Ex2700 new firmware coming soon?

I'm trying to check to see if there is a firmware update beyond v1. 0.1.52

The automatic check on Netgear genie fails. Having checked the website, firmware version . 1.52 is showing under Previous Versions and there is nothing showing under current version. Maybe this is why the auto check is failing.

Is this an oversight or is a newer version imminent.

Thanks.
