Today, version 4.2 was released in the store.
For the most users, this update doesn`t bring any updates. But for those with the SYNC ADDON there are nice functions now:

• possibility to create a PDF to send as email or print.
  
• possibility to create backups of the entire calendar (all shifts) and to restore them, directly from OneDrive. This option will create a new folder on OneDrive with the name "Shift Scheduler" and every backup will be saved there with a new name (max. one backup each day). A backup will use only 10-50kB, so you will not loose space on your drive ;)
  

This will be the last release for Windows Phone 8.0. The next release will be available only for Windows Phone 8.1 (because I will implement some functionality that are only present on the new OS, like send emails with attachment).

In the last weeks many people reported that personal images are not visible on the Tile. This is something I never found out why. Hope with this version, it will work better.

For any questions, feel you free to ask it here :D
