tModLoader August 2026 Stable Update Arrives as 1.4.5 Work Continues

The tModLoader team has published its August 2026 Stable Update, authored by javidpack. The announcement covers three areas: a changelog for the new stable release, a showcase of recent mods, and a progress report on the ongoing effort to support Terraria 1.4.5 ("Bigger and Boulder").

What changed

• A new stable release has shipped (specific changelog details were not included in the available source text).
• Work on tModLoader 1.4.5 compatibility is ongoing and expected to take many months still.
• A 1.4.5-dev beta branch is available for players and modders who want to report bugs ahead of the full release.
• Community contributions — code, bug reports, testing, and Discord discussions — are actively welcomed and credited as significant to progress.
• Modders are encouraged to raise API shortcomings with the team on Discord, as major releases offer a window to fix issues that regular monthly updates cannot address.

On mod compatibility, the team is direct: due to the scope of changes in Terraria 1.4.5, existing mods will not all work immediately when that update eventually arrives. Modders will need time to update their work.

For players, the stable update provides a clean release to use today, while those willing to accept rough edges can join the 1.4.5-dev branch and help shape what the next major version of tModLoader looks like.
