Changes in version 2.3.3 (2025-08-25)                  

    o   bugfix for new ggplot2 release, thanks @teunbrand

    o   Fix cross references

                        Changes in version 2.3.2                        

Bug fixes and improvements: 

    o   Improvements to calc_auc, works for multiple layers and when the data are passed directly to geom_roc (thanks @collinn)

                 Changes in version 2.3.1 (2023-10-06)                  

Bug fixes

    o   Get rid of warnings about aesthetics (thanks to @mjakubczak)

    o   Fix plotROC-package documentation

                 Changes in version 2.3.0 (2022-05-26)                  

New feature: 

    o   calc_auc returns informative value labels for the panels and/or groups (fixes #74)

                        Changes in version 2.2.2                        

Bug fixes: 

    o   calc_auc when roc is not the first layer (fixes #70)

                 Changes in version 2.2.1 (2018-06-23)                  

Bug fixes: 

    o   Quosure fixes to be compatible with upcoming ggplot2 release. 

    o   Don't plot points in legend when no labels present (fixes #61)

                 Changes in version 2.2.0 (2017-08-09)                  

New features

    o   new cutoff.labels parameter to allow user-supplied labels for the cutoffs (thanks @rcorty)

    o   new increasing parameter with default value TRUE. This determines whether the probability 
	 of a D = 1 increases with increasing M, if FALSE, assumes that the probability increases with 
	 decreasing M (for example if M is the p-value from a regression model) 

Bug fixes: 

    o   Now shows shape aesthetic in legend if mapped. 

                        Changes in version 2.1.0                        

New feature

    o   cutoffs.at argument to geom_roc overrides n.cuts and plots points/labels at user-supplied cutoffs. 

    o   max.num.points argument to stat_roc (can also pass it to geom_roc()) limits the number of points that get plotted.
	   Note this downsamples the curve at the end of the computation, so the benefit of having a lot of data (very 
	   precise curve) is still realized. Thanks @rcorty

                        Changes in version 2.0.3

                        Changes in version 2.0.2                        

Fixes

    o   Bug fix for logical vectors passed to verify_d

                 Changes in version 2.0.1 (2016-02-05)                  

Bug fixes

    o   Style and format of labels/lines fixed, now passed correctly to ggplot functions

    o   Reduce run time of examples

    o   Tested with dev version of ggplot2

                 Changes in version 2.0.0 (2015-12-22)                  

Major changes to the API this release

    o   calculate_roc and ggroc are deprecated

    o   estimate and display roc curves using geom_roc

    o   estimate and display confidence regions using geom_rocci

    o   support for faceting and grouping

    o   better performance and improved interactivity. 

                 Changes in version 1.3.3 (2015-03-16)                  

    o   Added support to ggroc method for objects as returned by ROCR::performance

    o   Bug fix in labeling

    o   Update d3

    o   option to omit inclusion of d3 code

                        Changes in version 1.3.2                        

Added support for new aesthetic options in plot_journal_roc and export_interactive_roc

    o   colors

    o   legends

    o   line type

    o   line width
