 Additional file support for H.264 and MPEG-4 formats was also included, whereas the older Zune 30 requires these formats to be transcoded to WMV prior to sync.The ability to sync wirelessly (automatically if connected to a power supply), podcast support, and an upgraded song-sharing licensing became available on all models.The new software also allowed a Zune device to communicate with other Zune devices to share pictures and songs.
