Unreleased (`master`)

Drop official support for Ruby 2.3 and below, though these versions may continue to work.

0.1.3

Fix an issue where the same attribute name in multiple classes can result in modifying the attribute for unwanted classes [(#14)[#14]]

Note that this change requires using extend again instead of prepend.

Use RuboCop for development; no external changes.

Simplify code to work for both ActiveRecord and generic Ruby classes by using prepend instead of extend [(#12)[#12]]

The initial release! All basic functionality is in here.
