The MongoDB Atlas Administration API has undergone significant changes to provide a better developer experience. The new Versioned API offers a predictable and consistent experience with API changes, giving developers better visibility into new features and changes through the Atlas Administration API changelog. Breaking changes are now only introduced in new resource versions, allowing for seamless upgrades without affecting production code. Additionally, the API supports Service Accounts as a new authentication method using OAuth2.0 protocol, and provides specific resource versions represented by dates, ensuring minimal workflow disruptions during migration. The updated documentation and improved context provide enhanced visibility and context for all stable and deprecated resource versions. A new Go SDK has also been introduced to support full endpoint coverage, flexibility, ease of use, immediate access to updates, and streamlined development process.
