These are the release notes for Maxima 5.9.1. For a detailed list of
changes in this release, see the file ChangeLog.
The updates and new features in Maxima 5.9.1 fall into three
categories: infrastructure, functionality and bug fixes.
1) Infrastructure
a) Windows
- A command-line version of Maxima is now available in
addition to the xmaxima GUI. The new command-line version
supports batch mode as well as interfacing with other
programs such as Emacs.
- Clisp is now a supported lisp on Windows.
b) Support for external interfaces
- Maxima now provides a mechanism for robust interface to
external front-ends such as TeXmacs.
c) Lisp debugger disables by default
- Maxima will no longer dump the user into the lisp debugger
when it encounters an error. The debugger can be re-enabled
if desired.
d) More Lisp implementations supported
- CMUCL, Clisp and GCL support is actively maintained.
- SBCL, ACL, and OpenMCL support is included, but no active
maintainers for Maxima using these Lisps have yet volunteered.
e) Static installs
- Maxima installs are now independent of the Lisp
implementation for CMUCL, Clisp and GCL. This will simplify
binary distributions as well as removing problems caused by
Lisp upgrades breaking existing Maxima installations.
f) "Pure" Lisp builds
- It is now possible to build Maxima using nothing but
Lisp. See the file INSTALL.lisp for details.
g) Simplified use of shell scripts
- The use of shell scripts in Maxima has been greatly
simplified. The old maxima-run-lisp script has been
completely eliminated.
- Maxima is now more portable.
- Porting to non-Unix platforms is simplified.
- Maxima is easier to maintain.
h) rmaxima
- rmaxima is a simple new front-end that gives Maxima better
command-line editing abilities, including persistent history,
for Lisps that did not have it before, e.g., CMUCL. rmaxima
requires the external program rlwrap. rmaxima is not currently
compatible with Clisp.
i) Test suite improvements
- The test suite is now available at run time through the
new command run_testsuite().
- Test suite output has been made more readable.
j) GCL performance increase
- Maxima now takes better advantage of GCL's optimization
features. The result is a substantially faster exectuable.
2) Functionality
a) Enhanced plotting
- 2D Adaptive plotting allows smooth plotting even in the
presence of singularities. The 2D plotting algorithms were
adapted from Yacas, <http://yacas.sourceforge.net>.
- Maxima's default plotter is now gnuplot. The gnuplot
interface has been greatly enhanced; see
<http://maxima.sourceforge.net> for examples.
b) New input/output labels
- Before this release, the labels input, output, and
intermediate output were C#, D# and E#. They are now %i#, %o#
and %t#, respectively. This change was made because many
users became confused when labels such as C1 clashed with
user-defined variables with similar names.
- The old behavior can be restored by with the commands:
inchar:C ; outchar:D ; linechar:E ;
b) Quadpack
- The quadpack routines for robust numerical integration have
been added.
c) Tensor
- The tensor package is now being actively maintained.
d) Differential Equations
- Enhanced differential equation solvers have been added. See
share/contrib/diffequations.
3) Bug fixes
Many bugs found in Maxima 5.9.0 have been fixed. Many bugs still
exist, however. The 5.9.3 release will focus primarily on bug
fixes. (The 5.9.2 release will focus only on case-sensitivity
issues.)
