This wiki is primarily concerned with documenting the current state of the game, though admittedly we're lagging in places. This page is an exception, dealing with its history. It lists the release dates for major upgrades, with links to the official patch notes for those releases. This page is probably of little interest to players, but may be a useful resource for editors. It was created by an editor who found it useful to review the relevant patch notes introducing a new feature when trying to describe the current state of that feature, and who thus wanted a simple way to store the links to those pages.
