CQ 5.4 to 5.6.1 - Features that encourage the upgrade?

Hi,

We are currently on CQ 5.4 and are thinking about the features in latest CQ(AEM to be precise) 5.6.1 that would encourage us to go for the upgrade. Can someone put some light on what features can be useful especially from a Server Operations / TechOps perspective that can lure us to go for an upgrade?

Meanwhile, Im reading through the release notes of all versions from 5.4 through 5.6.1 to understand the same. But any info that you can share, especially from a maintenance perspective can be really helpful.

Thanks
