* all plot functions: 
  + allow user to set plot margins

* Calculation and visualization functions have been separated
* Added support for handling unphased haplotypes and unpolarized markers
* Output in form of matrices has been replaced by data frames
* Simplified column names in data output (use only capital letters and underscores)
* Improved visualization of furcation trees
* Added visualization of shared haplotype lengths
* Added simple function to delineate candidate regions of selection
* Added options to yield virtually identical results with program hapbin
* Made all plots more customizable
* Added new vignette with in-depth discussion of example files
* Disagreement between code and vignette about uni-lateral p-value for Rsb/XP-EHH has been cleared

### rehh 2.0.4 (February 13, 2019)

* Corrected implementation of maxgap in combination with discard_integration_at_border=FALSE
* Added parameter scalegap
* Included section about gaps in vignette, added details in comparison with hapbin, corrected rendering

### rehh 2.0.3 (June 12, 2017)

* Bug corrected in the ihh2ihsplot (it lead to a crash when the freqbin argument was set to 0)
* Inactivation of graphical display in multiple windows (i.e., plot.new calls) in the calc_ehh, calc_ehhs, ihsplot, rsbplot, xpehhplot and distribplot functions
* Minor corrections in the manual pages

### rehh 2.0.2 (November 15, 2016)

* Option maxgap modified (functions return NA value if not satisfied)
* Example data sets removed from the rehh package and included in the newly developed rehh.data package. The function make.example.files() was modified accordingly.

### rehh 2.0.1 (October 24, 2016)

* Option maxgap added to the calc_ehh, calc_ehhs and scan_hh functions

### rehh 2.0.0 (July 30, 2016)

* Major modification of the algorithm to explore haplotype variability (more than one order of magnitude faster), including parallelization
* Major modification of the data2haplohh function to improve reading efficiency and allele recoding. In addition, a new input data file format (haplotype.in.columns) is now available
* Computation of xp-EHH
* A vignette that details how to use the package is now included in the package
* Several other minor modifications in other functions

### rehh 1.13 (May 13, 2015)
