Announcing TypeScript 4.3 Beta — It dropped on April 1 but it was no joke. Notably, 4.3 introduces a override keyword to make it clear when you’re overriding a method rather than adding a new one. There are also template string type improvements, and methods and accessors can be given #private names.
