March 2026 Stable Update
Hello everyone! It is time for the March 2026 Stable Update, as well as some other news.
In regards to updating tModLoader to the Terraria 1.4.5 update: The Future Terraria 1.4.5 Support and Improving Security sections below are a repeat of last month. The tModLoader team is hard at work moving thousands of code changes over to the new Terraria source code. Once this initial process is completed, we will be ready to accept community contributions to further adjust the tModLoader API to changes made in 1.4.5 and any other big changes desired by the modding community.
We hope everyone has been having fun playing the new Terraria v1.4.5 update (Bigger and Boulder). If you didn't know, Terraria recently launched a huge update, be sure to check it out.
We know everyone is looking forward to tModLoader and mods having access to all of the new content and features as well. 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.
We will have more information to share in later months as we start working on the update and have a better idea of the work involved.
We encourage modders to take this opportunity to come discuss any tModLoader API shortcomings as well on Discord and Github. Major releases present an opportunity to fix issues that couldn't be addressed properly in regular monthly releases.
[h2]Terraria 1.4.5 Support FAQ [/h2]
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.
We also want discuss our recent efforts in combating malware distribution on the workshop. As some of you may be aware, in the past year there has been an increase in attempts to use tModLoader to distribute malicious code. As members and supporters of this incredible modding community, we want to assure both players and modders that we are taking steps to respond to this new wave of malicious mods. We have already improved the server mod-syncing feature to be significantly safer and introduced several backend systems for validation and moderation.
Recently, in partnership with Valve, we introduced a new approval queue to give us a chance to catch malicious mods and updates before they have a chance to make it to users. As this tooling is new for Steam Workshop, we greatly appreciate the patience of modders while we work through the kinks to reduce moderation times and user issues. We will continue to adapt and limit as many attack vectors as reasonably possible to protect our community, however there is always some inherent risk with using mods.
We encourage everyone to be vigilant and diligent as always and are thankful this community contains many members who actively seek out and help us identify new risks and mitigations. We'd like to thank Jamz for developing and testing code analysis software, and the many people who have analyzed suspicious mods and reported potential malware to us for investigation and action in the past.
Here is a collage of new mods released this past month. There were over 550 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.
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.
