[705] Why vue version is 2.2.x in nuxt/0.10.7 ?

I checked vue "~2.3.x" was built in nuxt/v0.10.7

But If I install 0.10.7, nuxt has vue "~2.2.6". This is node_modules/nuxt/package.json.

{
  "name": "nuxt",
  "version": "0.10.7",
  "description": "A minimalistic framework for server-rendered Vue.js applications (inspired by Next.js)",
  "contributors": [
    {
      "name": "Sebastien Chopin"
    },
    {
      "name": "Alexandre Chopin"
    }
  ],
  ...
  ...
  "dependencies": {
    ...
    ...
    "vue": "~2.2.6",
    "vue-loader": "^11.3.4",
    "vue-meta": "^0.5.6",
    "vue-router": "^2.4.0",
    "vue-server-renderer": "~2.2.6",
    "vue-ssr-html-stream": "^2.2.0",
    "vue-ssr-webpack-plugin": "^3.0.0",
    "vue-template-compiler": "~2.2.6",
    "vuex": "^2.3.0",
    "webpack": "^2.4.1",
    "webpack-bundle-analyzer": "^2.4.0",
    "webpack-dev-middleware": "^1.10.1",
    "webpack-hot-middleware": "^2.18.0"
  },
  ...
}

I tried to install both yarn (no cached) and npm but vue version is still 2.2.6. You can see this if just npm install nuxt
