Changes from 1.2 to 2.0
***********************

03-04-2005

	- upgrade LIBSVM to version 2.71

03-13-2005

	- add Pearson correlation as feature selection criterion

03-13-2005

	- remove clustering. There are better programs for clustering
	elsewhere.

03-13-2005

	- remove distance selection menu.

03-15-2005

	- support individual class costs for C-SVM learning

03-17-2005

	- eliminate FORTRAN code

03-28-2005

	- add Model Selection menu for Support Vector Machine algorithm

04-19-2005

	- add forward selection and backward elimination feature subset
	selection algorithms
	
04-19-2005

	- add inter-intra distance, 1-NN error rate and Bayes error rate
	as criteria for feature selection
	
06-15-2005

	- use GNU autoconf to build PCP

	
Changes from 2.0 to 2.1
***********************
	
07-13-2005

	- use -O3 flags and dynamic building in the distributed Makefiles
	
08-09-2005

	- SVM model selection now automatically creates the prediction
	file pcp.rcl
	
08-10-2005

	- handle empty classes in the test set for named data format
	
08-11-2005

	- create prediction file pcp.rcl for MLP prediction

09-02-2005

	- implement MLP model selection. Rename model selection file
	pcp.svp to pcp.msl.

09-03-2005

	- implement k-NN model selection

11-18-2005

	- add additional information in class prediction file pcp.rcl
	(correct classification flag, TP, FN, FP, TN flags for two-class
	case)

11-22-2005

	- remove major memory handling defect in forward selection
	algorithm, leading to poor (computational) performance of model
	selection involving forward selection
	
11-25-2005

	- enforce the feasible region for nu in NU-SVM
	
02-02-2006

	- change default number of cross-validation experiments from 10 to
	1
	

Changes from 2.1 to 2.2
***********************
	
02-12-2006

	- support model selection for linear SVM kernel
	
04-17-2006

	- introduce an option to build SVD transform using training+test
	datasets (as opposed to just training data)

05-09-2006

	- report p-error in SVM model selection

05-21-2006

	- simplify build process
