The changes merged together.
It sounds like one of the compute nodes is running older code.

Hope that helps,

So that means I need to check for another PPA nova build, when the changes will be merged in compute part?

I just took another look at those changes and they look correct.  It
appears that the version handling is working as expected and it's just a
compute node that hasn't been updated.
