Btw the next ruby release will be the 3.1, not 4. So '>= 2.4, < 4' is totally useless and could stand here for 10 years (the time to release ruby 4) without protecting you from any incompatibilities. My 2 cents.

1. It's not related to this PR, I don't change any versions.
2. 3.1 is less than 4 (3.1 < 4), and it's backward compatible with 3.x. It's Semver.
3. It's OK to not change version (at least upper one) for ten years.
