Release notes for Maxima 5.9.0: This is the first of a series of development releases which will culminate in Maxima 6.0, the first truly stable release of the new Maxima project. This release has known bugs; see "Known issues..." below. However, we believe it is stable enough for use by a wide audience. We are relying on bug reports from users to help us make 6.0 the most bug-free version of Maxima ever. Changes in this release include: 1) Maxima is now compatible with ANSI Common Lisp. CMUCL, Clisp and GCL are fully supported. 2) Maxima has a new build system based on the GNU Autotools. Installation should be easier and more flexible than ever before. 3) The Maxima build now uses mk:defsystem from CLOCC at the Lisp level. mk:defsystem provides a powerful and familiar environment for Lisp developers. 4) Maxima has a new User Manual, which is provided as a complement to the detailed reference manual from earlier versions of Maxima. 5) The command-line interface has been enhanced with several options, including a batch mode. 6) The bundled Emacs/XEmacs modes have been improved. 7) The internal layout of source code and shared Maxima files has been vastly improved. 8) Precision of some numerical special functions has been dramatically enhanced. 9) New and improved binary packages for Windows and Linux are now part of the official distribution. 10) Last, but not least, many bugs have been fixed. Known issues in this release include: 1) One of the (many) tests in the Maxima test suite fails. When the test suite is run via "make check" this known failure (Problem 4 in rtest15.mac) will be listed as an expected error in the summary. 2) The test suite is available in xmaxima. Xmaxima should also flag the known failure described above as expected, but it does not. This behavior will be improved in a later version of (X)Maxima. 3) When compiled with GCL, Maxima will fail to compile functions when the current working directory is not writable. This will typically cause the test suite to fail when run from xmaxima under Unix-like systems because it sets the current working directory to the installed tests directory. The end result will look like this: ------------------------------------------------------------------ /* ********************** Problem 43. *************** */ %Input is DESOLVE([EQN1, EQN2], [f(x), G(x)]) x + 2 contains more than one independent variable. -- an error. Quitting. To debug this try DEBUGMODE(TRUE);) ------------------------------------------------------------------ 4) The maxima command-line executable is only fully functional under Unix-like systems, which includes Win32+MSYS, but not plain Win32. Under Win32, the executable maxima.bat is available but it has limited functionality. (The Win32 distribution does contain xmaxima, however, which is fully functional under Win32.) This problem will be fixed in a later version of Maxima. 5) maxima.bat does not properly set the Maxima directory. This will cause several problems including the inability to access on-line help and plotting. As a workaround, set the environment variable MAXIMA_PREFIX to the installed location of Maxima, which is usually "C:/Program Files/Maxima-5.9.0". This problem will be fixed in a later version of Maxima. 6) The share and demo files have many problems. These problems will be addressed in a later release. 7) There are still many open bugs in the Maxima bug tracking database. See for details.
