1.4.1 (2011-01-27)
  * 'venkatraman''s test for unpaired ROC curves
  
1.4 (2011-01-21)
  * 'smooth' does not apply on 'ordered' factors anymore
  * Can choose how 'best' thresold is determined ('best.method' and 'best.weights' in 'coords' and 'print.thres.best.method' and 'print.thres.best.weights' in 'plot.roc')
  * Minor improvements in the documentation and 'citation'
  * 'print' now prints the response instead of "response" and more informative data in 'htest's
  * Bootstrap with 'ci.auc' consumes much less memory
  * Unpaired bootstrap and DeLong's test
  * Specificity and sensitivity tests (in 'roc.test')

1.3.2 (2010-08-24)
  * 'print.auc' printed incorrect CI in 'plot.roc' (thanks to Alexander B. Leichtle for the report)
  * failed to detect local maximas in 'coords' when 2 or less points were selected
  * don't consider ROC extremities (+-Inf at 1.0/0.0 SE<->SP) as local maximas
  * Sensitivity and specificity were inverted in coords when results were reported as list.
  * CI is not re-computed by default in 'smooth.roc'. You can still turn it on with 'reuse.ci=TRUE'
  * New function 'are.paired'
  * Local maximas could be incorrectly detected in 'coords' (and 'plot.roc') with 'predictor's containing more than 2 levels.
  * New method 'venkatraman' for 'roc.test'

1.2.1 (2010-05-11)
  * Added DeLong method in 'ci.auc' with GUI
  * Return value of 'ci.auc' does not contain an 'aucs' item anymore.
  * Put most examples with bootstrap within '\dontrun{}' blocks for faster (but less useful) checks execution
  * Added 'auc.polygon.*' and 'max.auc.polygon.*' arguments for 'polygon' in 'plot.roc'

1.1 (2010-05-05)
  * Added 'lines.roc' functions for ROC
  * Added 'type' argument for both 'lines.roc' and 'plot.roc'
  * Added 'print.auc.col' argument to 'plot.roc'
  * Fixed a warning in 'roc.test.default' when the class of 'predictor1' had several elements

1.0 (2010-04-26)
  * First public release
