I just looked (Ver. 2) and I have DB version 2014.8.16.8 - same as you.
I clicked "Update Now" and it showed "No Updates Available".
To me it seems like MBAM hasn't released new V2 DB definitions "As expected" causing your warning.
I haven't found an issue reported on the MBAM forum, but it's early on a weekend, Sunday morning...
I won't be surprised if I get this warning later if MBAM doesn't push out new definitions !
Maybe the "MBAM DB updaters" are sleeping, or maybe a problem with the MBAM DB servers, or ....
Thanks for the heads up, as I may get calls later today if there is no V2 DB update !!!!
