+
+
+### BREAKING CHANGES
+
+* **watch:** `watch` behavior has been adjusted.
+
+    - When using the `watch(source, callback, options?)` signature, the
+      callback now fires lazily by default (consistent with 2.x
+      behavior).
+
+      Note that the `watch(effect, options?)` signature is still eager,
+      since it must invoke the `effect` immediately to collect
+      dependencies.
+
+    - The `lazy` option has been replaced by the opposite `immediate`
+      option, which defaults to `false`. (It's ignored when using the
+      effect signature)
+
+    - Due to the above changes, the `watch` option in Options API now
+      behaves exactly the same as 2.x.
+
+    - When using the effect signature or `{ immediate: true }`, the
+      intital execution is now performed synchronously instead of
+      deferred until the component is mounted. This is necessary for
+      certain use cases to work properly with `async setup()` and
+      Suspense.
+
+      The side effect of this is the immediate watcher invocation will
+      no longer have access to the mounted DOM. However, the watcher can
+      be initiated inside `onMounted` to retain previous behavior.

 The current codebase has basic feature parity with v2.x, together with the changes proposed in [merged RFCs](https://github.com/vuejs/rfcs/pulls?q=is%3Apr+is%3Amerged+label%3A3.x). There is a simple webpack-based setup with Single-File Component support available [here](https://github.com/vuejs/vue-next-webpack-preview).
 
-At this stage, the only major work left is server-side rendering, which we are actively working on. In the meanwhile, we would like our users to start building small experimental apps using the alpha releases to help us identify bugs and stabilize the implementation.
-
 Please note that there could still be undocumented behavior inconsistencies with 2.x. When you run into such a case, please make sure to first check if the behavior difference has already been proposed in an existing RFC. If the inconsistency is not part of an RFC, then it's likely unintended, and an issue should be opened (please make sure to use the [issue helper](https://new-issue.vuejs.org/?repo=vuejs/vue-next) when opening new issues).
 
+## TODOs as of 3.0.0-alpha.5
+
+- Suspense support in SSR
+- SSR Hydration mismatch handling
+- SSR vnode directive support
+- SSR integration tests
+- 2.x compatible async component support

 ## Known Issues
 
 - There is currently no way to attach custom instance properties via `Vue.prototype`.
