Today, Microsoft has published new Cumulative Updates:

• CU 8 – Microsoft Dynamics NAV 2016 (Build 46045)
• CU 20 – Microsoft Dynamics NAV 2015 (Build 46054)
• CU 32 – Microsoft Dynamics NAV 2013 R2 (Build 46057)
• CU 39 – Microsoft Dynamics NAV 2013 (Build 46056)

Generally, NAV 2016 has pretty more Platform Hotfixes than other three versions (they have only few of them). About Application Hotfixes, the last two version have most of all improvement.

Almost all Hotfixes, both Platform and Application are just improving some issues in system. If we wait something new, I think we will wait until new version will be published. In any case, I suggest to install the most recent cumulative update for your NAV version. And still better, upgrade your NAV to the freshest NAV version :). You will not make mistake.
