    running serially on many small files.
  * A new python interface to the internal `prepfold` folding code
-   (`simplefold`).

  * Many bug fixes and minor improvements, including one that would cause
    segfaults with very large dispersion sweeps in `prepdata` and `prepsubband`,
    and a problem with `prepfold` significance calculations.
