It is time for the April Fools 2024 Stable Update.

The tModLoader team and our amazing community of contributors continues to improve tModLoader.

This month we've fixed several issues, the most impactful being the issue with corrupted config.json files preventing the game from loading for some users. We hope this fix allows users experiencing this issue to continue playing tModLoader.

Notably, the mod loading and syncing logic has been reworked in this month's release. Users will see a new menu when joining a multiplayer server if mods need to be reloaded, explaining which mods will be downloaded, enabled, or disabled.
The new menu can be seen in the image below.

As well, mod loading speed has been improved by roughly 10%. We expect to see faster mod loading times and more consistent syncing of mods in multiplayer.

We would like to encourage modders to read the new Assets wiki page[github.com] and apply the contained guidelines to their mods. We have noticed that many mods are incorrectly using the Asset system, leading to slow mod loading as a result.

As always, if you are having issues of any sort, definitely don't hesitate to check out our FAQ on GitHub [github.com] or reach out to us at our Discord[discord.com].

The following is a list of the most noteworthy changes made for this release. As a reminder, modders should consult the Update Migration Guide[github.com] to see how to adapt to the new changes after running tModPorter.
