What is Wine Staging?

Warning: Do not report bugs at bugs.winehq.org when using this version! Please take a look here for more information about how to report bugs.

Wine Staging (formerly wine-compholio) is a special wine version containing bug fixes and features, which are not yet available in regular wine versions. The idea of Wine Staging is to provide new features faster to end users and to give developers the possibility to discuss and improve their patches before they are sent upstream. We also intend to create a community of wine developers to share experience and to make it easier for beginners to start hacking on wine. More information about Wine Staging can also be found on our website wine-staging.com.

Although we are reviewing and testing all patches before adding them, you may encounter additional bugs, which are not present in vanilla wine. Make sure to report such issues in our bug tracker instead of winehq.org so that we can try to solve them in future versions. Thanks!

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.
