    Release Notes: The cursor is now positioned at the end of the command line on a command line recall with the up/down arrow keys. Initial indexing for linear interpolation was off by one causing incorrect results in some cases. This is fixed. You can import an image using the "import a drawing" button or the "File->Import" menu item on the Visualization Window, then click the "Digitize" button on the Import Window to be able to digitize coordinates from the image and store the x-y values in vectors.

      Release Notes: The REPLOT command was failing for some cases of XLOGBASE or YLOGBASE > 1. The GRAPH command was failing if autoscaling was on and a linear axis was drawn first, with a large maximum value, and then the logbase was set > 1 and the GRAPH drawn again. Setting the virtual min/max was not working properly when the number of large increments was set to zero. The font names used in PostScript output have been changed to get better results.

        Release Notes: The FIT command was failing when the fit expression was an evaluable text string, e.g., FIT y=EVALUATE(f) or FIT y=1*f, where f is a text string. This has been fixed.

          Release Notes: Several source files were modified to accommodate gcc v4.3, which "cleaned up" some header dependencies.

            Release Notes: More polar plot characteristics were added: POLARAXISANGLE, POLARAXISLINEWIDTH, POLARCLOCKWISE, and POLARCOMPASSLABELS. The GRAPH\POLAR and GRAPH\RADAR commands were modified. GRAPH\RADAR draws a polar plot with POLARAXISANGLE set to 90, POLARCLOCKWISE set to 1, and POLARCOMPASSLABELS set to 1. The help files were updated.

              Release Notes: Polar plots have been added. GRAPH\POLAR now draws a true polar plot. Polar plots have their own set of characteristics, and the help files have been updated with the new information.

                Release Notes: When reading a matrix where the number of columns is not given, extrema was returning 1000 columns, which is obviously wrong. This has been fixed. All help files have been modified to remove extraneous Windows specific stuff and to fix up broken links and incorrect information. Trapezoid rule calculation was added to the INTEGRAL function. The syntax is INTEGRAL(x,y,'TRAPEZOID').

                  Release Notes: You can now pass a script and parameters as command line arguments. This script will be executed immediately. Linux example: $ extrema --script "testIt.pcm 50 90 'some <alpha> string'" will execute the script testIt.pcm with 3 parameters.

                    Release Notes: The Heaviside function has been added. HEAVISIDE(x) = 0.0 for x < 0, 0.5 for x = 0, and 1.0 for x > 0. The dependency on libxml2 has been removed. This release uses wxXmlDocument and wxXmlNode instead. Command, FCN_adev, FCN_mean, FCN_gmean, FCN_rms, FCN_skew, FCN_stdev, FCN_date, FCN_time, CMD_get, CMD_read, CMD_scalar, CMD_set, GRA_axis, ExSpinCtrlD, ExSpinCtrlI, and ExColorCtrl have been modified to comply with the gcc 4.1.x compiler.

                      Release Notes: New context-sensitive options. If you right-click on a graph legend, a form pops up allowing you to modify aspects of the legend, such as position, size, frame color, title color, title font, etc. On Linux, a command line beginning with the % character will be interpreted as a system command, e.g., %ls. The output from the command is displayed in the terminal window.
