To be clear: Vite, Vitest, tsdown, Rolldown, Oxc, Oxlint remain MIT.

Vite+ is a new product with a new license.

Glad to see TypeScript's Isolated Declarations feature already mentioned in three talks this morning at @viteconf.org 👍

It's one of the reasons tsdown and Oxc can generate Type Declarations so quickly ⚡

The main ID developer @titiancernicova.bsky.social is here if you wish to meet him.
Always happy to see something you worked on out in the wild! Love to see isolated declarations being used 😊. #viteconf.amsterdam

Just finished writing up an auto-fix for this in Oxlint, in case this was a blocker for anyone: github.com/oxc-project/...

Building performant tools doesn't happen by accident. They need a strong foundation!

@rolldown.rs and @vite.dev 8 are powered by Oxc for that reason

We've evaluated all previous PRs that went into the Oxidation compiler, 290 of them improving performance

This is what foundational work looks like!

Another beta - another bunch of improvements 🔥

Also includes changes from the latest Oxc version!
Rolldown v1.0.0-beta.39 has been released!

⚡ macOS Performance Boost: 10%-30% faster bundling, up to 45% in extreme cases.

🎯 Cross-Chunk Optimization: Support for __NO_SIDE_EFFECTS__ annotation, as well as
better tree-shaking across module boundaries and more efficient DCE
