Mixxx 2.5.1 Release Announcement

We're proud to announce a new stable release of Mixxx, version 2.5.1. It is recommended that all users update to this new version. Thanks to your feedback, this release contains a lot of improvements, fixes, new and improved controller-mappings. We would like to emphasize the importance of testing new versions. You don't have to be a programmer to contribute to Mixxx. Translating, testing new features and checking for possible regression is just as important.
