Current Breaking Changes

Also, see feature items for breaking change details.

• Guest Executable and Container Applications: Guest executable and container applications created or upgraded in Service Fabric clusters with runtime versions 7.1+ are incompatible with prior Service Fabric runtime versions (e.g. Service Fabric 7.0).
  Following scenarios are impacted:
  
  • An application with guest executables or containers is created or upgraded in an Service Fabric 7.1+ cluster.
    The cluster is then downgraded to a previous Service Fabric runtime version (e.g. Service Fabric 7.0).
    The application fails to activate.
  • A cluster upgrade from pre-SF 7.1 version to Service Fabric 7.1+ version is in progress.
    In parallel with the Service Fabric runtime upgrade, an application with guest executables or containers is created or upgraded.
    The Service Fabric runtime upgrade starts rolling back (due to any reason) to the pre-SF 7.1 version.
    The application fails to activate.
    To avoid issues when upgrading from a pre-SF 7.1 runtime version to an Service Fabric 7.1+ runtime version, do not create or upgrade applications with guest executables or containers while the Service Fabric runtime upgrade is in progress.
  • The simplest mitigation, when possible, is to delete and recreate the application in Service Fabric 7.0.
  • The other option is to upgrade the application in Service Fabric 7.0 (for example, with a version only change).
    If the application is stuck in rollback, the rollback has to be first completed before the application can be upgraded again.
