Stable production version

Mordecai has been in production use in several settings for over a year. This release reflects the stable version that has been in use. It has several known bugs (see open and closed issues), but is stable overall. If you have an existing application that relies on Mordecai's previous idiosyncrasies, use this version. The master branch of Mordecai will begin to change with new features and improvements to its core geocoding functionality.
