react - npm Package Versions

0.12.2 (December 18, 2014)

React Core

• Added support for more HTML attributes: formAction, formEncType, formMethod, formTarget, marginHeight, marginWidth
• Added strokeOpacity to the list of unitless CSS properties
• Removed trailing commas (allows npm module to be bundled and used in IE8)
• Fixed bug resulting in error when passing undefined to React.createElement - now there is a useful warning

React Tools

• JSX-related transforms now always use double quotes for props and displayName

0.12.1 (November 18, 2014)

React Tools

• Types transform updated with latest support
• jstransform version updated with improved ES6 transforms
• Explicit Esprima dependency removed in favor of using Esprima information exported by jstransform

0.12.0 (October 28, 2014)

React Core

Breaking Changes

• key and ref moved off props object, now accessible on the element directly
• React is now BSD licensed with accompanying Patents grant
• Default prop resolution has moved to Element creation time instead of mount time, making them effectively static
• React.__internals is removed - it was exposed for DevTools which no longer needs access
• Composite Component functions can no longer be called directly - they must be wrapped with React.createFactory first. This is handled for you when using JSX.

New Features

• Spread operator ({...}) introduced to deprecate this.transferPropsTo
• Added support for more HTML attributes: acceptCharset, classID, manifest

Deprecations

• React.renderComponent --> React.render
• React.renderComponentToString --> React.renderToString
• React.renderComponentToStaticMarkup --> React.renderToStaticMarkup
• React.isValidComponent --> React.isValidElement
• React.PropTypes.component --> React.PropTypes.element
• React.PropTypes.renderable --> React.PropTypes.node
• DEPRECATED React.isValidClass
• DEPRECATED instance.transferPropsTo
• DEPRECATED Returning false from event handlers to preventDefault
• DEPRECATED Convenience Constructor usage as function, instead wrap with React.createFactory
• DEPRECATED use of key={null} to assign implicit keys

Bug Fixes

• Better handling of events and updates in nested results, fixing value restoration in "layered" controlled components
• Correctly treat event.getModifierState as case sensitive
• Improved normalization of event.charCode
• Better error stacks when involving autobound methods
• Removed DevTools message when the DevTools are installed
• Correctly detect required language features across browsers
• Fixed support for some HTML attributes:
  • list updates correctly now
  • scrollLeft, scrollTop removed, these should not be specified as props
• Improved error messages

React With Addons

New Features

• React.addons.batchedUpdates added to API for hooking into update cycle

Breaking Changes

• React.addons.update uses assign instead of copyProperties which does hasOwnProperty checks. Properties on prototypes will no longer be updated correctly.

Bug Fixes

• Fixed some issues with CSS Transitions

JSX

Breaking Changes

• Enforced convention: lower case tag names are always treated as HTML tags, upper case tag names are always treated as composite components
• JSX no longer transforms to simple function calls

New Features

• @jsx React.DOM no longer required
• spread ({...}) operator introduced to allow easier use of props

Bug Fixes

• JSXTransformer: Make sourcemaps an option when using APIs directly (eg, for react-rails)

0.11.2 (September 16, 2014)

React Core

New Features

• Added support for <dialog> element and associated open attribute
• Added support for <picture> element and associated media and sizes attributes
• Added React.createElement API in preparation for React v0.12
  • React.createDescriptor has been deprecated as a result

JSX

• <picture> is now parsed into React.DOM.picture

React Tools

• Update esprima and jstransform for correctness fixes
• The jsx executable now exposes a --strip-types flag which can be used to remove TypeScript-like type annotations
  • This option is also exposed to require('react-tools').transform as stripTypes

0.11.1 (July 24, 2014)

React Core

Bug Fixes

• setState can be called inside componentWillMount in non-DOM environments
• SyntheticMouseEvent.getEventModifierState correctly renamed to getModifierState
• getModifierState correctly returns a boolean
• getModifierState is now correctly case sensitive
• Empty Text node used in IE8 innerHTML workaround is now removed, fixing rerendering in certain cases

JSX

• Fix duplicate variable declaration in JSXTransformer (caused issues in some browsers)

0.11.0 (July 17, 2014)

React Core

Breaking Changes

• getDefaultProps() is now called once per class and shared across all instances
• MyComponent() now returns a descriptor, not an instance
• React.isValidComponent and React.PropTypes.component validate descriptors, not component instances
• Custom propType validators should return an Error instead of logging directly

New Features

• Rendering to null
• Keyboard events include normalized e.key and e.getModifierState() properties
• New normalized onBeforeInput event
• React.Children.count has been added as a helper for counting the number of children

Bug Fixes

• Re-renders are batched in more cases
• Events: e.view properly normalized
• Added Support for more HTML attributes (coords, crossOrigin, download, hrefLang, mediaGroup, muted, scrolling, shape, srcSet, start, useMap)
• Improved SVG support
  • Changing className on a mounted SVG component now works correctly
  • Added support for elements mask and tspan
  • Added support for attributes dx, dy, fillOpacity, fontFamily, fontSize, markerEnd, markerMid, markerStart, opacity, patternContentUnits, patternUnits, preserveAspectRatio, strokeDasharray, strokeOpacity
• CSS property names with vendor prefixes (Webkit, ms, Moz, O) are now handled properly
• Duplicate keys no longer cause a hard error; now a warning is logged (and only one of the children with the same key is shown)
• img event listeners are now unbound properly, preventing the error "Two valid but unequal nodes with the same data-reactid"
• Added explicit warning when missing polyfills

React With Addons

• PureRenderMixin: a mixin which helps optimize "pure" components
• Perf: a new set of tools to help with performance analysis
• Update: New $apply command to transform values
• TransitionGroup bug fixes with null elements, Android

React NPM Module

• Now includes the pre-built packages under dist/.
• envify is properly listed as a dependency instead of a peer dependency

JSX

• Added support for namespaces, eg <Components.Checkbox />
• JSXTransformer
  • Enable the same harmony features available in the command line with <script type="text/jsx;harmony=true">
  • Scripts are downloaded in parallel for more speed. They are still executed in order (as you would expect with normal script tags)
  • Fixed a bug preventing sourcemaps from working in Firefox

React Tools Module

• Improved readme with usage and API information
• Improved ES6 transforms available with --harmony option
• Added --source-map-inline option to the jsx executable
• New transformWithDetails API which gives access to the raw sourcemap data

0.10.0 (March 21, 2014)

React Core

New Features

• Added warnings to help migrate towards descriptors
• Made it possible to server render without React-related markup (data-reactid, data-react-checksum). This DOM will not be mountable by React. Read the docs for React.renderComponentToStaticMarkup
• Added support for more attributes:
  • srcSet for <img> to specify images at different pixel ratios
  • textAnchor for SVG

Bug Fixes

• Ensure all void elements don’t insert a closing tag into the markup.
• Ensure className={false} behaves consistently
• Ensure this.refs is defined, even if no refs are specified.

Addons

• update function to deal with immutable data. Read the docs

react-tools

• Added an option argument to transform function. The only option supported is harmony, which behaves the same as jsx --harmony on the command line. This uses the ES6 transforms from jstransform.
