1 Maxima 5.46-post change log
2 ===========================
6 * function powerseries: power series for function lambert_w
7 (thanks to Dimiter Prodanov)
11 * package pslq: PSLQ algorithm for finding integer relations
12 among inexact numbers (thanks to Andrej Vodopivec)
13 * package nelder_mead: Nelder-Mead algorithm for minimization without
14 derivatives (thanks to Mario S. Mommer and Andrej Vodopivec)
18 * Maxima/ABCL: Use the option --noinform for ABCL.
19 This suppresses the startup messages from ABCL, so that e.g. the Maxima
20 option --quiet *is* quiet.
21 * Fix command line options for Maxima with ABCL.
22 * Functions that return lambda expressions with free variables are
23 now translated correctly. Previously many of these lambda expressions
24 would cause internal errors when called.
25 * Array functions and subscripted functions can now be translated.
26 Previously these would fail to translate with no explanation.
30 * package contrib_ode: Fix name of Clairaut differential equation
31 in code and documentation. Was misspelled as Clairault.
32 * package tensor: commit code from Toth & Turyshev paper for trace-free
33 decomposition, for time and memory assessments
34 * package namespaces: expunge this package, moved to Github
35 * package ezunits: derive units for diff, integrate, and 'at'
36 * function mnewton: optional argument for the Jacobian
41 Changes in the Windows installer:
42 ---------------------------------
43 * Update SBCL and wxWidgets.
44 * Compile a recent texinfo for building the installer. Maxima now needs
45 texinfo 6.8, but 6.7 is included in the usual build machines for
48 Bug fixes for numbered bugs:
49 ----------------------------
50 * \#545: multivar taylor gives 1^2
51 * \#608: taylor(x^a,[x],0,1) unsimplified
52 * \#3026: missing info files not well-handled
53 * \#3071: limit of expressions with signum not very powerful
54 * \#3834: abconvtest undocumented and possibly unused
55 * \#3926: Various limits give UND where they should give IND
56 * \#3972: gcl only: Autocompletion inverts command case
57 * \#3985: integrate(sin(x*cos(x)), x), risch; causes unlimited recursion
58 * \#3998: Lisp error when parser encounters eof in a comment
59 * \#4018: defint(foo,,0,inf) lisp error when denom(foo) contains %i
60 * \#4036: prederror affects bigfloat calculations
62 Unnumbered bugs fixed:
64 * commit 7a7114c: avoid call to undefined function expintegral_ei
65 * commit fe1d8cf: avoid clobbering global state when autoloading
66 * commit 70a5f78: expunge calls to 'sign' in share package distrib
70 * Help can use html docs instead of displaying help to the terminal.
