      Version 7 is not ready for beta yet but an advance notice of changes
      may be useful.

      Most changes are related to performance.

      Previous performance improvements in versions 2 to 6 have been
      consolidated into common methods. The best example of this is that all
      progressive array indexing has been replaced by link lists. Almost all
      fixed arrays are replaced by extendable double link lists.

      Learning performance has been improved by propagating the square error
      rather that the absolute error. This usually results in many local
      minima that stop learning. The progress direction is guided and
      potential local minima are usually avoided. Even if they can't be
      avoided a back off is built in.

      Performance of Edit > Replace values on large grids is improved by a
      huge amount.

      Performance of Edit > Replace row and column names is also improved.

      Edit > Copy Example Rows on large grids is much faster.

      Tools > Extend Learning is about 100 times faster.

      Query > Query > Seek cycle is faster.

      The default target error has been changed to 0.01

      The minimum cycle count has been removed.

      The problems with the dialog title in Edit > Replace has been fixed.

      The problems with Edit > Replace row and column names have been fixed.

      If any other problems are lurking please let me know.
