+* The main data flow and taint tracking APIs have been changed. The old APIs
+  remain in place for now and translate to the new through a
+  backwards-compatible wrapper. If multiple configurations are in scope
+  simultaneously, then this may affect results slightly. The new API is quite
+  similar to the old, but makes use of a configuration module instead of a
+  configuration class.
