+## Leverage New Types
+
+The `durable-functions` package now exposes new types that weren't previously exported! This allows you to more strongly type your functions and provide stronger type safety for your orchestrations, entities, and activities! This also improves intellisense for authoring these functions.
+
+Below are some of the new exported types:
+
+- `OrchestrationHandler`, and `OrchestrationContext` for orchestrations
+- `EntityHandler` and `EntityContext` for entities
+- `ActivityHandler` for activities
+- `DurableClient` class for client functions
+
+> [!TIP]
+> Strongly type your functions by leveraging new types exported from the `durable-functions` package!

+# Troubleshooting
+
+If you see the following error when running your orchestration code, make sure you are running on the at least `v4.16.5` of the [Azure Functions Runtime](../functions-versions.md?tabs=v4&pivots=programming-language-javascript) or at least `v4.0.5095` of [Azure Functions Core Tools](../functions-run-local.md?tabs=v4) if running locally.
