Get version 18 from the usual place.
Now also fixed a bug where doubly polymorphic parents weren’t being strict about which children they returned (thanks to Xardion and Agile for the discovery).
- now supports legacy primary key names (thanks Paul Wright)
- fixes a bug related to instantiating attributes of namespaced models
- fixes a bug that prevented doubly-polymorphic children from accessing their parents sometimes
- fixes a very obscure bug when running on sqlite3 (specifically, this)
Now it has no more bugs. You may uncross your fingers. Thanks goes to Hildolfur for putting the plugin through the wringer and revealing the last three problems.
