Composer Environment Rollback Targets

The SoftwareConfig schema now includes a new imageVersionRollbackTargets array. This array contains ImageVersionRollbackTarget objects, each detailing an imageVersion and its lastActiveTime. These new fields are Output only, providing valuable insights into available rollback points for your Composer environments. The API change is marked as breaking because these newly introduced properties (imageVersion and lastActiveTime within ImageVersionRollbackTarget, and imageVersionRollbackTargets itself) are explicitly defined as readOnly. Developers should ensure their clients do not attempt to set values for these properties, as such attempts will now fail.
