 ## Upgraded the MongoDB.Driver to version 3
 
-The [MongoDB.Driver](https://www.nuget.org/packages/MongoDB.Driver) introduces [breaking changes](https://www.mongodb.com/docs/drivers/csharp/current/upgrade/v3/), such as enforcing the `GuidRepresentationMode.V3` to be the only supported mode which affects the storing and loading of saga data. The persistence has been updated internally to accommodate these changes and uses this default mode unless explicitly configured.

-The enforcement for choosing a GUID representation mode has been introduced in the previous versions of the client. For saga data that requires to remain backward compatible, it is necessary to choose the GUID representation mode explicitly, either on a global level by overriding the `GuidSerializer` or by adjusting the class mappings.

-Here are a few examples to indicate some of the possible options. It is necessary to evaluate those options on a case by case basis to make sure previously stored sagas can still be retrieved. To learn more about serializing GUIDs in the .NET/C# Driver, see the [GUIDs page](https://www.mongodb.com/docs/drivers/csharp/current/fundamentals/serialization/guid-serialization/#std-label-csharp-guids).
