Alexandre Julliard has put out his plans for the release of the next major version of Wine and it's going to be quite soon.
The next release, due around December 8th, will be the first Release Candidate for Wine 3.0. From there, they will be doing weekly RC releases and he estimates this will last 4-6 weeks. So the final Wine 3.0 release should be due in January if all goes well and no major release blockers are found.
Since the Wine 2.0.x release, there has been 22 development releases to make up Wine 3.0, with some pretty sweet new stuff to come for those sitting on the stable release. For most, none of it will be news, since they announce everything with each new development release.
Here's a quick rundown of what to expect from Wine 3.0 (since Wine 2.0.x that is):
- Multi-threaded command stream in Direct3D, which improves game performance.
- Support for tesselation shaders in Direct3D
- Shader improvements for Direct3D 11
- Improved DPI support
- More Shader Model 5 instructions
- Windows version set to Windows 7 for new prefixes
- Direct2D rendering improvements
- Lots of work towards Android support
- Lots more bug fixes and general improvements to existing features
