 # Changelog
 
+## 0.5.0
+- Added helper `seed::canvas()`, and `seed::canvas_context()` helper functions.
+- Fixed `Url` parsing (resolves issue with hash routing).
+- [BREAKING] `From<String> for Url` changed to `TryFrom<String> for Url`.
+- Fixed jumping cursor in inputs (#158) .
+- Added method `orders.after_next_render(Option<RenderTimestampDelta>)` (#207).
+- Fixed a bug with back/forward routing to the landing page (#296).
+- Deprecated `Init` struct, replacing it with `BeforeMount` and `AfterMount` structs to
+better denote state before and after mounting the `App` occurs.
+- Added a new function `builder` which replaces `build` as part of deprecating `Init`.
+- Added a new function `build_and_start` which replaces `finish` as part of deprecating `Init`.
+- Added `IntoInit`and `IntoAfterMount` traits. It is possible to use these
+in place of a closure or function to produce the corresponding `Init` and `AfterMount` structs.
+- Messages sent from `IntoAfterMount` will now be run after the routing message.
+- Added example `app_builder`.
+- `events::Listener` is included in `prelude`.
+- `()`s  have been replaced with structs - e.g. `GMs = ()` => `GMs = UndefinedGMs`.
+- `WindowEvents` alias changed to `WindowEventsFn` for consistency with other `*Fn`.
+- Commented builder and helper methods.
+
 ## v0.4.2
 - Added an `Init` struct, which can help with initial routing (Breaking)
 - The `routes` function now returns an `Option<Msg>` (Breaking)

+# Comparisons to React and Vue code
+
+On this page, we'll show equivalent code snippets in Seed, and other frameworks. For now, we
+ include examples from `React` and `Vue`. 
+The [TodoMVC example](https://github.com/seed-rs/seed/tree/master/examples/todomvc) can be used to 
+compare to [its implementation in other frameworks](http://todomvc.com/).
+
+Note that there are multiple ways to manage state in React, we've picked one where we store state
+in the top-level component, and use functional components thereafter.
+A closer structure match would be using it coupled with Redux. The Context API's an additional
+way to handle it. We're also using Typescript.
+
+## A simple template, ready for state management
+
+## React
+
+```jsx
+import * as React from "react"
+import * as ReactDOM from "react-dom"
+
+interface MainProps {}
+interface MainState {
+    val: number
+}
+
+class Main extends React.Component<MainProps, MainState> {
+    constructor(props) {
+        super(props)
+
+        this.state = {
+            val: 0
+        }
+
+        this.increment = this.increment.bind(this)
+    }
+    
+    increment() {
+        this.setState({val: this.state.val + 1})
+    }
+    
+    render() {
+        return (
+            <button onClick={() => this.state.increment()}>
+                {"Hello, World × " + this.state.val}
