Terraria’s next update is planned for January 21, 2019.
In a post on the game’s official website, the developer explained that this is “a lot to take in at once”.
It’s unclear when the next update will be released, but the next major update, version 1.7.1, was released on November 22, 2019, and is expected to be the final major update to the game.
It is likely that updates to Terraria will be rolling out at a more regular cadence, which means that the game will be out of date before the end of the year.
The next major patch is set to release in December 2019.
