Hi,
On Thursday, January 18, 2018, we will merge the feature/zuulv3 branches of both Zuul and Nodepool into master.
If you continuously deploy Zuul or Nodepool from master, you should make sure you are prepared for this.
The current version of the single_node_ci pattern in puppet-openstackci should, by default, install the latest released versions of Zuul and Nodepool. However, if you are running Zuul continuously deployed from a version of puppet-openstackci which is not continuously deployed, or using some other method, you may find that your system has automatically been upgraded if you have not taken action before the branch is merged.
Regardless of how you deploy Zuul, if you find that your system has been upgraded, simply re-install the most current releases of Zuul and Nodepool, either from PyPI or from a git tag. They are:
Nodepool: 0.5.0 Zuul: 2.6.0
Note that the final version of Zuul v3 has not been released yet. We hope to do so soon, but until we do, our recommendation is to continue using the current releases.
Thanks,
Jim
