Next.js 6.1

What this post added

Next.js 6.1 removes `react-hot-loader` for improved hot reloading reliability and closer parity with production behavior. It introduces automatic `hot-self-accept-loader` application for custom `pageExtensions`. Codebase refactoring includes moving the build directory and renaming `.next/dist` to `.next/server`. A new `next-codemod` tool is released with an initial `url-to-withrouter` codemod to automate migration from the deprecated `url` prop to `withRouter`. Future work on Webpack 4 and serverless Next.js is highlighted.
