Hi Greg,

Why did you said that this issue is not fixed in OSP16?

The missing regex was introduced via a new version [1] so I think we can say that this is a bug fix and we don't need a work around but just to update oslo.utils on customers servers.

Thoughts?

Your proposed doc text look good to me.

Thanks,

Hervé
