Have just recently upgraded to 2.6.0 beta1, can’t recall which version of 2.5.0 I was on previously, and now the API call to lookup a group is returning null for is_group_owner, instead of true/false. I’ve been trying to find a commit in GitHub that might explain the change in behaviour, but haven’t been able to identify anything.
Is this a bug, or do 3rd party API libraries need to get updated to support a maybe boolean return type?
