Composer不安装最新的Laravel（5.0.15）

Question

Latest stable version of Laravel is 5.0.15 but when I run

composer install laravel/laravel :

It says:

Installing laravel/laravel (v5.0.1)
  - Installing laravel/laravel (v5.0.1)
    Downloading: 100%

I've run composer clear-cache but same version is downloaded.

How can I force composer to install latest stable version.

Contents of composer.json:

"require": {
    "laravel/framework": "5.0.*"
},
