Version 1.93 released on January 27, 2013. We fixed some minor issues in this version.
An experimental version using 64-bit int is in LIBSVM tools. It in theory can handle up to 2^64 instances/features if memory is enough.
We are interested in large sparse regression data. Please let use know if you have some. Thank you.
A practical guide to LIBLINEAR is now available in the end of
Some extensions of LIBLINEAR are at LIBSVM Tools.
LIBLINEAR is the winner of ICML 2008 large-scale learning challenge (linear SVM track). It is also used for winning KDD Cup 2010.
LIBLINEAR is a linear classifier for data with millions of instances and features. It supports
Main features of LIBLINEAR include

See Appendix C of our SVM guide about using other solvers in LIBLINEAR.
Warning:If you are a beginner and your data sets are not large, you should consider LIBSVM first.
The package includes the source code in C/C++. A README file with detailed explanation is provided. For MS Windows users, there is a subdirectory in the zip file containing binary executable files.
