| **Windows - 9.1.1653.9590<br>Ubuntu 18 - 9.1.1457.1<br>Ubuntu 20 - 9.1.1457.1** | **Feature** | Key Value Store (KVS) | **Brief Description**: To ensure that the free page size is accurately calculated and used for auto-compaction purposes, all KVS databases will undergo regular defragmentation. <br>**Solution**: Customers can adjust the frequency of defragmentation using "MaxDefragFrequencyInMinutes".
| **Windows - 9.1.1653.9590<br>Ubuntu 18 - 9.1.1457.1<br>Ubuntu 20 - 9.1.1457.1** | **Feature** | Key Value Store (KVS) | **Brief Description**: The "IntrinsicValueThresholdInBytes" setting controls the size of long values stored in a record. If a value exceeds this size, it is stored as an Long Value ID (LVID) within the record. Presently, the default value is 0 which sets the size to 1024 bytes. However, in the future, the value will be changed to 5120 bytes to enable storage of long values up to approximately 5KB within a record. This change is expected to minimize LVID creation and mitigate the risk of LVID exhaustion. <br>**Solution**: The default value of the IntrinsicValueThresholdInBytes is set to 5120 bytes <br>**Workaround**: N/A
| **Windows - 9.1.1653.9590<br>Ubuntu 18 - 9.1.1457.1<br>Ubuntu 20 - 9.1.1457.1** | **Feature** | Key Value Store (KVS) | **Brief Description**: Legacy Compaction Settings (CompactionThresholdInMB, FreePageSizeThresholdInMB, and CompactionProbabilityInPercent) will be removed in the next major Service Fabric runtime version and functionality will be replaced with "FreePageSizeThresholdInPercent". These settings are deprecated and documented in the public API documentation to use the new "FreePageSizeThresholdInPercent" setting. <br>**Solution**: Customers should start using the new "FreePageSizeThresholdInPercent" property for customizing when offline auto-compaction occurs. <br>**Documentation Reference**:<ul><li>[CompactionProbabilityInPercent Property](https://learn.microsoft.com/en-us/dotnet/api/system.fabric.localesestoresettings.compactionprobabilityinpercent?view=azure-dotnet)</li><li>[FreePageSizeThresholdInMB Property](https://learn.microsoft.com/en-us/dotnet/api/system.fabric.localesestoresettings.freepagesizethresholdinmb?view=azure-dotnet)</li><li>[CompactionThresholdInMB Property](https://learn.microsoft.com/en-us/dotnet/api/system.fabric.localesestoresettings.compactionthresholdinmb?view=azure-dotnet)</li></ul>
| **Windows - 9.1.1653.9590<br>Ubuntu 18 - 9.1.1457.1<br>Ubuntu 20 - 9.1.1457.1** | **Feature** | Key Value Store (KVS) | **Brief Description**: Legacy Defragmentation setting "DefragThresholdInMB" will be removed in the next major Service Fabric runtime version as regular defragmentation will occur by default. This setting is deprecated and documented in the public API documentation to use the new setting "MaxDefragFrequencyInMinutes". <br>**Solution**: Customers should start using "MaxDefragFrequencyInMinutes" to adjust frequency of defragmentation going forward. <br>**Documentation Reference**: [MaxDefragFrequency Property](https://learn.microsoft.com/en-us/dotnet/api/system.fabric.localesestoresettings.maxdefragfrequencyinminutes?view=azure-dotnet#system-fabric-localesestoresettings-maxdefragfrequencyinminutes)

The optimal value for these settings will be decided internally and will not be allowed to be override. <br>**Solution**: Customers will not be able to override "IntrinsicValueThresholdInBytes" and "DatabasePageSizeInKB" these settings <br>**Documentation Reference**: <ul><li>[DatabasePageSizeInKB Property](https://learn.microsoft.com/en-us/dotnet/api/system.fabric.localesestoresettings.databasepagesizeinkb?view=azure-dotnet)</li><li>[IntrinsicValueThresholdInBytes Property](https://learn.microsoft.com/en-us/dotnet/api/system.fabric.localesestoresettings.intrinsicvaluethresholdinbytes?view=azure-dotnet)</li></ul>

To address this, we have updated the GRPC dependency to reference a more recent version, 3.1.0.

## Retirement and Deprecation Path Callouts
* As aligned with [Microsoft .NET and .NET Core - Microsoft Lifecycle | Microsoft Learn](https://learn.microsoft.com/en-us/lifecycle/products/microsoft-net-and-net-core), SF Runtime has dropped support for Net Core 3.1 as of December 2022. For supported versions see [Service Fabric supported Linux versions](https://learn.microsoft.com/en-us/azure/service-fabric/service-fabric-versions#current-versions-1) and migrate applications as needed.
