Are you taking more reports?

It’s fairly minor, but I’d comment that the docs for template literals don’t mention details from the original pull request, such as a placeholder immediately followed by another placeholder matching a single character. The lack of documentation for this feature has made me hesitant to rely on it; Anders mentioned it in the PR, but it’s not clear how “fixed” that is.

For brevity's sake, we try not to put question-answers in the Handbook that can be discovered by simple experiment, but the inference description there is already long enough that we should add the one-character rule

Corollary note: Some documentation is very difficult to find because of the generic nature of certain terms. I'm thinking of "infer" which is almost impossible to find with Google. It might be interesting to have a searchable glossary in the documentation site.

Maybe "const modifier on type parameters" #51865

I found the override keyword in the release notes (not in handbook) today. It would be nice to have in the handbook as well so that it appears in algolia search results. 🙏
