Point release in the M1 series. No codebase format changes.
Fixes #668, an infinite loop if search results include a type name that referred to more than one definition, a name conflict which can occur after merging two namespaces.
Pro tip: If you are upgrading from earlier in the M1 series, and end up in a situation where you have to choose between getting rid of List##List and List##Sequence, get rid of List##List. Sorry about that.
