0.24.0

• Improved type annotations for UserList subclasses. (#299)
• Macro definitions gained a new commented_out property indicating that a macro definition is commented out. Another new property, comment_out_style, determines if it is achieved by using a %dnl (discard next line) directive (e.g. %dnl %global prerelease beta2) or by replacing the starting % with # (e.g. #global prerelease beta2).
