 We are excited to publish version 2.2.0 of osm2pgsql. This release adds two powerful building blocks that can be used to implement all sorts of new features. The new "Locators" and the "deleted callbacks" featuere seem simple by themselves, but they can be used as basis for many features that have been requested for years.
