Version 1.0 (March 2010)

Version 1.1 (January 2013)
    - Fonts scale with the size of the plot window, and are embedded in the PDF file. Tip: to produce the best graphical output, maximize your plot window and save as PDF.
    - The program remembers the input directory, thus saving time when processing multiple input files.

Version 1.2 (August 2013)
    - Higher resolution graphics.
    - Ability to save plot in .png format on Mac and Linux.

Version 1.3 (January 2014)
    - Fixes a problem in which some of the contours partially plotted outside the ternary diagram.
    - Age labels on the top of the logratio plot no longer overlap.
    - The input table automatically switches from 7 to 9 columns when Sm is present in (but colour labels are absent from) the input file.
    (update based on feedback from Kalin McDannell).

Version 1.4 (February 2014)
    - Fixed a minor bug caused by the previous upgrade, which in some cases caused the program to stop after drawing the age contours.
    - Ellipse colours are now always taken from the ninth input column unless the latter is empty.

Version 1.5 (March 2014)
    - Automatically checks for updates.

Version 2.0 (September 2014)
    - Ternary plots are scaled by normalising to the geometric mean composition [Von Eynatten et al., 2002].
    - Improved error propagation of individual analyses.
    - Automatic scaling of freshly pasted data.
