Patches and changes are always being applied to the Wine source code. There have been some attempts to track the status of Wine as more and more features are supported and tested.
Some information about current Wine progress can be automatically mined from the SourceCode, using scripts from the webtools repo and the tools/ directory of the wine repo. These statistics are regularly refreshed and should be up-to-date:
- Two slightly different reports of Wine's translation status can be found here and here.
- A quick summary of Wine test-suite results, with links to more detailed information.
Other Status Info
- A quick rundown of the features Wine currently offers, probably of more use to users or third-party developers.
