Excerpts from Doug Hellmann's message of 2018-04-27 10:02:08 -0400: > The latest release of reno tries to add anchors to the page in a way > that ensures they are named consistently across builds. For projects > with the same version number in multiple series (which can happen for > non-milestone projects that haven't tagged for rocky yet), this causes > duplicate anchors and causes the release notes build to fail. > > There is a fix for this in https://review.openstack.org/564763 and we > will try to get a new release of reno out as soon as that patch merges. > > Doug Reno 2.9.1 is available now and should fix this issue [1]. The constraint update is working its way through the gate [2]. [1] http://lists.openstack.org/pipermail/release-announce/2018-April/004988.html [2] https://review.openstack.org/#/c/564794/
