Changed paths:

The variable holding the reference to the Thread used to perform filtering was not transient - fixed.

Changed paths:

The -O option now actually works - this was not implemented before :-) Furthermore, the Reader/Writer for IO of cluster center files are now closed properly after use and marked as transient (thus fixing not serializable exceptions).

Changed the default output to be System.out instead of a StringWriter. This allows large datasets to be produced incrementally via redirection (rather than having to use -o) in the console and SimpleCLI.

Fixed a bug where cluster nominal attribute value counts were not getting set properly when empty clusters were pruned. Only affected the case when empty clusters occurred and the user had opted to output standard deviations/frequency counts.

Class attributes that are date attributes need to be treated the same way as classes that are numeric attributes... Behaviour of default methods for classifyInstance() and distributionForInstance() were previously broken for class attributes that were date attributes (they simply returned a missing value.)

From Eibe: Fixed problem where unprune() step caused root node to not be labeled a leaf when it really is a leaf. This only caused problems when unpruned tree consists of a single node that is a leaf node.

Changed paths:

From Eibe:AttributeLocator now uses BitSet and ArrayList rather than Vector. In particular, BitSet is used instead of Vector<Byte>, resulting in *HUGE* space savings when using filters to process/produce large-dimensional datasets! Also removed occurrences of DenseInstance in error messages originating in AbstractInstance. Finally, improved efficiency of insertAttributeAt() and deleteAttributeAt() in Instances and added new method replaceAttributeAtt(), replacing almost all calls of insertAttributeAt()/deleteAttributeAt() in WEKA with calls of replaceAttributeAt().

Added missing values as a capability (since the replace missing values filter is applied internally by default). Now pre-processes nominal attributes with the unsupervised nominal to binary filter.
