Hi Jan, do you think this bug will be resolved before the end of this sprint (September 4th)? If not, I'd like to set the "reviewed-in-sprint" flag.
Hi Dan, Eduardo created the Version bump including the fix for this BZ, so the new PR is https://github.com/openshift/node-feature-discovery/pull/52 I do not know if it will be merged this week or not. I would say set the flag to be safe.
The PR https://github.com/openshift/node-feature-discovery/pull/52 has been merged.
