CrossOver: Слой совместимости с Windows для Linux и macOS

Windows compatibility software

CrossOver is a Microsoft Windows compatibility layer available for Linux, macOS, and ChromeOS. This compatibility layer enables many Windows based applications to run on Linux operating systems, macOS, or ChromeOS. CrossOver is developed by CodeWeavers and based on Wine, an open source Windows compatibility layer. CodeWeavers modifies the Wine source code, applies compatibility patches, adds configuration tools that are more user friendly, automated installation scripts, and provides technical support. All changes made to the Wine source code are covered by the LGPL and publicly available. CodeWeavers maintains an online database listing how well various Windows applications perform under CrossOver.

CrossOver Linux is the original version of CrossOver. It aims to properly integrate with the GNOME and KDE desktop environments so that Windows applications will run seamlessly on Linux distributions. Before version 6, it was called CrossOver Mac Office. CrossOver Linux was originally offered in Standard and Professional editions. CrossOver Linux Standard was designed for a single user account on a machine. CrossOver Linux Professional provided enhanced deployment and management features for corporate users and multiple user accounts per machine. With the release of CrossOver Linux 11 in 2012, these different editions merged into a single CrossOver Linux product.

A standard copy of CrossOver now includes the functionality of CrossOver Games, CrossOver Standard, and CrossOver Professional editions. These older individual versions of Crossover have since been retired. CrossOver Games, announced on 10 March 2008, was a product intended to let users play a broad range of games by providing current Wine patches. The expectation was that it would update on a weekly to monthly schedule in order to incorporate the latest Wine programming work being accepted. In contrast the general CrossOver Office product focused more on stability and productivity software, and had a much slower beta and release schedule. CrossOver Games wasn't able to release updates with enough frequency to justify its separate production track and was discontinued in 2012. It was merged back into a unified CrossOver product. CrossOver Server was a specialized version of CrossOver Linux which allowed Windows applications to run on thin client systems. It was discontinued in 2007 as many of its features were present in the CrossOver Linux Pro edition.

On October 28, 2008 as the result of the Lame Duck Challenge, Codeweavers gave all of their products away for free. Codeweavers' main page was temporarily replaced due to the day's unusually high traffic. According to CodeWeavers at least 750,000 product registrations were given away during October 28. On October 31, 2012, CodeWeavers had a second software giveaway, this one entitled "Flock the Vote". CodeWeavers promised to have such a giveaway if 100,000 American voters would promise to vote on election day, in a nonpartisan bid to encourage activism. More than 100,000 people pledged, so CodeWeavers allowed any person in the world to download and register a copy of CrossOver Linux or CrossOver Mac.
