+# 0.9.0 (27 November 2020)
+
+This release introduces support for catching `JSError` instances in Swift from throwing JavaScript
+functions. This is possible thanks to the new `JSThrowingFunction` and `JSThrowingObject` classes.
+The former can only be called with `try`, while the latter will expose all of its member functions
+as throwing. Use the new `throws` property on `JSFunction` to convert it to `JSThrowingFunction`,
+and the new `throwing` property on `JSObject` to convert it to `JSThrowingObject`.
+
+**Closed issues:**
+
+- Support JS errors ([#37](https://github.com/swiftwasm/JavaScriptKit/issues/37))
+
+**Merged pull requests:**
