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 20 <br> Windows | 10.1.1885.1 <br> 10.1.1951.9590 | | Service Fabric for Windows Server | Service Fabric Standalone Installer Package | 10.1.1951.9590 | | .NET SDK | Windows .NET SDK <br> Microsoft.ServiceFabric <br> Reliable Services and Reliable Actors <br> ASP.NET Core Service Fabric integration | 7.1.1951 <br> 10.1.1951 <br> 7.1.1951 <br> 7.1.1951 | | Java SDK | Java for Linux SDK | 1.0.6 | | Service Fabric PowerShell and CLI | AzureRM PowerShell Module <br> SFCTL | 0.3.15 <br> 11.0.1 | | Versions | IssueType | Description | Resolution | |-|-|-|-| | Windows -<br>10.1.1951.9590 <br> Ubuntu 20 -<br>10.1.1885.1 | Feature | Key Value Store (KVS) | Brief Description: Increase MaxVerPages to 32768. <br> Increasing the value of MaxVerPages enables us to allow operations that would require bigger ESE Version store size such as logical builds of larger databases and reduce the number of incidents caused due to Version Store Out of Memory. <br> Solution: The default value of MaxVerPages is set to 32768. | | Windows -<br>10.1.1951.9590 <br> Ubuntu 20 -<br>10.1.1885.1 | Bug | CRM | Brief Description: It was observed that the number of replicas which can be hosted on a Service Fabric node was unbounded. This may result in node failure when Service Fabric attempts to perform a high number of parallel operations like database transactions for its own data persistence which has a hard limit. we are Introducing maximum limit of 25k which is default value. | | Windows -<br>10.1.1951.9590 <br> Ubuntu 20 -<br>10.1.1885.1 | Bug | FabricHost | Brief Description: FabricHost.exe will send periodic heartbeat requests to Fabric.exe, and if don't receive success heartbeat response for 5 minutes, FabricHost will restart Fabric. This FabricHost restart Fabric will happen once for each Fabric.exe process. The heartbeat and restart are under a config. | | Windows -<br>10.1.1951.9590 <br> Ubuntu 20 -<br>10.1.1885.1 | Feature | EA Role | Brief Description: In this version we introduced ElevatedAdmin (EA) role dSTS support, meaning that clients presenting dSTS token with the right claims can be authenticated as ElevatedAdmin client. | | Windows -<br>10.1.1951.9590 <br> Ubuntu 20 -<br>10.1.1885.1 | Feature | EA Role | Brief Description: In this version we introduced ElevatedAdmin (EA) role support for REST API

In previous version, clients executing REST API calls with EA cert presented were authorized as User and not ElevatedAdmin role. | | Windows -<br>10.1.1951.9590 <br> Ubuntu 20 -<br>10.1.1885.1 | Bug | ESE Store | Brief Description: In Service Fabric versions starting with 9.1CU3, 9.0CU8 released in March 2023 and before 9.1CU8, 10.0CU2, 10.1CU1, November 2023 (9.1CU8, 10.0CU2, 10.1CU1) the FreePageSizeThresholdInPercent is invalid for any services based on the Reliable Actors with the KVSActorStateProvider or any services overriding the LocalEseStoreSettings. <br> Solution: Correct default setting will now be applied for all services and regular auto-compaction based on the database meeting the FreePageSizeInPercent Threshold will occur leading to reduction in unused space taken up by databases and thus reduce database bloat. | Service Fabric runtime will discontinue support for the Java SDK soon. For a smooth transition, we strongly recommend users to shift to Azure Service Fabric .NET SDK. If your current setup is based on the Service Fabric Java SDK, we suggest starting migration plans to smoothly switch to the Azure Service Fabric .NET SDK. Although applications using the Java SDK will continue to work, we highly recommend adopting the SF .NET SDK for optimal outcomes. Ubuntu 18.04 LTS has reached its 5-year end-of-life window on June-2023. Service Fabric runtime has dropped support for 18.04 LTS after the published date, and we recommend moving your clusters and applications to supported versions listed here: Previously communicated, Service Fabric runtime had planned to remove Service Fabric runtime version 6.4 packages and older, as well as SDK version 3.3 packages and older, from the package Download Center in July 2023. We would like to inform you that this timeline has been extended, and the removal will now take place in January 2024. Service Fabric runtime will soon be archiving and removing Service Fabric runtime versions less than 7.2 and older, as well as the corresponding SDK version 4.2 packages and older from the package Download Center. Archiving/Removing will affect application scaling and re-imaging of virtual machines in a Service Fabric Cluster running on unsupported versions. After older versions are removed/archived, this may cause failure while rolling back when the current in-progress upgrade has errors. To prevent disruption of workloads, create a new cluster using the following steps: * Install the supported version of Service Fabric SDK based on the Runtime version installed on the cluster.
