The NEWS and TODO list for ``fcluster'':


Dec 1998 (timm)

	* version 1.2g

	* some small corrections

Thu Jan 18 17:33:52 MET 1996 (schoenfr)

	* Version 1.2f wrapped.

	* Documentation ``dokument.ps'' added (via dvips created 
	  from ~twagner/dosc/dokument.dvi). Documentation
	  ``usersguide.ps'' added (copy from
	  ~twagner/userguide/userguide.ps).

	* COPYRIGHT file added.

	* Name changed to ``fcluster'' Fuzzy Cluster Analysis.

	* Translated german error messages to english in fehler.cc.

	* Created configure.in and Makefile.in (and configure via 
	  autoconf).

	* Argument usage message expanded to be told when invoked
	  with wrong arguments.

	* Changed the use of float-typed variables to double.

	* Added dump-bitmap to the 2d/3d windows, bound to the
	  ``p'' key, and simply dumped to ``dump.xbm''.

	* More malloc/free errors fixed (``delete this'').

	* Autodependencies added to the Makefile.

	* Indent hacked and the sources formatted (urgent
	  necessary...); however, further formatting is needed.


Fri Dec 29 16:56:37 MET 1995 (schoenfr)

	* Version 1.2 wrapped.

	* Created README and NEWS file.

	* version.h created and included in fuzzy.cc und welcome.cc.

	* Various minor bugs fixed.

	* All of the ``maybe used uninitialized'' places fixed by
	  initialization with 0.

	* Classify-validity: after selection of the option, the old 
	  selected option was used. Added CLASSIFY enum to guete.h.
	  Additionally fixed by undo of some 1.0->1.1 fixes (ugly).

	* Classify-validity: reading classified data sets, does not
	  make the option selectable. fixed by patching the
	  appropriate variable after reading (ugly).

	* Classify options defaults (threshold = 0.1 amd hillheight =
	  0.5) changed to 0.01 and 0.05.

	* Some malloc-bugs removed (detected by libdbmalloc.a); many
	  are left. Needs more fixes.

	* Code cleaned up to compile with g++ 2.7.2. Not completely
	  done (many warnings about initialization of non-const from
	  rvalue).

	* Added workaround in mainwindow.cc to prevent an ugly
          internal error when optimizing with gcc v2.5.8 :-(

	* Cleanups in the Makefile done.

----------------------------------------------------------------------


TODO:

	* More code formatting (patched indent did a halfhearted job
	  on this C++ code).

	* More cleanups of memory management needed.

	* Cleanup of error-messages needed (german to english
	  translation too).

	* Verification of the code needed (but who wants this not ;-)

	* Option parsing is poor.

	* Manpage missing.
	
	* Loading of a clusterobject did not set Cluster-
