October 2026 Stable Update

Hello everyone! It is time for the October 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

Progress on tModLoader's 1.4.5 development branch is going smoothly. As mentioned last month, there was a Terraria 1.4.5.8 hotfix released that needed to be integrated into our 1.4.5 development branch. We are happy to say that those changes have been integrated this month and the development build now contains all the new changes.

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.

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.
