OpenStack releases are numbered using a YYYY.N time-based scheme. For example, the first release of 2012 will have the 2012.1 version number. During the development cycle, the release is identified using a codename. Those codenames are ordered alphabetically: Austin was the first release, Bexar is the second, Cactus the third, etc.
These codenames are chosen by condorcet vote of the OpenStack Foundation membership. Codenames are cities or counties near where the corresponding OpenStack design summit took place. An exception (called the Waldon exception) is granted to elements of the state flag that sound especially cool. That exception was extended to other major landmarks and reference points.

Only single words with a maximum of 10 characters are good candidates for a name. Bonus points for sounding cool.
Prior to being put to a vote, name candidates will be listed on this wiki page. Community members are encouraged to raise concerns about any potentially highly controversial names at this time.
After the vote, the names are vetted for legal entanglements. The top-most result without issues will be chosen as the release name.
- The voting system changed over time:
- Prior to the J release, the popular vote was conducted using the basic Launchpad poll feature over the ~openstack group.
- For the J & K release, a public survey monkey poll was used
