| Fixes plotting option palette. It now accepts expressions that can be converted into real numbers and a more careful check is done of the values given to that option. Also, more comments in plot.lisp trying to make it more readable. |

| Fixes a bug reported on the mailing list on 2023/11/26 The plotdf sliders were hidden by the coordinates box. To avoid that bug, the sliders have been moved to the right; they will still have to be moved down because the may hide the x axis label. |

| Includes Xmaxima in the applications menu of the desktop manager. In order for an XDG desktop manager to show Xmaxima among the available applications, the icon should go into an icons subdirectory of share, rather than a "pixmaps" subdirectory, and the name of the desktop menu entry file should match the name of the application. |

| Brings back rungeKutta, rungeKuttaA and adamsMoulton functions. These functions are now compatible with the newest version of plotdf. There is no need for rk4.tcl which became equivalent to rungeKutta and the default integration method is now adamMoulton. |

| Uses fixed time steps in the Runge-Kutta method of plotdf. Trying to guess a time step that will lead to a desired displacement in the phase plane has proven to work badly. This commit changes the integration method defined in rk4.tcl into a regular fourth-order Runge-Kutta method. It also introduces some changes to make it feasible to use the alternative methods of adapative-step Runge-Kutta and Adams-Moulton, which will be made in a separate commit. |

| Introduces line clipping in Xmaxima plot2d Examples: plot2d(x-floor(x),[x,0,5], [y,0,.5],[plot_format,xmaxima]); d:[discrete,[[-0.1,1],[1,2.1],[2.1,1],[1,-0.1],[-0.1,1]]]$ plot2d(d,[x,0,2],[y,0,2],[plot_format,xmaxima]); |

| A better fix for bug #4263 This commit reverts some of the changes of commit [210a27] to get a solution that will work in other cases and not just in the example given in that bug report. Currently, Maxima delegates the clipping of points and lines to the external graphic programs. Xmaxima should be modified to do that clipping and Gnuplot should be further investigated because it seems to me that its clipping algorithm fails in some cases. For example compare the following two plots: d:[discrete,[[-0.1,1],[1,2.1],[2.1,1],[1,-0.1],[-0.1,1]]]$ plot2d(d,[x,0,2],[y,0,2],[plot_format,gnuplot]); plot2d(d,[x,0,2],[y,0,2],[plot_format,xmaxima]); |

| Changes the default values for plotting option sample By using a prime number (47) for the sample grid, many bugs of the implicit plots algorithm, such as #3849 and #4198, will remain hidden from ocasional users while I work on solving them which will take some time :) |
