	* Version 1.5.4 released

2014-02-20

	*  Version 1.5.3 released.

2013-12-07

	*  survival listed only in Enhances rather than Suggests, fixing
	package check NOTE.

2013-02-11

	*  Added arguments "tcol" and "mcol" to denstrip to change the
	colours of tick marks.

2012-04-02

	*  .filled.contour replaces .Internal call in densregion.  The
	package therefore now depends on R 2.15 or later.

	*  Default value of 1 added to "max" argument in denstrip.legend,
	fixing the problem revealed by R-devel.

	*  Version 1.5.2 released

2011-07-25

	*  Fix for densregion with very small numbers of unique densities.
	Thanks to Daniel Chainey for the report.

2011-01-17

	*  Fix for error in NAMESPACE which caused CHECK fail.

	*  Version 1.5.1 released

2010-05-18

	*  Version 1.5 released

2010-05-06

	*  Added "colmin" argument to all functions which accept "colmax",
	If set to "transparent", allows overlapping strips and regions to
	merge smoothly, on all devices which support transparency. Thanks
	to Anne Presanis for the suggestion.

2009-10-07

	*  Accept data frames as well as matrices in cistrip(), as long as
	all entries are numeric.

2009-09-24

	*  Version 1.4 released

2009-09-17

	*  x and y limits in lattice plots taken from
	current.panel.limits() instead of trellis.last.object(), so
	that it works when one axis shows factor levels.  Example
	of use of denstrip with "bwplot" added to help(denstrip).
	Thanks to Kevin Wright for the suggestion.

2009-03-23

	*  Examples using "Surv" changed for compatibility with new
	survival package in upcoming R 2.9.0.

	*  New argument "contour" to densregion.default to show contour
	lines of constant density value.

	*  Version 1.3 released

2008-11-07

	*  cistrip now allows different "pch" for each element in a vector
	of strips.  Similarly, the point sizes can be varied with a "cex"
	argument.

2008-11-03

	*  References updated to published version of the paper.

	*  Version 1.2 released.

2008-09-09

	*  Code of the form seq(0, 1, length=n+2)[-c(1,n+2)] replaced by
	ppoints(n, a=0)

2008-08-28

	*  Panel functions for all strips implemented for use with lattice
	graphics. Thanks to Austin Frank for the suggestion.

	*  Sectioned density plots can now point downwards or rightwards.

	*  Border drawn around lightest box in sectioned density plot.

	*  cex property added to denstrip.legend.

	*  User-specified axis ticks supported in denstrip.legend.

	*  default axis tick annotations in denstrip.legend now have 3
	significant figures instead of 2 decimal places.

2008-08-21

	*  Version 1.1 released

2008-08-19

	*  Eliminated dependency on R.utils by re-implementing
	seqToIntervals function in sectioned.density(). Thanks to Tobias
	Verbeke for the suggestion.

2008-08-15

	*  alpha channel supported in all user-specified colors.

2008-08-15

	*  Version 1.0 released.
