VueJs 2.0 - how to listen for `props` changes

In the VueJs 2.0 docs I can't find any hooks that would listen on props changes.

Does VueJs have such hooks like onPropsUpdated() or similar?

Update

As @wostex suggested, I tried to watch my property but nothing changed. Then I realized that I've got a special case:

<template>
    <child :my-prop="myProp"></child>
</template>
<script>

export default {

props: [‘myProp’]

}

</script>

I am passing myProp that the parent component receives to the child component. Then the watch: {myProp: …} is not working.
