+* Upgrade version of ArmoniK Admin Gui from `0.11.8` to `0.12.0` [Changelog](https://github.com/aneoconsulting/ArmoniK.Admin.GUI/releases/0.12.0).
+* Upgrade version of ArmoniK Extensions Csharp from `0.14.6` to `0.17.0` [Changelog](https://github.com/aneoconsulting/ArmoniK.Extensions.Csharp/releases/tag/0.17.0).
+
+There are some very important modifications and new functionality in this version. 
+
+The most consequential is probably the addition of a new service, the Pod Cost Deletion,
+which will imply **a change of the infrastructure**. This service will advise Kubernetes, 
+in case of downscaling, to destroy, in priority, the pods with the lower cost which means
+with the less time it has been up.
+
+Another important modification is the removal of the legacy Grpc core for .Net used in Extensions.Csharp 
+to be able to support legacy system using .Net 4.8. Nowadays the Extensions are using Grpc .Net. 
+**Be careful**, due to the release of the use of grpc Core (deprecated) and its replacement with grpc .Net, 
+a consequence is that the client may not use exactly the same type of submission protocol. 
+Indeed, http2 was previously provided by grpc core and is now managed by the system. 
+Unfortunately, this is only available on Microsoft Windows from the version Microsoft Windows 11 or
+Microsoft Server 2019. For this to work on previous versions (including Microsoft Windows 10),
+a fall back to the grpc web protocol was implemented. Therefore, there may be slightly different
+behavior on Microsoft Windows depending of the OS version.
+
+The Admin Gui has been update to the newer LTS version of the Angular framework and contains 
+tons of small improvements and bugs corrections.
+
+
+## [v2.19.5](https://github.com/aneoconsulting/armonik/tree/v2.19.5) (2024-04-26)
+
+Changed
+-
+* Upgrade version of ArmoniK Extensions Csharp from `0.14.4` to `0.14.5` [Changelog](https://github.com/aneoconsulting/ArmoniK.Extensions.Csharp/releases).
