1 Maxima 5.13.0 change log
5 Backwards-incompatible changes:
7 * unstore, fassave, restore: cut out undocumented functions
12 * unique: function to return unique elements of a list
14 * New function float_approx_equal w/ associated global
15 variable float_approx_equal_tolerance (for test suite cases)
17 * Interface to Lisp string streams: make_string_input_stream,
18 make_string_output_stream, get_output_stream_string
23 * vector3d package (thanks to Walter Eastes)
25 * Script share/share_testsuite.mac to run tests in share
27 * share/contrib/topoly.lisp: new functions elim and elim_allbut
32 * Commit test scripts written by Michael Wester
37 * run_testsuite: only simplify expected results, do not evaluate, and
38 do not call ratsimp; now tests are more stringent than before
40 * equal: recognize Maxima and Lisp arrays and Maxima and Lisp strings
42 * find_root: evaluate arguments in an ordinary way
44 * apply, outermap: evaluate arguments in an ordinary way
46 * save, loadfile, tex, stringout, compfile: evaluate filename argument
48 * display code: output space characters (no tabs)
50 * share/linearalgebra: improved jacobian and hessian functions
52 * share/contrib/lsquares.mac: replaced with a new version
54 * share/draw: include geographical data from World Boundaries Database;
57 * with_stdout: accepts an output stream as well as a filename
59 * share/contrib/topoly.lisp: many improvements in to_poly
61 * share/contrib/numericalio: accept stream as well as a filename
63 * many other minor improvements
