 > WebJobs.Extensions.DurableTask v3 uses the latest version of the Azure Storage SDK, which has a different text encoding (Base64) when compared to the one used in v2 (UTF-8). If you need to downgrade from v3.x to v2.x, to ensure backward compatibility, use at least **[v2.13.5](https://github.com/Azure/azure-functions-durable-extension/releases/tag/v2.13.5)**. For .NET out-of-process users with Microsoft.Azure.Functions.Worker.Extensions.DurableTask, downgrade to **[v1.1.5](https://github.com/Azure/azure-functions-durable-extension/releases/tag/v1.1.5Worker.Extensions.DurableTask)** or higher if reverting from v1.2.x or higher.
