Major items:
* Expand and revise Maxima reference manual (all languages),
including documentation for add-on packages and additional
figures in the HTML version of the manual
* Maxima Windows installer bundles wxMaxima user interface
* Fast integer factorization (function ifactors and friends)
Backwards-incompatible changes:
* Rename many functions in the distrib add-on package for greater
clarity
* Rename some functions in the descriptive add-on package for greater
clarity
* Change name of Xmaxima initialization script to .xmaximarc
(was xmaxima.ini)
* Cut out functions j0, j1, jn, i0, i1, and in (superseded some time
ago by bessel_j and bessel_i functions)
* Cut out functions tmlin, tmlinsolve, tmnewdet, and tminverse
(obsolete, superseded by other linear algebra functions)
* Cut out add-on packages differ and gendif (obsolete, buggy)
* load(specfun) yields message saying "specfun package superseded by
orthopoly" (specfun removed in Maxima 5.9.3)
* interpolate function yields a message saying "interpolate was renamed
to find_root" (interpolate was renamed in Maxima 5.9.3)
* Rename functions g0, g1, and gn to scaled_bessel_i0,
scaled_bessel_i1, and scaled_bessel_i, respectively.
New items:
* maxima_tempdir, maxima_userdir: Maxima variables to shadow the Lisp
variables *maxima-tempdir* and *maxima-userdir*
* share/contrib/implicit_plot.lisp: Draw implicit plots
* share/contrib/dynamics.mac: Numerical and graphical functions for
dynamical systems and fractals
* share/contrib/graph2d.lisp: Plot discrete data in Xmaxima
* share/lbfgs: LBFGS algorithm for unconstrained minimization
* share/contrib/tocl.lisp: Output a Maxima expression as Common Lisp
* share/contrib/prim: Implementation of Prim's algorithm
* tests/rtest_tex.mac: Generate a test document by calling the tex
function on a variety of expressions
Other revisions:
* plotting functions: many improvements
* Xmaxima: many improvements, including improvements in HTML rendering
* Definite integrals: several bug fixes
* Hypergeometric functions: many revisions
* zeilberger add-on package: revised
* Evaluation of definite sums and products: use faster method
* diffequations add-on package: additional tests
* tex function: several adjustments and bug fixes
* distrib add-on package: revised
* float number output: fpprintprec controls formatting for ordinary
floats as well as bigfloats
* tensor add-on packages: bug fixes
* solve_rec add-on package: minor revisions
* solver add-on package: brought up to date
* sarag add-on package: revised
* augmented_lagrangian add-on package: call LBFGS to solve
unconstrained minimization problem
* boolsimp add-on package: minor revisions
* multiadditive add-on package: revised
* rule processing: lambda expression OK for match predicate; atom OK
for match expression in defrule
* Maxima self-test suite: expanded
* Maxima rpms: Make the maxima rpm depend on a specific version of the
maxima-exec rpm, and make the maxima-exec and other rpms depend on
a specific version of maxima
* throughout: improved compatibility with Allegro Common Lisp and
Scieneer Common Lisp
Bug fixes not otherwise mentioned:
