Changes in version 1.11.3:

    o   Add hethom method to calculate heterozygosity / non-reference
	 homozygosity in one step

    o   Add countSingletons method

Changes in version 1.11.1:

    o   Add variantData slot to SeqVarData class

Changes in version 1.9.11:

    o   Add Firth test option to regression

    o   Bug fix for refFracPlot: hets significantly different from 0.5
	 plotted as triangles, median line shown

Changes in version 1.9.10:

    o   duplicateDiscordance across two GDS files can calculate discordance
	 based on heterozygote/homozygote status instead of genotype

Changes in version 1.9.9:

    o   duplicateDiscordance across two GDS files can match on either
	 position or position and alleles, with the ability to recode
	 genotypes if th reference allele in one dataset is the alternate
	 allele in the other dataset

Changes in version 1.9.8:

    o   duplicateDiscordance and alternateAlleleDetection require SeqVarData
	 objects; both can match on a subject.id instead of sample.id

Changes in version 1.9.4:

    o   alleleDosage returns list with dosage of each allele separately

Changes in version 1.9.2:

    o   added by.variant option to duplicateDiscordance for two gds files

Changes in version 1.7.9:

    o   added more options to return dosage of different alleles

Changes in version 1.7.7:

    o   added methods to calculate and plot reference allele fraction

Changes in version 1.7.6:

    o   HWE method returns additional columns and allows permutation of
	 genotypes

Changes in version 1.7.5:

    o   Added SeqVarData class to combine sample annotation with GDS object

Changes in version 1.7.4:

    o   HWE works on biallelic INDELs as well as SNVs

Changes in version 1.7.3:

    o   Add methods for duplicateDiscordance with two datasets

    o   Add alternateAlleleDetection

Changes in version 1.5.1:

    o   Use existing isSNV generic from VariantAnnotation instead of
	 redefining

    o   Use BiocStyle for vignette
