-**IMPORTANT: Please update to this version of `firebase-functions` if you are using Node.js 10 functions, otherwise your functions will break in production.**
+- Adds support for defining max number of instances for a function. Example:
 
-- Prevents deployment and runtime issues caused by upcoming changes to Cloud Functions infrastructure for Node.js 10 functions. (Issue #630)
-- Adds support for writing scheduled functions under handler namespace.
+  ```
+  functions.runWith({
+    maxInstances: 10
+  }).https.onRequest(...);
+  ```
+
+  Learn more about max instances in the [Google Cloud documentation.](https://cloud.google.com/functions/docs/max-instances)
+
+- Fixes TypeScript build error when `package-lock.json` is present by updating dependencies (Issue #637).
