4.0.0 (2026-06-03)
BREAKING CHANGES
- This drops support for Nodejs 20, and drops the polyfill for
Object.groupBy - instead calling it directly. This means this version
will fail to run in Nodejs 20 contexts without an Object.groupBy polyfill.
Going forward and issues relating to support for Nodejs 20 will be
closed, our minimum supported Nodejs version is 22 - which we will aim
to support until April 2027, when it becomes EOL.
