• Changed
  • Computed Properties should now be provided using the computed option.
  • when a binding's key is not found on a ViewModel and any of its parents, the binding will be now created on the current vm instead of root vm.
  • update() is now optional when creating custom directives.
• Fixed
  • Composition Events will now always cause v-model to lock update.
• Other
  • Internal refactor for binding logic

• Fixed
  • expressions on repeated items now have correct execution context.
  • inline partials now work correctly with directives that require access to parentNode (v-repeat & v-if)

• New
  • new directive: v-with, which can be used in combination with v-component or standalone
• Changed
  • v-component now takes only a string value (the component id)
  • Vue.component() now also registers the component id to be usable as a custom element

• Changed
  • v-style and v-visible have been removed because the user can simply interpolate the attributes.
• Fixed
  • fixed issue in Expression Parser when strings in expressions can contain variable names

• New
  • add support for interpolating bindings in HTML attributes.
• Changes
  • vm.$watch now fires callbacks asynchronously, after all bindings updates have been called.
  • vm.$emit now triggers callback on self only - propagating events should use vm.$dispatch
• Fixed
  • resolve v-model Input Method composition issues when it's piped through filters.

• avoid duplicate Observer.convert() because of the new compile procedure.

Now all binding updates are pushed into a queue and updated asynchronously. This avoids duplicate updates of the same binding when values change multiple times inside a single event loop. In general this brings considerable performance improvement (~40% in the todomvc benchmark).

• API change: scope option is now split into data and methods. proto option has been removed.

• Object observer rewrite: the ViewModel will now directly proxy the value get/set to the data object passed in at instantiation. This allows the user to manipulate data directly or on the ViewModel and they will always be in sync.

• The new observe mechanism makes the v-repeat and v-component much simpler, as a nested object is no longer needed when creating child ViewModels:

  Before

  <div v-component="list:listOptions">
   <div v-repeat="item:model.items">
   {{item.title}}
   </div>
  </div>

  After

  <div v-component="list:listOptions">
   <div v-repeat="items">
   {{title}}
   </div>
  </div>

• rename the library to VueJS
• default directive prefix is now "v-"
• add ability to create custom elements with Vue.element()
• more robust directive parsing and expression parsing
• now user can use the Math object within expressions
