This release has a rewrite of the Neural Network code. The old code didn't do pre processing of data and so the networks would get saturated for some data sets. The new code normalizes the data sets and so doesn't have this problem.
The release also includes an implementation of Online DFS (Thanks Ciaran!). Carl Anderson, Senior Scientist at ArchimedesModel.com requested that heuristic functions return doubles instead of int. This is an excellent idea so that's done as well.
The next release scheduled for 28th Feb, will have code for planning (chapters 11 and 12 + bits of chapter 9) + whatever else we feel like working on!
