1 +## 0.9.0 (February 20, 2014)

2 +

3 +### React Core

4 +

5 +#### Breaking Changes

6 +

7 +- The lifecycle methods `componentDidMount` and `componentDidUpdate` no longer receive the root node as a parameter; use `this.getDOMNode()` instead

8 +- Whenever a prop is equal to `undefined`, the default value returned by `getDefaultProps` will now be used instead

9 +- `React.unmountAndReleaseReactRootNode` was previously deprecated and has now been removed

10 +- `React.renderComponentToString` is now synchronous and returns the generated HTML string

11 +- Full-page rendering (that is, rendering the `<html>` tag using React) is now supported only when starting with server-rendered markup

12 +- On mouse wheel events, `deltaY` is no longer negated

13 +- When prop types validation fails, a warning is logged instead of an error thrown (with the production build of React, type checks are now skipped for performance)

14 +- On `input`, `select`, and `textarea` elements, `.getValue()` is no longer supported; use `.getDOMNode().value` instead

15 +

16 +#### New Features

17 +

18 +- React now never rethrows errors, so stack traces are more accurate and Chrome's purple break-on-error stop sign now works properly

19 +- Added support for SVG tags `defs`, `linearGradient`, `polygon`, `radialGradient`, `stop`

20 +- Added support for more attributes:

21 + - `crossOrigin` for CORS requests

22 + - `download` and `hrefLang` for `<a>` tags

23 + - `mediaGroup` and `muted` for `<audio>` and `<video>` tags

24 + - `noValidate` and `formNoValidate` for forms

25 + - `property` for Open Graph `<meta>` tags

26 + - `sandbox`, `seamless`, and `srcDoc` for `<iframe>` tags

27 + - `scope` for screen readers

28 + - `span` for `<colgroup>` tags

29 +- Added support for defining `propTypes` in mixins

30 +- Added `any`, `arrayOf`, `component`, `oneOfType`, `renderable`, `shape` to `React.PropTypes`

31 +- Added support for `statics` on component spec for static component methods

32 +- On all events, `.currentTarget` is now properly set

33 +- On keyboard events, `.key` is now polyfilled in all browsers for special (non-printable) keys

34 +- On clipboard events, `.clipboardData` is now polyfilled in IE

35 +- On drag events, `.dragTransfer` is now present

36 +- Added support for `onMouseOver` and `onMouseOut` in addition to the existing `onMouseEnter` and `onMouseLeave` events

37 +- Added support for `onLoad` and `onError` on `<img>` elements

38 +- Added support for `onReset` on `<form>` elements

39 +- The `autoFocus` attribute is now polyfilled consistently on `input`, `select`, and `textarea`

40 +

41 +#### Bug Fixes

42 +

43 +- React no longer adds an `__owner__` property to each component's `props` object; passed-in props are now never mutated

44 +- When nesting top-level components (e.g., calling `React.renderComponent` within `componentDidMount`), events now properly bubble to the parent component

45 +- Fixed a case where nesting top-level components would throw an error when updating

46 +- Passing an invalid or misspelled propTypes type now throws an error

47 +- On mouse enter/leave events, `.target`, `.relatedTarget`, and `.type` are now set properly

48 +- On composition events, `.data` is now properly normalized in IE9 and IE10

49 +- CSS property values no longer have `px` appended for the unitless properties `columnCount`, `flex`, `flexGrow`, `flexShrink`, `lineClamp`, `order`, `widows`

50 +- Fixed a memory leak when unmounting children with a `componentWillUnmount` handler

51 +- Fixed a memory leak when `renderComponentToString` would store event handlers

52 +- Fixed an error that could be thrown when removing form elements during a click handler

53 +- Boolean attributes such as `disabled` are rendered without a value (previously `disabled="true"`, now simply `disabled`)

54 +- `key` values containing `.` are now supported

55 +- Shortened `data-reactid` values for performance

56 +- Components now always remount when the `key` property changes

57 +- Event handlers are attached to `document` only when necessary, improving performance in some cases

58 +- Events no longer use `.returnValue` in modern browsers, eliminating a warning in Chrome

59 +- `scrollLeft` and `scrollTop` are no longer accessed on document.body, eliminating a warning in Chrome

60 +- General performance fixes, memory optimizations, improvements to warnings and error messages

61 +

62 +### React with Addons

63 +

64 +- `React.addons.TestUtils` was added to help write unit tests

65 +- `React.addons.TransitionGroup` was renamed to `React.addons.CSSTransitionGroup`

66 +- `React.addons.TransitionGroup` was added as a more general animation wrapper

67 +- `React.addons.cloneWithProps` was added for cloning components and modifying their props

68 +- Bug fix for adding back nodes during an exit transition for CSSTransitionGroup

69 +- Bug fix for changing `transitionLeave` in CSSTransitionGroup

70 +- Performance optimizations for CSSTransitionGroup

71 +- On checkbox `<input>` elements, `checkedLink` is now supported for two-way binding

72 +

73 +### JSX Compiler and react-tools Package

74 +

75 +- Whitespace normalization has changed; now space between two tags on the same line will be preserved, while newlines between two tags will be removed

76 +- The `react-tools` npm package no longer includes the React core libraries; use the `react` package instead.

77 +- `displayName` is now added in more cases, improving error messages and names in the React Dev Tools

78 +- Fixed an issue where an invalid token error was thrown after a JSX closing tag

79 +- `JSXTransformer` now uses source maps automatically in modern browsers

80 +- `JSXTransformer` error messages now include the filename and problematic line contents when a file fails to parse
