[[TOC]]

This is a collection of links to changelogs, revisions and tickets of the first part (500–1 BC) of [https://play0ad.com/game-info/project-overview/ 0 A.D.], sorted by its releases. Work on the second part (AD 1–500) has not been started yet. The collection is divided by the phases of the classic [https://en.wikipedia.org/wiki/Software_release_life_cycle software release life cycle].

The version number links to the respective release announcement with downloads, descriptions of major changes and an explanation of the codename. You can also click on the codename to find out more about its origin. The listed release date is the date of the official announcement. However, the actual release date can vary depending on OS (GNU/Linux, Windows and Mac OS) - see also the [http://releases.wildfiregames.com/ download archive]. Changelogs list and describe selected changes out of all code revisions. For Alpha 19 and older releases there are no changelogs available. If you are interested completing the information, please contact us on IRC. The related trac tickets are listed as well. Note, however, that development is mostly discussed on [https://code.wildfiregames.com/differential/query/OkjKx.5smavA/#R phabricator] and on [https://webchat.quakenet.org/?channels=0ad-dev IRC].

Further insights into the early project history can be found in [https://play0ad.com/about/the-story-of-0-a-d/ this article].
