Release Notes: Minimum edit distance functionality has been added to the API so that one can search for the closest approximate match in an automaton. There's new faster transducer/automaton apply code, as well as optional indexing of arcs in the separate flookup utility. This release adds rewrite rule formalism "transducers with backreferences" (e.g., T -> || L _ R, where T is a transducer). The flookup-utility now has option to run as a UDP server (-S). More low-level functions have been added to support faster construction of complex automata. There are minor bugfixes in the apply code and some rare memory leak fixes throughout.
