Vue.js 0.12.0 RC2 发布，此版本更新内容如下：
Support staggering transitions for v-repeat. demo
Simply add a stagger attribute
Support expressions in content selectors. (resolved only once)
v-class can now accept an object value. The keys will be used as class names and toggled based on the truthy-ness of the value.
Warnings in debug mode now prints the error stack instead of invoking the debugger statement.
其他重要改进
When v-ref is used together with v-repeat, and the value being repeated on is an Object, the corresponding ref will also be an Object, with its keys pointing to the associated child instances.
Transition cancel hook: you can now use enterCancelled and leaveCancelled hooks to handle a cancelled transition. Functions returned in enter and leave hooks are no longer respected.
