Exchange CU update compatibility

Hi all,

Any ideas when BE will be supporting the latest CU versions of Exchange?

CU19 was released for Exchange 2013 in December but neither 16 or 20 (I only found out about 20 last week) support it.

16 supports CU17, 20 supports CU18 for Exch. 2013

We have all SP's and hotfixes installed for v16 already by the way..

Can anyone shed any light on this?

Thanks
