7.4.0

New rules

• react/no-typos: Prevents common typos on React components
• react/no-unused-state: Prevent definition of unused state fields (currently missing docs)

Changes

• ESLint 4.5 is now required: npm i -D eslint@^4.5 to upgrade your version
• eslint-plugin-react was upgraded. If you get warnings about unknown rules, just drop your node_modules and install all deps again.
• Added new ruleset for Node.js 8.3 release: environments/nodejs/v8-3: This ruleset enables object rest-spread syntax introduced in v8 engine 6.0
• For files in config/ or configuration/ directories, the rule no-process-env has been turned off
• For files matching patterns test/**, packages/*/test/**/*.test.*, packages/*/test/**/*.spec.*, the mocha: true environment is enabled and func-names rule is turned off

  These settings were previously usually configured on a custom, per-project .eslintrc.js. ESLint introduced an option to override some rules based on matching path patterns so these rules can now be centrally overridden.
