Das Mono Team hat die Version 2.6 der Entwicklungs- und Laufzeitumgebung Mono und zugleich die Version 2.2 der IDE MonoDevelop veröffentlicht. Zu den Highlights in Mono 2.6 soll eigenen Angaben zufolge folgendes gehören:

• WCF client and server, the subset exposed by Silverlight 2.0.
• LLVM support, to improve performance on server/computational loads.
• Continuations/Co-routine framework Mono.Tasklets (background info)
• LINQ to SQL using DbLinq.
• New Soft Debugger, integrated with MonoDevelop on Unix and OSX (background).
• System.IO.Packaging.
• csharp shell now supports auto-completion (press tab to complete)
• xbuild can now build most msbuild projects.
• Mono debuts a verifier and security sandbox (used by Moonlight).
• More complete 3.5 API coverage.
• This release includes Microsoft's open sourced ASP.NET MVC, ASP.NET AJAX and Microsoft's Dynamic Language Runtime.

• MonoDevelop code is now LGPLv2 and MIT X11 licensed. We have removed all of the GPL code, allowing addins to use Apache, MS-PL code as well as allowing proprietary add-ins to be used with MonoDevelop (like RemObject's Oxygene).
• User interface improvements: the first thing that MonoDevelop users will notice is that we have upgraded the UI to fit modern ideas. We borrowed ideas from Chrome, Firefox, Visual Studio, Eclipse and XCode.
• ASP.NET MVC support, you can now develop, debug and build ASP.NET MVC applications from MonoDevelop.
• New T4 Macro processor (Text Template Transformation Toolkit) integrated directly into the IDE (Mono's T4 is also available as a reusable library for use and abuse in your own programs).
• Moonlight Project Support: you can now build, debug and run Moonlight applications using MonoDevelop.
• New MacOS and Windows support. Check our feature matrix for details.
