The 10x is real for many projects, and the speed improvements make a huge difference for teams at scale. TypeScript 7 drops time in CI, and minimizes delays in editors like VS & VS Code. That makes every part of the developer inner loop feel snappy.

The new codebase has been battle-tested by many teams (and entire companies) using it in production for over a year now. In fact, in the editor TypeScript 7 is *more* stable than TypeScript 6, with fewer crashes and lower memory usage.

TypeScript 7 also ships a new `--watch` mode based on a Go port of Parcel's watcher. This brings more efficient and reliable file watching to TypeScript users across platforms.
If you tried earlier versions of TS7, you can expect way less CPU usage on idle with `--watch`.

Under both `--watch` and in the editor, TypeScript 7 also now periodically releases unused type-checking state after enough idle time. For bigger projects, this should help reduce memory usage after peaking.

TypeScript 7 also brings parallelism with new 🧪 experimental 🧪 flags to tweak it.
`--checkers` controls the number of type-checking workers, while `--builders` controls concurrent project builds.
Use more on powerful machines, or scale down to fewer to control memory usage.

We know people will still need TS 6 for API usage.
That's why there's a new `@typescript/typescript6` package that provides
- the TypeScript 6 API
- a separate `tsc6` binary
Install it side-by-side with TypeScript 7, and don't worry about conflicts with `tsc`.

@typescript Faster type checking makes every dev day slightly better. The build times alone would make me switch.
