The API working group has three new guidelines that are entering the 1 week freeze period. We would like to ask all PTLs and CPLs, and other interested parties, to take a look at these reviews. We will use lazy consensus at the end of the freeze to merge them if there are no objections. Remember, these are guidelines, they are not meant to be taken as strict rules "from on high" that must be followed or else </ominous music>. For further information about the API working group and it's purpose, please see the group wiki[1]. The three guidelines up for review are: * Guidance on 500 internal server error, https://review.openstack.org/#/c/179365 * Clarification on state-conflicting requests, https://review.openstack.org/#/c/180094 * Clarification on when to use 409, https://review.openstack.org/#/c/179386 thanks, mike [1]: https://wiki.openstack.org/wiki/API_Working_Group#Purpose
