New module DataFlow, which performs a forward data flow analysis over a directed graph. (Such a computation could previously be performed by using the generic solver Fix.Make, but it was somewhat awkward to write, as it required access to predecessors. The new algorithm is easier to use and is more efficient.)
In Memoize, new combinator curried, which can be used in combination with fix or defensive_fix. Thus, for instance, curried fix is a fixed point combinator that constructs a memoizing two-argument curried function.

In Gensym, new abstract type generator, with three functions generator, fresh, and current.
In Memoize, new function visibly_memoize, which not only returns a memoized function, but also provides outside access to the memoization table.
New signatures ONGOING_NUMBERING and TWO_PHASE_NUMBERING and new module Numbering, which provides facilities for numbering things.
Breaking change: the module Fix.Number is renamed Fix.GraphNumbering.
2018/12/06
New release, including new modules (Gensym, Memoize, Tabulate, Number, HashCons, Prop, Glue), new convenience functors (Fix.ForHashedType, etc.), and new demos. The least-fixed-point computation algorithm is unchanged.
2013/06/11
Initial release of the package, containing just Fix.Make, the least-fixed-point computation algorithm.
