April 2026 Stable Update NEW
Date: 2026-04-01 07:23:06
Hello everyone! It is time for the April 2026 Stable Update, as well as some other news.
This month's announcement contains news about 1.4.5 update progress, information about the new tModLoader-specific Workshop rules, a quick showcase of new mods from the past month, and the changelog for the new stable release.
We know everyone is looking forward to tModLoader and mods having access to all of the new content and features of the Terraria 1.4.5 update (Bigger and Boulder). We'd like to remind users that updating tModLoader to major Terraria releases is a huge undertaking. We are committed to working diligently on migrating to v1.4.5, but it does take some time, so we ask players to please be patient.
For context, the process of updating tModLoader to v1.4.4 took 9 months. During that process, many large features were added to tModLoader to better support the capabilities of mods, which did extend the porting process quite a bit. We don't expect quite as many large changes this time, so the actual porting process should be shorter than how it was for v1.4.4.
This process as well as any other big changes desired by the modding community for this update will take many months still. We ask that players and modders remain patient as we work on the update. tModLoader will continue to work as expected during this process, but please note that Terraria players and worlds played on the 1.4.5 update can not be migrated to and used on current tModLoader.
The tModLoader team spent this last month moving thousands of code changes over to the new Terraria source code. This initial porting process has mostly been completed and we can now compile and launch the development build of tModLoader once again. We are especially thankful to tomat for contributing a large amount of code to this process as well.
Now that this initial process is mostly complete, the code is in a state where we are ready for experienced contributors to help us go the rest of the way in restoring any remaining functionality. We'll need to verify that everything behaves as it did before, implement changes from the new Terraria update into our existing edits, and update the API in places where improvements need to be made.
We also encourage modders to take this opportunity to come discuss any tModLoader API shortcomings with the tModLoader team and contributors on Discord, even if they are not able to personally contribute the changes. Major releases present an opportunity to fix issues that couldn't be addressed properly in regular monthly releases.
As usual, community contributions are discussed mainly on Discord initially and then on GitHub to be implemented.
Q: "Will all of my mods still work on v1.4.5 immediately?"
A: Due to how much has changed in the Terraria v1.4.5 update, the short answer to this is "no". Modders will, however, have ample opportunity to update their mods to v1.4.5 before it is officially released, so as long as the mods you are using are still maintained by the modder, they should be available on v1.4.5 once it has a stable release for players.
Q: "What will happen to 1.4.4?"
A: 1.4.4 mods and the 1.4.4 version of tModLoader will continue to exist and be available for players both during porting and after. It will be supported as a Legacy version like 1.3 and 1.4.3.
Q: "When will 1.4.4 stop receiving updates?"
A: 1.4.4 will continue to receive maintenance updates to ensure it stays functional. We do not have a date for when content updates will stop; in the near-term 1.4.4 will continue to receive regular updates until we are ready to 'Preview' the 1.4.5 beta build to modders.
Q: "Will 1.4.5 be backwards compatible with my worlds and players from 1.4.4?"
A: From tModLoader's side, one of our guiding principles is to ensure the player experience is as seamless as possible. We aim to maintain backwards compatibility in tModLoader and encourage modders to keep this in mind when it comes time.
In our continued efforts to provide a safe environment for all players, we recently introduced a workshop rules agreement. Modders publishing to the Steam Workshop will be required to accept these rules the next time they publish an update or new mod. We encourage modders to review the rules and keep them in mind as they create mods.
As a reminder, there is now a moderation queue for mods to allow our moderation team to review the code of each mod. If your mod has not been approved in over a day feel free to reach out on Discord and we will look it over again.
We hope these new rules as well as our continued moderation will help keep players safe.
Here is a collage of new mods released this past month. There were over 450 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 will continue to update the 1.4.4 version of tModLoader with bug fixes as we work on updating tModLoader to the Terraria v1.4.5 update (Bigger and Boulder). We are grateful for the massive amount of community participation in developing and testing new features each 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.
