1.31 Point release introduces new way to play the game, plenty of major changes or plain removals of "DLC" content.

Today’s update marks a new chapter for Quake Champions as we transition the game from a free-to-play service to a paid application on Steam. Along with 30 Seasons worth of content to enjoy, all Champions are now unlocked for everyone, and most vanity content is available to equip. Battle Passes and microtransactions have been removed. Quake Champions is now available for one low price on Steam. No additional content updates are planned at this time. If you previously played Quake Champions on Steam, the new version will appear in your Steam Library at no additional cost.
