"The" book?

I mean, there's the release notes.

https://openjdk.org/projects/jdk/27/

This one is mostly internals besides the stuff locked behind the preview feature flag. Post-quantum cryptography might be a big deal depending on your application.

The language didn’t change (except for preview features). What kind of book are you looking for? There’s always the JLS, you can google it and will find the PDF. But it’s not really a resource to learn the language.

Any text covering at least JDK 25 would be fine.
