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)

2.84: 2007/04/01
Improve the shrinking code: faster for some cases
Code more 64-bit friendly: allow large -m
In Solver, b is replaced by p
Subroutine max_violating_pair removed. Things are directly
written in do_shrinking().
Modify do_shrinking() so variable names are the same as libsvm
