VennDiagram 1.6.7 2014-06-25 (rsun)
---------------------------------------------------------------------------------------------------
BUG FIXES
* correctly handle NULLs passed to draw.pairwise.venn (either directly or through venn.diagram)

VennDiagram 1.6.6 2013-09-05 (malbuquerque)
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* new argument added, 'imagetype', which allows for the specification of the image format (tiff, png or svg)

VennDiagram 1.6.5 2013-08-21 (pboutros)
---------------------------------------------------------------------------------------------------
BUG FIXES
* element a7 not updated after rotations in all special-case ternary drawing functions

VennDiagram 1.6.4 2013-07-10 (pboutros)
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* reduce line-widths of documentation to 90 characters to meet a new CRAN policy (NOT enforced in R v3.0.1, only in R-patched)
* made even more examples \dontrun{} to accommodate CRAN requests

VennDiagram 1.6.3 2013-07-05 (pboutros)
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* bug-fix in draw.010 that was not updating empty overlap regions properly after rotation

VennDiagram 1.6.1 2013-05-20 (jhawley)
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Triple, Quadruple, and Quintuple plots now notify what areas are negative
* bug-fix in draw.022AA00 that was preventing properly scaled diagrams

VennDiagram 1.6.0 2013-04-12 (jhawley)
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Removed 'list.order' as an argument for draw.triple.venn and implicitly mapped ordering for triple and double plots
* Argument ordering no longer matches by sample size, but by order of lists (i-th data elements match with i-th elements in other arguments)
* Added NEWS file to detail updates and fixes
* Changed 'force.unique' to default to TRUE
* circle.R is deprecated because of redundancies (using ellipse.R instead)
* Created and updated documentation for draw.* functions

BUG FIXES
* Fixed ordering and rotation of labels and colours in double and triple Euler plots
* Fixed 'NaN error' within find.dist.R
* Changed output of rotate.sp from a two-element list to a four-element list for easier access to rotated vectors
* Updated documentation to clarify code

VennDiagram 1.5.4 2013-02-14
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Added OICR header notification to all R files
* Looks for Darwin-based machines and uses bitmapType=quartz instead of the default cairo

VennDiagram 1.5.3 2013-01-03
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Added 'inverted' command line parameter and removed it from parameter list (passed as one of 'Details Arguments')
* Removed references to obsolete variable sp.cases from examples (old code still works silently)

VennDiagram 1.5.1 2012-09-02
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Added 'force.unique' argument to venn.diagram to only look at unique elements in list elements (defaults to FALSE)
* Added examples in \dontrun{} to accommodate CRAN request
* Code clean-up for clarity, efficiency, and consistency

VennDiagram 1.4.0 2012-08-08
---------------------------------------------------------------------------------------------------
MAJOR UPDATES
* Able to create quintuple Venn diagrams (very similar to quadruple diagrams; accessible through venn.diagram and draw.quintuple.venn)

MINOR UPDATES
* 'ext.percent' in draw.pairwise.venn now allows for individual manipulation of proportions

VennDiagram 1.3.0 2012-07-03
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Added 'ext.percent' argument in draw.pairwise.venn to allow user-specified proportion under which to trigger external text drawing

VennDiagram 1.2.2 2012-06-18
---------------------------------------------------------------------------------------------------
BUG FIXES
* Fixed NA and error handling

VennDiagram 1.2.0 2012-04-29
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Enabled draw.pairwise to work with expressions
* Documented how to output to screen and updated additional documentation

BUG FIXES
* Fixed an antialiasing issue
* Fixed some special case issues

VennDiagram 1.1.0 2011-09-28
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Ability to have separate category names

VennDiagram 1.0.2 2011-05-15
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Ability to use expression values in titles

VennDiagram 1.0.1 2011-04-18
---------------------------------------------------------------------------------------------------
MINOR UPDATES
* Added 'offset' argument to some three-set Euler diagrams
* Enabled drawing of title and subtitles
* Minor updates to draw.special.case functions
* Minor changes to how 'cat.just' format is correctly determined
* Added ovverrideTriple arguent for specific scaling in triple diagrams

VennDiagram 1.0.0 2010-06-28
---------------------------------------------------------------------------------------------------
MAJOR UPDATES
* Initial release of code, based off of lattice
* Displays single, double, triple, and quadruple Venn and Euler diagrams
* Flexibility of fonts, colours, spacing, and borders
