* Adjust model loading process to include models in non-standard paths eagerly.

=== 0.4.0:

* Support to optionally display single table inheritance relationships
  (inheritance=true).
* Support to optionally display polymorphic associations (polymorphism=true).
* Adjustments to 'advanced' style so that it matches original Bachman style,

* Ignore models without tables (reported by Mark Chapman).
* Mutual indirect relationships are now combined.
* Changed API for diagram generation.
* Restructured classes and renamed several API properties and methods.
* Added new edge type to describe single table inheritance and polymorphic
  associations: Specialization.
* Added compatibility for Active Record 3.1 (beta), removed dependency on Arel.

* Altered the type descriptions of attributes.
* Renamed options for flexibility and clarity.
* Improved internal logic to determine the cardinality of relationships.
* More versatile API that allows you to inspect relationships and their
  cardinalities.
* Changed line widths to 1.0 to avoid invisible node boundaries with older
  versions of Graphviz (reported by Mike McQuinn).
* Bundled examples based on actual applications.

=== 0.2.0

* Added simple way to create your own type of diagrams with a tiny amount of code.
* Improved internal API and documentation.
* Subtle changes in diagram style.
