Hello everyone! It is time for the September 2026 Stable Update and other news.
This month's announcement contains 1.4.5 update progress, a quick showcase of new mods from the past month, and the changelog for the new stable release.
Terraria 1.4.5 Support Progress
If you are unaware, the 1.4.5.8 hotfix version of Terraria released a couple of weeks ago. In the release announcement, Re-Logic mentioned that this should be the last hotfix needed for the 1.4.5 (Bigger and Boulder) release. Adapting our current tModLoader update progress to the new hotfix should be straightforward and will happen in the coming weeks on the 1.4.5 beta branch.
We are still not ready to set a release date for when the 1.4.5 version of tModLoader will become the default release, but we wish to emphasize that it is being worked on constantly. We are continuing to see a huge amount of community participation and contributions for the 1.4.5 update and are extremely grateful for those willing to help with this process through code contributions, bug reporting, testing, and participation in the discussions that take place on Discord. This last month in particular has seen a surge in community contributions and bug reports.
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.
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.
