• #3689 fix <select v-model> initial value out of sync in IE/Edge
• #3693 fix prop default value not used when using propsData
• #3729 fix <option value=""> cannot be selected with v-model
• #3730 fix iOS 10 UIWebView broken update issue

v1.0.27

Fixed

• #3183 fix prop validation failure with propsData (#3193 by @kazupon)
• #3184 textarea with v-pre attr should skip compile (#3202 by @hylin)
• #3187 fix error processing single-letter hyphenated props
• #3204 fix $refs not updated correctly inside v-if (#3217 by @kazupon)
• #3210 fix filter arguments parsing when it contains spaces (#3734 by @defcc)
• #3273 handle backticks in expression (#3273 by @skyronic)
• #3307 v-model checkbox updates should replace the bound array
• #3668 fix required prop warning when using propsData

v2.0.0-rc.6

Fixed

• #3610 fix data observation converting prototype keys
• #3642 fix incorrect duplicate slot warning detection
• #3657 fix style binding array syntax not updating due to toObject mutating merged objects
• #3663 fix parsing multi-line attribute values in DOM template in IE

v2.0.0-rc.5

New

• Custom directives now get a new hook: inserted, which will be called when the bound element has been inserted into its parent node. (Note this only guarantees parent node presence but not in-document)
• SSR hydration now allows the client to hydrate a server-rendered node when it has no children. (Previously it would throw an error and bail out with a full re-render) This allows the server to render a static "app shell" and let the client pick it up.

Fixed

• Reverted custom directive bind call timing due to it leading to incorrect v-show property switch timing during initial render.
• #3556 fix v-on patching for cloned slot nodes
• #3559 remove unnecessary appear check in v-show
• #3595 fix incorrect duplicate slot warning when they are under v-if/v-else
• #3611 fix v-for patching error by keying nested children by default

v2.0.0-rc.4

New

• Async component function now supports returning a Promise. Note if you are using async components with vue-router you need to update vue-router too.

Fixed

• Fixed hot-reload issues when editing static elements
• #3491 fix vdom patch: properly teardown stable directives
• #3506 fix transition end detection (only check events on target element)
• #3516 fix v-model codegen for non-input components with type prop
• #3518 fix event initialization on reused slot nodes
• #3526 fix text parser for multi-line mustache tags
• #3529 ensure custom directive bind hook is called after element insertion
• #3533 fix vdom patch: DOM insertion reference node error on reused static node

v2.0.0-rc.3

New

• Vue.set and Vue.delete is now also exposed on Vue instances as this.$set and this.$delete. Note this is different from the 1.x counterparts: they are simply aliases to the global API.

  This change eliminates the need to import/require Vue just to access these two methods, and makes it easier to pre-compile standalone Vue components.

• Added a warning when mounting the root instance to body or html. This is no longer recommended in 2.0.

Fixed

• #3455 fix refs missing on empty component root
• #3468 ensure v-model changes take effect before v-on listeners
• #3472 fix incorrect name option warning
• #3474 fix transition insert hook duplicate invocation on slot nodes
• #3478 fix v-on with chained key modifiers
• #3484 fix v-show should be able to overwrite inline display: none
• #3488 fix v-show transition enter hook when using raw render function / JSX

v2.0.0-rc.2

Improvements

• v-show now respects the original display value of the element (@chrisvfritz)
• The server renderer now supports rendering <script> and <style> tags (they are still forbidden on the client) - this allows using a Vue component to render the HTML layout of the entire page. (@naumovs)
• Added warning for missing v-on handlers.
• Added warning for duplicate <slot> usage which used to work in 1.x but is no longer supported in 2.0.

Fixed

• Fixed vdom patch errors on components with empty root (e.g. when root has v-if or transition)
• #3433 fix enter hook not firing for v-show transition
• #3439 fix v-model on input[type=range] in IE
• #3440 fix out-in transition entering early when parent re-renders
• #3451 fix native events on components with inline-template
• #3453 fix unnecessary child watcher calls on parent re-render

v2.0.0-rc.1

WIP Documentation

Fixed

• prop validation now work when code is run across different vms/iframes.

Breaking Change

• SSR: when using serverCacheKey, the component also needs to have a unique name option.

v2.0.0-beta.8

New

• Improved SSR error handling when using bundleRenderer.renderToStream
• Improved SSR warning when component is missing render function / templates

Breaking Changes

• keep-alive is no longer a special attribute: it is now a wrapper component, similar to <transition>:

  <keep-alive>
    <component :is="view"></component>
  </keep-alive>

  This makes it possible to use keep-alive on multiple conditional children (note the children should eventually evaluate to a single child - any child other than the first one will be ignored):

  <keep-alive>
    <comp-a v-if="a > 1"></comp-a>
    <comp-b v-else></comp-b>
  </keep-alive>

  When used together with <transition>, make sure to nest it inside:

  <transition>
    <keep-alive>
      <component :is="view"></component>
    </keep-alive>
  </transition>

Fixed

• #3395 fix v-show transition triggering more than necessary
• #3400 fix slot resolution on re-renders
• #3403 fix double quote decoding inside attributes when using DOM template
• #3406 fix static node reused incorrectly inside v-for

v2.0.0-beta.7

New

• Improved warning information for SSR hydration failures.
• Support :class and :style binding values when using class and style in v-bind="object".

Fixed

• Fixed SSR hydration failures when using <transition> that evaluates to empty nodes.
• #3379 :style bindings now work for plain strings as well
• #3386 & #3391 slot children not correctly updating

Breaking Changes

• When using render functions, it is now no longer necessary (nor supported) to wrap component children inside a function:

  render (h) {
    // before
    return h(Comp, () => [...children])
  
    // after
    return h(Comp, [...children])
  }

  If you are using JSX, make sure to upgrade to babel-plugin-transform-vue-jsx to ^3.0.0.
