Hi there, We still get 9 deprecation warnings on /trunk. I don't think they are a release blocker but in the last couple of releases, we managed to resolve them.
For those API calls that simply added cancellation support, I would be fine with directly fixing them on 1.9.x (by setting cancellation parameters to NULL) and leaving them on /trunk as is. People may then bubble-up-revv the calling functions to support cancellation as well during 1.10 development. -- Stefan^2.
