joysticks are supported at the WinMM level on Mac OS X.

- The 64-bit architecture is supported on Android.
- Binaries are built as PIE on Android, for compatibility with Android version 5.
New external dependencies
- Source files can be shared across DLLs, to allow building multiple versions of a DLL from the same source. This is more compatible than forwarding calls to a single master DLL. It's used mainly for the C/C++ runtime libraries.
- #pragma directives are supported in various source files to specify dependencies, for more accurate makefile generation.
- The IDL compiler supports WinRT namespaces.
- The message compiler uses mo files instead of po files for faster processing.
- Architecture-specific compile flags like -march= are supported in Winegcc and passed along to the assembler.

- libnetapi from Samba is used for configuring remote network shares.
- libpcap is used to implement the Packet Capture DLL.
- libpulse is used by the Pulse Audio driver.
- The OpenAL Soft library is used to implement XAudio2.
- The prelink tool is no longer necessary as long as the linker supports the -Ttext-segment option.
- Since the support for OpenGL core contexts in WineD3D is not complete enough yet, Direct3D 10 and 11 need to be supported in a legacy context / the compatibility profile, which means that they currently don't work on Mesa.
- Setting the PULSE_LATENCY_MSEC variable was sometimes necessary with the Alsa audio driver, but it can cause trouble with the Pulse driver. It is recommended to unset the variable.
