Azure Service Fabric 9.1 Release is now available!
We are excited to announce that the 9.1 release of the Service Fabric runtime has started rolling out to the various Azure regions along with tooling and SDK updates. The updates for .NET SDK, Java SDK, and Service Fabric runtimes can be downloaded from the links provided in Release Notes. The SDK, NuGet packages, and Maven repositories will be available in all regions within 7-10 days.
Key Announcements
- Azure Service Fabric will block deployments that do not meet Silver or Gold durability requirements starting from February 2023 (The date is extended from November 2022 to February 2023). Five VMs or more will be enforced with this change for newer clusters created from February 2023 to help avoid data loss from VM-level infrastructure requests for production workloads. VM count requirement is not changing for Bronze durability. Enforcement for existing clusters will be rolled out in the coming months.
For details see Durability characteristics of the cluster.
- Azure Service Fabric node types with VMSS durability of Silver or Gold should always have the property "virtualMachineProfile.osProfile.windowsConfiguration.enableAutomaticUpdates" set to false in the scale set model definition. Setting enableAutomaticUpdates to false will prevent unintended OS restarts due to the Windows updates like patching, which can impact the production workloads.
Instead, you should enable Automatic OS upgrades through VMSS OS Image updates by setting "enableAutomaticOSUpgrade" to true. With automatic OS image upgrades enabled on your scale set, an extra patching process through Windows Update is not required.

Breaking Change
BackupRestoreService: If a Service Fabric cluster has periodic backup enabled on any of the app/service/partition, post upgrade to 9.1.1390.9590, BRS will fail to deserialize old BackupMetadata. BRS will also stop taking backup and restore on the partition/service/app in question with changes in the new release even though the user app, cluster, and BRS shows healthy. Additional information regarding the breaking change is available in Release Notes
