What is Wine Staging?

Wine Staging is the testing area of winehq.org. It contains bug fixes and features, which have not been integrated into the development branch yet. The idea of Wine Staging is to provide experimental features faster to end users and to give developers the possibility to discuss and improve their patches before they are integrated into the main branch. More information about Wine Staging can also be found on our website wine-staging.com.

Although we are reviewing and testing all patches carefully before adding them, you may encounter additional bugs, which are not present in the development branch. Do not hesitate to report such issues at winehq.org, so they can be fixed before the feature gets integrated.

How to install and use Wine Staging

Ready-to-use packages for Wine Staging are available for a variety of different Linux distributions directly for download. Just follow the instructions available on the Wiki.

When using Wine Staging there are a few differences compared to regular Wine. The main difference is that it is not sufficient to type wine to run it, but instead you will have to type /opt/wine-staging/bin/wine. Besides that there are also some other differences, for example additional configuration options to tweak performance, which are not available in regular Wine. All those differences are also documented on the Wiki.
