--- NEW FILE ChangeLog ---
1.04: 2000/6/17, add "load" button to svm-toy. README 
file updated.

2.0: 2000/8, major updates. Include nu-svm, one-class svm, and svr

2.01: 2000/9/22, correct the calculation of obj value and number of bounded support vectors

2.02: 2000/9/29, replace b^2/2 newsvm to regular nu svm.

2.03: 2000/10/24 some improvements on the computational speed

2.1: 2000/12/19 Java version included, regression demonstrated in svm-toy

2.2: 2001/1/16 multi-class classification, nu-SVR, remove epsilon_a

2.3: 2001/3/15 c+-, cross validation, fix some minor bugs

2.31: 2001/4/12 fix one bug on one-class SVM, use float for Cache

2.32: 2001/9/23 
	1. max line number of svm-scale now dynamic
	2. gcc 3.0 problem: now g++ always used
	3. java code in a "libsvm" package
	4. avoid a problem when compiled with Borland C++ builder

2.33: 2001/12/1
	Python interface added

2.34: 2002/6/15
	Add the subroutine svm_check_parameter in svm.cpp
	--> better error handling
	fix bug of python interface for handling different weights
	fix bug of cross validation in svm-train.c

2.35: 2002/6/16
	libsvm.jar was not compiled correctly in 2.34

2.36: 2002/8/4
	grid.py added: contour plot of CV accuracy
	fix several bugs

2.4:  2003/4/1
	svm.cpp
		non-psd kernel using max(...,0) in svm.cpp
	python interface
		python interface bug (nu-svm)
	grid.py
		-log2c and -log2c for grid.py
	        output current best
		coarse grid as default (2)
		ssh for grid.py 
	improvements of scaling 

2.5: 2003/11/13
	subroutines for accessing decision values and number of labels. 
		for svm.cpp, java, and  python interface
	fix bug of svm-scale.c (about -r and -s factors)
	use fscanf but not sscanf in svm-predict.c (faster)
	makefile for windows
	add "using namespace std;" in some .java files
	improve easy.py: output cv rate, error messages printed
		better checking
	better python interface example svm_test.py
	and some minor updates

2.6: 2004/04/01
	Probability estimates for classification/regression 
	Python interface: use swig 1.3 instead of 1.1
	Cross validation becomes a library subroutine
	A few minor corrections: (not completely listed)
		more interface functions such as getting svm_type
		print nu only when Cp=Cn
		floor division in python interface

2.7: 2004/11/10
	Stratified cross validation
	Better faq
	Scaling: support storing the factor of y
	A few minor updates:
		class QMatrix added
		improve the use of easy.py and grid.py on windows 
		grid.py: same CV and same g: use smaller C
		sparse input for python interface
		working set selection: < to <=

2.71: 2004/11/20
	fix a java bug introduced from 2.6 to 2.7

2.8: 2005/04/01
	new working set selection via second order information
	fix minor changes/corrections:
		problem when cache size less than two kernel columns
		-v #data -> stratified CV is not loo -> ensure loo is done
		problem of typing "svm-train -c" only
		problem of "svm-train -n 1 -s 3 ..."
		python interface makefile: -fPIC for 32/64bit
		color change in svmtoy
		makefile in building QT svmtoy

2.81: 2005/11/20
	add a python script subset.py for subsampling
	slightly modify the working set so it's exact the same as the paper
	default cache size to 100 MB

2.82: 2006/04/01
	precomputed kernel
	directly implement a fast powi() function
	poly degree double to int
	minor corrections:
		java code for CV
2.83: 2006/11/17
	Fix the bug of -t 3
	better checking load/save in svm-train.c/svm-predict.c/svm.cpp
	remove redundant var pos in svm_predict_values (thanks to Albert Strasheim)
	Better descriptions in README for the precomputed kernel

2.84: 2007/04/01
	Improve the shrinking code: faster for some cases
