NBU command changes in 7.6

Hi, we are planning to upgrade the NBU for a customer. Currently all the master and media servers are NBU 7.5.0.6 on Windows Server 2008 R2. We plan to upgrade these servers to NBU 7.6.0.3. Currently the customers are using some customized scripts to eject tapes. We want to make sure the scripts are still working fine after the upgrade. So my question is:

Are there any changes of commands in NBU 7.6? Thanks in advance.
