* New since libbow version 0.9New classification methods have been added:  maxent, svm, active,nbshrinkage. New libbow front-ends have been released:  crossbow (documentclustering), archer (AltaVista-style document retrieval).Many bug fixes.* New since libbow version 0.8.The command-line arguments for setting test-train splits havechanged.  The -p option has been removed.  There are new options--test-set and --train-set.In the absence of any test-train split command-line options,previously the default test-train split was 30% testing, 70% training.Now the new default is 0% test, 100% train.  Thus, you must specifysome test-train split on the command-line for non-diagnosticclassification runs, such as runs with --test option.The --split-seed option has been renamed to --random-seed.Changed "infogain-vector" to "print-word-infogain".  Changed "infogain-pair-vector" to "print-word-pair-infogain".  Changed "weight-vector" to "print-word-weights".  Changed "foilgain-vector" to "print-word-foilgain".* New since libbow version 0.6.The library and its front-ends now take GNU-style long-options.  Forexample, to see the new rainbow options, execute "./rainbow --help".NOTE: Several of the options have changed.  For example, `-R' shouldbe replaced with `-O'.  WARNING: One of the options as reversed meaning!  Pre-version-0.7,stemming was on by default; `-S' turned it off; now, stemming isturned off by default; `-S' will turn it on.WARNING: The data file format for models have changed.  You will haveto re-build any rainbow or arrow models you created with libbowversion 0.6.  Otherwise rainbow or arrow will crash when reading inthe old models.
