Maxima 5.13.0 change log
Compiled 2007-08-04
Backwards-incompatible changes:
* unstore, fassave, restore: cut out undocumented functions
New items in core:
* unique: function to return unique elements of a list
* New function float_approx_equal w/ associated global
variable float_approx_equal_tolerance (for test suite cases)
* Interface to Lisp string streams: make_string_input_stream,
make_string_output_stream, get_output_stream_string
New items in share:
* vector3d package (thanks to Walter Eastes)
* Script share/share_testsuite.mac to run tests in share
* share/contrib/topoly.lisp: new functions elim and elim_allbut
New items in tests:
* Commit test scripts written by Michael Wester
Other revisions:
* run_testsuite: only simplify expected results, do not evaluate, and
do not call ratsimp; now tests are more stringent than before
* equal: recognize Maxima and Lisp arrays and Maxima and Lisp strings
* find_root: evaluate arguments in an ordinary way
* apply, outermap: evaluate arguments in an ordinary way
* save, loadfile, tex, stringout, compfile: evaluate filename argument
* display code: output space characters (no tabs)
* share/linearalgebra: improved jacobian and hessian functions
* share/contrib/lsquares.mac: replaced with a new version
* share/draw: include geographical data from World Boundaries Database;
other modifications
* with_stdout: accepts an output stream as well as a filename
* share/contrib/topoly.lisp: many improvements in to_poly
* share/contrib/numericalio: accept stream as well as a filename
* many other minor improvements
Bug fixes not otherwise mentioned:
* 1754072: $piargs bug
* 1751951: diag_matrix() with block matrices gets off-diag boxes wrong
* 1748168: integrate(1/(2+cos(x)),x,-%pi/2,%pi/2); wrong
* 1741705: integrate(1/(sin(x)^2+1),x,0,8) wrong
* 1732315: trigrat dies on a matrix

* 1729642: conjugate error
* 1729432: onep1 / FIX
* 1726002: bug in coerce-float-fun
* 1722156: powerseries((x+1)/(1-2*x^2), x, 0);

* 1714044: Maxima asks unnecessary questions in integration
* 1690374: asin(1 / sqrt(2))
* 1562340: trigrat doesn't distribute over =
* 1552789: integrate(1/(sin(x)^2+1),x,1,1+%pi) takes forever
