Vue warn after vue-template-compiler update to 2.1.1

[Nikolay (Mykola) Nesov]

Hi,

I am using laravel-elixir-vue-2 and after running npm update, I am getting this error on website, though it compiles code successfully.

vue.js?3de6:515 [Vue warn]: Property or method "_leaving" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option. 
(found in component <transition>)

Current version of vue-template-compiler is 2.1.1

In dependencies I have:

"gulp": "^3.9.1",
"laravel-echo": "^1.0.1",
"laravel-elixir": "^6.0.0-11",
"laravel-elixir-vue-2": "^0.2.0",
 "laravel-elixir-webpack-official": "^1.0.2",

...
