What is the purpose of a CHANGELOG.md file in a Node.js project, and what should typically be included in each entry?
BeginnerAnswer
A CHANGELOG.md documents notable changes for each released version in a human-readable format, typically grouped by category (Added, Changed, Fixed, Removed, Breaking Changes) and version number, letting users and downstream consumers of a package quickly understand what changed between versions without needing to read through the full commit history themselves, which is especially valuable when deciding whether it's safe to upgrade.

- Support for refresh token rotation
### Fixed
- Off-by-one error in pagination results
