December 2025 Stable Update
Hello everyone! It is time for the December 2025 Stable Update.
But first, here is a collage of new mods released this past month. There were over 300 new mods this month! Have you tried any of these mods yet? Find any hidden gems? Be sure to regularly check the workshop for newly released mods, we're positive you'll always find something fun and interesting to try out. Click here to see the most popular new mods from this month.
We are grateful for the massive amount of community participation in developing and testing new features each month.
This month's release contains various bug fixes and smaller features. We've fixed several regressions related to the liquid rendering fixes from last month and fixed some UI inconsistencies and errors. For modders, this month's release includes support for custom pressure plates along with new hooks for tile interactions, as well as new hooks for custom armor set shadow effects and transforming the full player rendering.
Modders: As usual, we'd like to encourage modders to test out new tModLoader features on the preview branch if they are relevant to your mod. Major features in preview are announced in the preview-update-log channel on our Discord. We encourage mod makers to experiment with these and other new features on the preview branch and provide feedback this month so that they are ready for the stable release next month.
If you are having issues of any sort, definitely don't hesitate to check out our FAQ on GitHub or reach out to us at our Discord.
The following is a list of the most noteworthy changes made for this release. As a reminder, modders should consult the Update Migration Guide to see how to adapt to the new changes.
