Key improvements include parallelized parsing, type-checking, and emit; a more stable language server with richer editor features; and improved watch mode built on Parcel's file-watcher. One notable limitation: no programmatic API yet, meaning frameworks like MDX, Svelte, Vue, and Astro remain on TypeScript 6. The newsletter also briefly covers Bun's Rust migration blog post, a Node.js phantom dependency fix, new AI model releases (Grok 4.5, GPT 5.6), and a JavaScript beginner bug around dot vs. bracket notation for dynamic object keys. ## Full article daily.dev links to this article rather than hosting it.
