migration from qpid 0.15 to 0.26

[Pam]

Hello,
I was using qpid proton 0.15.The broker is updated and now my proton stopped to 
work. It cannot send messages to new broker.
Now with the hope of that it will work "automagically" again, I try to update 
qpid proton from 0.15 to 0.26.I see that there are huge changes. It is not 
compatible.
I was using proton::event_loop::inject to inject some work in proton connection 
loop.Now I see that event_loop is gone!
How could I do the same with the version 0.26 with a minimal pain?
Thank you.
