I will ommit this release and wait for 1.1.9.x with SFOS 2.0 UI but those who are interested can check it out (taken from XDA thread)

Changelog: Alpha13 - 10 September 2015

• Play classic Android OpenGL games from APK files (no apps only games)!

• Android's virtual SD Card is now mounted on bootup, so all photos, videos, music are now visible in Sailfish OS apps!

• MTP transfer mode works (not thoroughly tested), just choose "PC Connection" in Setting->System->USB

• Sailfish OS 1.1.7.28
