v1.0.18

New

• Due to security concerns, the devtools hooks are now disabled in production builds by default. However, you can explicitly enable it by setting:

  Vue.config.devtools = true

• Vue's internal observation mechanism has been improved to allow you to take advantage of data that are supposed to be immutable. A common use case is when you are simply replacing a huge data structure that you know will never be mutated with a fresh copy. You can now freeze it with Object.freeze and Vue will skip the getter/setter conversion (including its nested values) for that object.

  As a reference, in the DBMonster benchmark, simply freezing the data results in 50%+ FPS increase.

• Decent performance improvement (~15%) to watcher's dependency collection process.
