+  1. Fixed overriding css variable doesn't work at `0.11.0` (close: [#639](https://github.com/vuejs/vuepress/issues/639))
+  2. Split `override.styl` into two APIs: `override.styl` and `style.styl`, the former will focus on ONLY the stylus constants override, while the latter will focus on styles override or custom styles. See also: https://vuepress.vuejs.org/default-theme-config/#simple-css-override.
