FileMaker 14 Server had some quite useful changes when it was released.
Reconnect to server
If you lose your network connection or the server goes down, FileMaker Pro automatically reconnects to FileMaker Server when it’s available again — just like you can with FileMaker Go. Now FileMaker Pro puts you back to where you were in your solution before you were disconnected — so you can continue right where you left off.
Increase the security of FileMaker Server 14 with enhanced password controls. When creating passwords, the Admin Console will indicate the strength of your password — either weak or strong. Plus, set a hint to remember your password or re-set your password by entering a 4-digit pin number that you set up when installing FileMaker Server.
For experienced server administrators there is a new standby server option in FileMaker Server 14 to ensure higher availability of your business data. If your primary server ever goes down, type in a set of commands via the Command Line Interface to switch over to the standby server. Data on the standby server is also included in your scheduled backups.
