Adaptation notes

Upgrade recommendation

The CloudTower API SDK supports backward compatibility. If SDK 2.9.0 supports up to CloudTower 3.0.0, it can also support CloudTower 2.8.0. It is recommended to upgrade the SDK first, and then upgrade CloudTower.

Compatibility

The following lists the compatible versions that can be upgraded with CloudTower. Versions after SDK 2.0 are recommended because these versions have more issues fixed and are more stable. If you need to use SDK versions earlier than 2.0 or specific SDK patch releases, you can check the corresponding SDK GitHub release pages.
