This release includes the bug fixes described in this document. This release includes runtime, SDKs, and Windows Server Standalone deployments to run on-premises. This release will only be available through manual upgrades. Clusters set to automatic upgrades will not receive this release. For how to configure upgrades, please see or documentation. The following packages and versions are part of this release: | Service | Platform | Version | ||-|| |Service Fabric Runtime| Ubuntu 16 <br> Ubuntu 18 <br> Windows | 8.1.340.1 <br> 8.1.340.1 <br> 8.1.337.9590 | |Service Fabric for Windows Server|Service Fabric Standalone Installer Package | 8.1.337.9590 | |.NET SDK |Windows .NET SDK <br> Microsoft.ServiceFabric <br> Reliable Services and Reliable Actors <br> ASP.NET Core Service Fabric integration| 5.1.337 <br> 8.1.337 <br> 8.1.337 <br> 8.1.337 | |Java SDK |Java for Linux SDK | 1.0.6 | |Service Fabric PowerShell and CLI | AzureRM PowerShell Module <br> SFCTL | 0.3.15 <br> 11.1.0 | Microsoft Azure Service Fabric 8.1 Third Refresh Update (3.1) Release Notes 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).<br/> Following scenarios are impacted:<br/> An application with guest executables or containers is created or upgraded in an Service Fabric 7.1+ cluster.<br/> The cluster is then downgraded to a previous Service Fabric runtime version (e.g. Service Fabric 7.0).<br/> The application fails to activate.<br/> A cluster upgrade from pre-SF 7.1 version to Service Fabric 7.1+ version is in progress.<br/> In parallel with the Service Fabric runtime upgrade, an application with guest executables or containers is created or upgraded.<br/> The Service Fabric runtime upgrade starts rolling back (due to any reason) to the pre-SF 7.1 version.<br/> The application fails to activate.<br/> 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.<br/> The simplest mitigation, when possible, is to delete and recreate the application in Service Fabric 7.0.<br/> The other option is to upgrade the application in Service Fabric 7.0 (for example, with a version only change).<br/> If the application is stuck in rollback, the rollback has to be first completed before the application can be upgraded again. .NET Core 2.x Support*: .NET Core runtime LTS 2.1 runtime is out of support as of Aug 21, 2021, and .NET Core runtime 2.2 is out of support from Dec 2019. Service Fabric releases after those dates will drop support for Service Fabric apps running with .NET Core 2.1, and .NET Core 2.2 runtimes respectively. Current apps running on .NET Core

runtime will continue to work, but requests for investigations or request for changes will no longer receive support. Service Fabric .NET SDK will take a dependency on .NET runtime 3.x features to support Service Fabric .NET Core apps. Ubuntu 16.04 Support*: Ubuntu 16.04 LTS reached it's 5-year end-of-life window on April 30, 2021. Service Fabric runtime will drop support for Ubuntu 16.04 after that date as well. Current applications running on it will continue to work, but requests for investigations or requests for change will no longer receive support. We recommend moving your applications to Ubuntu 18.04. | Versions | IssueType | Description | Resolution | |-|-|-|-| | Windows - 8.1.321.9590<br>Ubuntu 16 - 8.1.323.1<br>Ubuntu 18 - 8.1.323.1 | Bug | Add constructor in PartitionMetricLoadDescription class without auxiliary fields for backward compatibility | Brief Description: The following constructor has been added back to the class - - for supporting backward compatibility for the customers who are using Service Fabric SDK 8.0 and earlier version but want to upgrade their cluster to Service Fabric Runtime 8.1<br><sub>public PartitionMetricLoadDescription(Guid partitionId,<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;IList<MetricLoadDescription> primaryReplicaLoadEntries,<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;IList<MetricLoadDescription> secondaryReplicasOrInstancesLoadEntries,<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;IList<ReplicaMetricLoadDescription> secondaryReplicaOrInstanceLoadEntriesPerNode)</sub><br>Impact: Customers using the class PartitionMetricLoadDescription Class were impacted when they only upgraded the Service Fabric runtime version to 8.1 but didn't update the Service Fabric SDK <br>Fix: Re-addition of the old constructor as mentioned in the description. | The table below is an overview of the direct links to the packages associated with this release.
