I have had requests for mongodb 2.2.0 for Fedora 17, as well as EPEL 6
and 5.  I am going to build for those tomorrow and let things sit in
testing for at least a week (2 weeks for EPEL).

The only concern I have received thus far is whether packages will need
to be rebuilt against the new mongodb 2.2.

From everything I have looked at, the answer is no.
The API's should be backward compatible.
The libraries provided are the same name, there is no increase in number.

$ rpm -qp --provides libmongodb-2.0.7-2.fc18.x86_64.rpm
libmongoclient.so()(64bit)
libmongodb = 2.0.7-2.fc18
libmongodb(x86-64) = 2.0.7-2.fc18

$ rpm -qp --provides libmongodb-2.2.0-6.fc18.x86_64.rpm
libmongoclient.so()(64bit)
libmongodb = 2.2.0-6.fc18
libmongodb(x86-64) = 2.2.0-6.fc18

Thank You
