3.0.0

Changes from rc.2

• Add forwardRef as a valid component definition (#311)
• Resolve flow $Keys to union when typeParameter is an ObjectTypeAnnotation (#290)
• Attempt to support system-components (#292)
• Add support for PropTypes.exact
• resolve Object.values() in PropType.oneOf() (#318)

Big Changes from 2.x

• Drop support for node 4. Only node 6 and newer are supported
• Switched the internal parser from babylon@5 to @babel/parser@7. This should not break anything, but will support a lot more newer javascript syntax features as well as newer flow syntaxes.
• react-docgen now parses only the new decorators proposal syntax and not the old one anymore by default. You can switch back to the legacy decorators proposal with the cli flag --legacy-decorators or the programmatic options { legacyDecorators: true } passed as 4th parameter to ReactDocgen.parse().
• The types of method params and return (parsed from JSdoc) are now the same as the flow types.
