Changes in version 1.28                         

    o   removed `ggalt` package dependency by incorporating custom `geom_encircle` function
	directly into EnhancedVolcano as `ggalt` is no longer on CRAN

                        Changes in version 1.12                         

    o   added max.overlaps and min.segment.length to provide further control over
	connectors. max.overlaps replaces maxoverlapsConnectors, but both can still
	be used for legacy purposes

                        Changes in version 1.10                         

    o   added functionality to parse expressions in labels via parseLabels (TRUE/FALSE)

    o   over-rides ggrepel's new default value for max.overlaps via introduction of
	maxoverlapsConnectors = 15

    o   user can now specify a direction for connectors via directionConnectors

    o   removed labhjust and labvjust

    o   added pCutoffCol (via Andrea Grioni)

                         Changes in version 1.8                         

    o   added functionality to encircle variables of interest

    o   added option to remove arrowheads on connectors

    o   added option to rasterise images via ggrastr::geom_point_rast (Benjamin Ostendorf)

    o   changed axis.text.y = element_text(..., vjust = 1.0) to 0.5 (Benjamin Ostendorf)

                         Changes in version 1.6                         

    o   removed legendVisible and pLabellingCutoff parameters

    o   deprecated transcriptPointSize, transcriptLabSize,
	transcriptLabCol, transcriptLabFace,
	transcriptLabhjust, transcriptLabvjust,
	boxedlabels, and drawconnectors parameters

    o   now pad xlim by +/- 1

    o   moved default position of labels to be central to
	its respective point

    o   added 'colGradient', which colours points continuously
	based on p-value

                         Changes in version 1.4                         

    o   modified behaviour where a p-value of 0 is found: now
	converts these to 10^-1 * lowest non-zero p-value

    o   added new paremeter 'legendLabels', which allows user
	to use expressions in the legend label

    o   added support for tibbles

    o   transcriptPointSize, transcriptLabSize, transcriptLabCol,
	transcriptLabFace, transcriptLabhjust, and
	transcriptLabvjust now deprecated. Use pointSize, labSize,
	labCol, labFace, labhjust, and labvjust, respectively,
	instead

    o   pointSize default changed to 2.0

    o   boxedlabels now deprecated. Use boxedLabels

                         Changes in version 1.2                         

    o   added functionality to shade specific genes in the plot space (parameters:
	shade, shadeLabel, shadeAlpha, shadeFill, shadeSize, shadeBins)

    o   added new parameters 'labhjust' and 'labvjust' for fine tuning position of
	labels

    o   suppress warnings about removal of missing values

    o   now easier to hide the legend via legendVisible = TRUE/FALSE

    o   changed 'colOverride' to 'colCustom'

    o   added a new 'shape' parameter to control the shape of plotted points

    o   added a new 'shapeCustom' parameter, akin to functionality supplied by
	'colCustom' (formerly 'colOverride')

    o   added functionality to add title, subtitle, and caption (parameters: title,
	subtitle, caption, titleLabSize, subtitleLabSize, captionLabSize = 12)

    o   added functionality to add extra vertical and horizontal lines (parameters:
	hline, hlineType, hlineCol, hlineWidth, vline, vlineType, vlineCol,
	vlineWidth)

    o   changed 'colConnectors' default from "black" to "grey10"

    o   added extra parameters for line connectors (parameters: typeConnectors,
	endsConnectors, lengthConnectors)

    o   'labhjust' and 'labvjust' are now 'transcriptLabhjust' and
	'transcriptLabvjust', respectively

    o   user can now specify to draw transcript labels as text and text in boxes
	via 'boxedlabels' (TRUE/FALSE)

    o   drawconnectors now deprecated. Use drawConnectors

                        Changes in version 1.0.0                        

    o   user can now supply her/his/its own colour vector to label the points

    o   default is to now draw grid lines and only have left and bottom borders

    o   when selectLab is not NULL, even variables that do not pass the thresholds
	are now labelled along with those that do, even when DrawConnectors is
	either TRUE or FALSE.

    o   correctly catches non-numeric x and / or y variables, and throws error.

    o   the function now tolerates P values of 0 (zero) and replaces these with the
	lowest possible double value, given a user's specific computer architecture
	and R version.
