TypeScript 5.0 just released a few hours ago.

I would guess that tsup maintainers will need to test a bit to make sure nothing broke prior to updating their peer dependencies...

I've opened a PR to support the new syntax (the only change needed was to bump deps), which should allow tsup to accept TS 5.0

fixed in 6.7.0

TypeScript 5.0 seems to enforce the use of .d.mts and .d.cts for respective JS files.
Just wanted to mention #760 here, since it's probably going to get a lot more people finding it.

Hi there, our project is still failing with latest tsup and ts5:

packages/shared build$ tsup

packages/shared build: Failed

This is triggered with tsup > bundle-require > load-tsconfig.

Shall I open a new issue with it? The pr is here vuepress/core#1285

---

UPDATED: This is caused by load-tsconfig@0.2.4, rolling back to 0.2.3 is ok. @egoist This that package open source ? As I am not finding any repo information here

[egoist]

@Mister-Hope should be fixed in load-tsconfig 0.2.5

[Mister-Hope]

Thanks for the quick fix🎉, I also open a pr at load-tsconfig to add repo field.
