The most prominent change in this release is the addition of a prototype Stanford-parser compatibility mode.
The Stanford parser provides a de facto standard definition of dependency relations used in parsing. Relex has a compatibility mode which attempts to generate the same output as the Stanford parser. This is an interesting thing to do, for two reasons:
1) It provides a way of double-checking parse results,
2) RelEx is nearly four times faster than the Stanford parser.
The compatibility mode is currently in "beta": it is almost fully implemented, but still has a number of rough spots that need work.
