1 Maxima 5.46 change log
2 ===========================
4 New items in core:
5 ------------------
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.
9 * Added gnuplot_send to open a Gnuplot pipe and send a command to it.
10 * new code to commute conjugate of derivative (Commit [565fcf]).
11 * new plot option window. It can be used to send the plot to a window
12 different from the default 0 window.
14 New items in share:
15 -------------------
16 * new package quantum_computing: a simulator of quantum computing
17 circuits.
18 * new package test_batch_encodings: tests for batch and batchload with different character encodings
19 * new file conics_04.mac: intersections of conic sections
20 * package distrib: implementation of inverse gamma distribution
21 * package stringproc: extend the range of recognized encodings somewhat
22 * package numericalio: extend function md5sum to accept binary input stream
23 * package numericalio: recognize 1-element strings as equivalent to symbols for separators
24 * package gentran: update to new version contributed by Michael Stern
26 Changes in core:
27 ----------------
28 * plot2d, plot3d, mandelbrot and julia now use gnuplot_pipes by default
29 in all operating systems and in all cases (plot shown on the screen or
30 saved to a graphics file). No temporary files are used.
31 * option gnuplot_strings made more consistent in different terminals.
32 * option gnuplot_script_file now accepts complete path file names.
34 Changes in share:
35 -----------------
36 * draw: Restored the default gnuplot_pipes format (Commit [a54f2f])
37 * draw: Restores the window, font and size options for default
38 terminal (Commit [096f0b])
40 Changes in Xmaxima:
41 -------------------
42 * fix to allow several plotdf windows to work independently by refreshing
43 the expressions of the derivatives every time a new trajectory is plotted.
45 Changes in the Windows installer:
46 ---------------------------------
47 * Update SBCL, wxMaxima, TCL/TK.
48 A newer Gnuplot version is available, but causes problems when using
49 pipes on Windows, therefore that was not updated.
50 * Use the HTML manual (not the PDF version) in the start menu.
51 * Strip included C programs (saves some space).
52 * The command line option "--userdir" did not work on Windows, fixed that.
