Editing Wine (software) (section)

===Corporate sponsorship===
The main corporate sponsor of Wine is [[CodeWeavers]], which employs Julliard and many other Wine developers to work on Wine and on [[CrossOver (software)|CrossOver]], CodeWeavers' supported version of Wine. CrossOver includes some application-specific tweaks not considered suitable for the [[Upstream (software development)|upstream]] version, as well as some additional proprietary components.<ref>{{cite news

Canadian software developer [[Corel]] for a time assisted the project, chiefly by employing Julliard and others to work on it. Corel had an interest in porting [[WordPerfect#WordPerfect for Windows|WordPerfect Office]], its [[Productivity software#Office suite|office suite]], to Linux (especially [[Corel Linux]]). Corel later cancelled all Linux-related projects after Microsoft made major investments in Corel, stopping their Wine effort.<ref>{{cite news|last=Vaughan-Nichols|first=Steven J.|date=25 February 2002|title=That's All Folks: Corel Leaves Open Source Behind|publisher=Linux.com|url=https://www.linux.com/news/thats-all-folks-corel-leaves-open-source-behind/|access-date=11 May 2021|archive-date=12 May 2021|archive-url=https://web.archive.org/web/20210512134450/https://www.linux.com/news/thats-all-folks-corel-leaves-open-source-behind/|url-status=live}}</ref>

Other corporate sponsors include [[Google]], which hired CodeWeavers to fix Wine so [[Picasa]] ran well enough to be ported directly to Linux using the same binary as on Windows; Google later paid for improvements to Wine's support for [[Adobe Photoshop|Adobe Photoshop CS2]].<ref>{{cite web

[[Valve Corporation|Valve]] works with [[CodeWeavers]] to develop [[Proton (software)|Proton]], a Wine-based [[compatibility layer]] for [[Microsoft Windows]] games to run on [[Linux]]-based operating systems. Proton includes several patches that upstream Wine does not accept for various reasons, such as Linux-specific implementations of Win32 functions.
