tModLoader Patch Notes — June 1, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
Hello everyone! It is time for the June 2026 Stable Update, as well as some other news.
This month's announcement contains news about 1.4.5 update progress, a quick showcase of new mods from the past month, and the changelog for the new stable release.
Future Terraria 1.4.5 Support
As mentioned previously, the process of updating tModLoader to all of the new content and features of the Terraria 1.4.5 update (Bigger and Boulder) will take some time. This process as well as any other big changes desired by the modding community for this update will take many months still.
Terraria 1.4.5 Support Progress
Progress on the update this month has been very productive. We've seen many community contributions this month from experienced modders. We are extremely grateful for those willing to help with this process. The tModLoader team will continue to work with experienced modders to progress towards the tModLoader 1.4.5 update.
There are still many tasks to be done, if you are interested in contributing code for the 1.4.5 update, the 1.4.5 Update Information page has information on how to contribute and what tasks remain to be done. That page also explains how to join the "1.4.5-dev" beta branch. Users can join that beta branch to help identify and report remaining bugs, but please don't expect that version of the game to be stable.
We'd like to 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.

Terraria 1.4.5 Support FAQ
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.
