TypeScript: Documentation - TypeScript 5.8
TypeScript 5.8 introduces a stable --module node18 flag. For users who are fixed on using Node.js 18, this flag provides a stable point of reference that does not incorporate certain behaviors that are in --module nodenext.

We also felt that it was time that tsc --init initialized with a few more prescriptive settings than we already enable. We looked at some common pain points and papercuts users have when they create a new TypeScript project. For example, most users write in modules (not global scripts), and --moduleDetection can force TypeScript to treat every implementation file as a module.

Announcing TypeScript 5.9 - TypeScript
August 1, 2025 - Today we are excited to announce the release of TypeScript 5.9! If you’re not familiar with TypeScript, it’s a language that builds on JavaScript by adding syntax for types. With types, TypeScript makes it possible to check your code to avoid bugs ahead of time.

This allowed us to get feedback and harden our file-watching implementation against most of these platform-specific gotchas. As TypeScript has needed to scale to larger codebases, and has improved in this area, we felt swapping to file system events as the default would be a worthwhile investment.

r/learnjavascript on Reddit: How does the typescript-eslint project generate its changelogs?
July 6, 2022 -
Hi. I'm maintaining a small monorepo and I'd like to learn techniques from large, mature projects like typescript-eslint. I assume they automate changelogs from commit logs and/or PRs, but I can't figure out how they do it by looking at their source code. I do know of tools like release-it that helps automate the process; do the typescript-eslint maintainers use such a tool, or use a homegrown one?
Edit: Nevermind, Brad Zacher (who maintains the project) replied immediately :)

TypeScript: Documentation - TypeScript 5.4
Here, TypeScript decided that it wasn’t “safe” to assume that url was actually a URL object in our callback function because it was mutated elsewhere; however, in this instance, that arrow function is always created after that assignment to url, and it’s also the last assignment to url.

TypeScript did not infer a type predicate for score => !!score, and rightly so: if this returns true then score is a number. But if it returns false, then score could be either undefined or a number (specifically, 0). This is a real bug: if any student got a zero on the test, then filtering ...

When you upgrade TypeScript, you’re also forced to handle changes to TypeScript’s built-in declaration files, and this can be a challenge when the DOM APIs change as frequently as they do.
