1 Maxima 5.45-post change log
2 ===========================
6 * Added eval_string_lisp to read in and evaluate lisp forms from a string
7 * Maxima compiled with ABCL can use network connections (option "-s"),
8 which is used by frontends like Xmaxima and wxMaxima.
12 * new additional package quantum_computing: a simulator of quantum computing
17 * new code to commute conjugate of derivative (Commit [565fcf])
18 * new function gnuplot_send (Commit [54380c])
19 * plot2d, plot3d, mandelbrot and julia now use gnuplot_pipes by default
20 in all operating systems and in all cases (plot shown on the screen or
21 saved to a graphics file). No temporary files are used.
22 * new plot option window. It can be used to send the plot to a window
23 different from the default 0 window.
27 * draw: Restored the detfault gnuplot_pipes format (Commit [a54f2f])
28 * draw: Restores the window, font and size options for defaut
29 terminal (Commit [096f0b])
34 Changes in the Windows installer:
35 ---------------------------------
36 * Update SBCL, wxMaxima, TCL/TK.
37 A newer Gnuplot version is available, but causes problems when using
38 pipes on Windows, therefore that was not updated.
39 * Use the HTML manual (not the PDF version) in the start menu.
40 * Strip included C programs (saves some space).
