[pnpm 11.0 Released](https://pnpm.io/blog/releases/11.0) — You’ve heard about [its benefits](https://pnpm.io/motivation), but now the popular package management tool is even better. v11 sets `minimumReleaseAge` to one day by default, there's an SQLite-backed store index (faster installs!), native package publishing, [`pack-app`](https://pnpm.io/11.x/cli/pack-app), and more. There's [a migration guide for v10 users](https://pnpm.io/11.x/migration). Work has also resumed on [a Rust-powered port](https://github.com/pnpm/pacquet) called _Pacquet_.

[TypeScript 7.0 Beta: 10x Faster TypeScript Compilation](https://devblogs.microsoft.com/typescript/announcing-typescript-7-0-beta/) — The Go-powered port with _“about 10 times faster”_ compiler performance. [TypeScript 6.0](https://devblogs.microsoft.com/typescript/announcing-typescript-6-0/)'s deprecations and [config changes](https://devblogs.microsoft.com/typescript/announcing-typescript-7-0-beta/#updates-since-5.x-and-new-behaviors-from-6.0) will help you upgrade smoothly from v5 to v7. There are also [changes to how to write your code](https://devblogs.microsoft.com/typescript/announcing-typescript-7-0-beta/#javascript-differences) to review. While v7 is considered _"close to production-ready"_, a stable programmatic API won't arrive till v7.1.
