Developer Studio 3.1 has been released and is now available for download. If you’re already running Developer Studio 3.0, the update should be proposed the next time you’ll start it, or can be triggered with the Help \> Check for Updates menu. In order to install Developer Studio 3.1, please follow the [Getting Started](http://developer.sierrawireless.com/developerstudio) instructions. For more information on this release content, please read the [Release Note](http://developer.sierrawireless.com/Resources/Resources/AirPrime/Software/Release_notes/developer_studio_3_1.aspx) Please note that this version has been designed to be compatible with Legato 14.07, and will not be 100% compatible with previous versions features (device behavior, adef file format, etc…); it is recommended to use it only once you’ve migrated your environment to Legato 14.07 version. ---

Hi Isabel, Legato framework only runs on a Linux host due to the cross compilation tools required. However, you can run the Linux dev environment in a virtual machine in windows. I’ve been successful using vmware workstation to do this. Ciao, Dave ---

Yes indeed, Windows hosts are still not supported for Legato apps development and Target Management. But it’s in the roadmap for the next one; we’re currently working on it 😉 ---
