3. Porting from 1.3 or 1.3.1 to 1.4

• The Arguments protocol has moved from the objectbase library to the defobj library. If you were subclassing from the Arguments class you will now need to subclass from Arguments_c and import the defobj.h header file.

• The ListShuffler class has been moved from simtools to collections. You must now import collections.h. Alternatively you can use the new [beginPermuted: aZone] index creation method on a collection from the Collection protocol in place of the ListShuffler protocol.

• The -setLabels:: and -setColors:: methods in the Histogram protocol now each must be given a new count: (unsigned)labelCount and count: (unsigned)colorCount argument, respectively. So, for example, the code formerly in MarketObserverSwarm.m in the market application was:

  [useHisto setLabels: pred]; [useHisto setColors: predictorColors];

  is now changed to:

  [useHisto setLabels: pred count: numPredictorsToShow]; [useHisto setColors: predictorColors count: numPredictorsToShow];
