v2.8.3

• camel-case-local-functions: whitelisted primitive builtins to allow coercion, e.g. Number('42') or Boolean(0)
• react-lifecycle-order: now only checks for method ordering in classes extending React.Component, React.PureComponent, Component, or PureComponent
• class-method-newlines, declare-class-methods-after-use: arrow function properties are now treated as methods
• declare-class-methods-after-use: method declaration now only needs to come after first use, not all uses
