BREAKING CHANGE: Users will have to explicitly list their required ESLint version in the project's package.json. The major concern behind this change is that ESLint release schedule is never aligned with Vue CLI's. See https://eslint.org/blog/2019/04/eslint-v6.0.0-alpha.0-released So even if we upgraded our built-in ESLint version to v5, we'll see a new major release of ESLint in the coming months. Meanwhile we can't easily upgrade the built-in ESLint version again without bumping our major version number. This could become a maintenance nightmare.
