2000-05-24  Frank Hoeppner  <[e-mail]> (0.3.5)

	* revised manual (several minor improvements, typos)

	* added seqc-mode (connect attribute) which enables line-drawings
	instead of point-drawings, for instance when plotting validity
	versus number of clusters (see getting start chapter)

2000-05-23  Frank Hoeppner  <[e-mail]>

	* compiler switch -Wall is activated in --enable-debug mode,
	removed compiler warnings

	* fcplf becomes part of FC package (set clustering)

2000-05-22  Frank Hoeppner  <[e-mail]>

	* adapted qc to work with line segments 

	* norm tool is new, moved some normalizing functionality from mesh
	and wins to norm, making the tool behaviour more consistently.

2000-05-16  Frank Hoeppner  <[e-mail]>

	* qc tool is new

2000-05-11  Frank Hoeppner  <[e-mail]>

	* reorganized algorithm template fcalg.nw. It is now sensitive to
	local tags ONEPASS (O) and ITERATION (I).

	* a first simple (fcm) test is now part of the fc package (new
	subdir test/ contains test script and precalculated
	results). Tests are executed via `make check'

2000-05-10  Frank Hoeppner  <[e-mail]>

	* comp tool is new

	* join script is new

2000-05-09  Frank Hoeppner  <[e-mail]>

	* push tool is new

2000-05-06  Frank Hoeppner  <[e-mail]>

	* merged options `quiet-mode' and `linkage-output', now there is a
	single option `output' that can be set, amongst others, to `none'
	(corresponds to quiet) or `all' (corresponds to linkage-output).

2000-05-05  Frank Hoeppner  <[e-mail]>

	* gsv/xsv is able to connect point data with lines. It is possible
	to connect a data object with its predecessor in the data set or
	predecessor in the hierarchy, see hierarchy chapter in documentation

2000-04-14  Frank Hoeppner  <[e-mail]> (0.3.4)

	* bugfix: self was not compiled in non-debug mode (error)

	* new Feature class `TreeFeature' and `FullFeature', which extend
	the BasicFeature by range and hierarchy elements. TreeFeature is
	used by stc, qfcm, etc. FullFeature is used by gsv, xsv.

2000-04-11  Frank Hoeppner  <[e-mail]> (0.3.3)

	* gsv detects grid data at the end of the features symbol
	automatically. Zero weights are not used any longer to distinguish
	non-grid data from grid data. Thus, you can display a
	weight-surface by "gsv -g 3 -Z weig" which was not possible
	before.

2000-04-06  Frank Hoeppner  <[e-mail]>

	* new wins tool (sliding window)
	
	* bugfix: TurnIntoPointMap (used by gsv and xsv) now respects
	lines when estimating bounding box of `selected attributes'

	* bugfix: gsv has called gnuplot multiple times, even with
	multiple plots only one call is required.

2000-04-05  Frank Hoeppner  <[e-mail]>

	* unsupervised clustering with global validity measures
	(unsupervised fcm) implemented (no longer cini|fcm, but fcm -v)

	* new stc tool (set of n 2D data objects <-> n-tuple conversion)

2000-04-04  Frank Hoeppner  <[e-mail]>

	* algorithms and their methods are no longer "const", there is no
	need for mutable attributes any longer

2000-03-30  Frank Hoeppner  <[e-mail]>

	* unsupervised clustering reorganized (hccl, new lini
	initialization), unsupervised hccl becomes part of the package

	* mesh tool scales data (new data-scale attribute)

	* bbox tool is new (new bounding-box attributes, respects data
	attributes, lines and hierarchies)

	* bugfix (save), successor algorithm has not been called

2000-03-24  Frank Hoeppner  <[e-mail]>

	* fcrm documentation improved
	
	* gsv handles point/line data legend more carefully

2000-03-20  Frank Hoeppner  <[e-mail]> (0.3.2)

	* configure.in detects whether <getopt.h> is available. If it is
	not, no command line arguments are evaluated (use corresponding
	DDL symbols instead).

2000-03-16  Frank Hoeppner  <[e-mail]> (0.3.1)

	* gsv can display line attributes (which are used by hccl)
	
	* improved feature selection, transformation handles products

	* added hccl tool, several minor bugfixes in self, fcrm

2000-02-21  Frank Hoeppner  <[e-mail]>

	* replacing static Chars<n> with dynamic STL string

2000-02-04  Frank Hoeppner  <[e-mail]> (0.3)

	* version numbering will be consistend with GNU style; starting
	with beta version 0.3

	* first version of self tool (select features) and fcrm (fuzzy
	c-regression model)

2000-01-10  Frank Hoeppner  <[e-mail]>

	* massive structural changes; reorganizing all functions as
	instances of algorithms (C++ class) that can be combined easily
	just as it is done on the command line

2000-01-04  Frank Hoeppner  <[e-mail]>

	* changes in documentation (programs structured in chapters, new
	hierarchy chapter). New validity measure "partition coefficient".

	* release of version 0.2.2

1999-12-23  Frank Hoeppner  <[e-mail]>

	* modified flat: the weight factor is applied to non-hierarchical
	data, too. This allows to set the data weights to the memberships
	of cluster i, for example. Then, cluster i can be analysed for
	further subclusters (hierachical fuzzy clustering as proposed by
	Geva).

	* pick is new

1999-12-16  Frank Hoeppner  <[e-mail]>

	* first version of section ``getting started'' finished 

	* gsv displays axis labels

1999-12-15  Frank Hoeppner  <[e-mail]>

	* gsv and xsv display datum and prototype ``lines'' (used by HcCL) 

1999-12-14  Frank Hoeppner  <[e-mail]>

	* once again reorganized the gsv tool. It is now possible to
	create postscript documents with multiple plots, gsv supports the
	time axis just like the xsv tool.

1999-12-08  Frank Hoeppner  <[e-mail]>

	* bug in calculation of validity measure ``separation'' 

	* release of version 0.2.1
	
1999-12-02  Frank Hoeppner  <[e-mail]>

	* started a ``getting started'' section in documentation (not yet
	included in distribution)

	* added cini tool (center initialization)

1999-11-26  Frank Hoeppner  <[e-mail]>

	* added mini tool, ddlimport was missing in the distribution 

1999-11-01  Frank Hoeppner  <[e-mail]>

	* first release date (0.2)

1999-10-26  Frank Hoeppner  <[e-mail]>

	* Tutorial polished, reorganized the DDL language definition. Now,
	symbols are defined when they are used for the first time (this
	seems much more readable to me than having a never ending list of
	definitions).

	* Bugfix in gk/gg (gg is new).

1999-10-07  Frank Hoeppner  <[e-mail]>

	* In order to obtain scale-preserving 2D contour plots with
	GnuPlot, the (gsv) script has been rewritten. Now, the contour
	plot is written into a file and processed by some awk scripts.

1999-10-04  Frank Hoeppner  <[e-mail]>

	* contour plot (2d) with gsv

	* improved documentation

1999-09-20  Frank Hoeppner  <[e-mail]>

	* introduced mini and save tool

1999-09-15  Frank Hoeppner  <[e-mail]>

	* introduced new clustering algorithm FccX which partitions data
	series. FccX Prototypes are sets of conventional prototypes.

1999-09-14  Frank Hoeppner  <[e-mail]>

	* Options contain Selector instances instead of identification
	strings. Moved template functions (to operate with Selectors) in
	separate file.

	* introduced new flat tool

1999-09-12  Frank Hoeppner  <[e-mail]>

	* xsv sets the red/blue/green and bounding box of DataView
	automatically with each new DDL analysis

	* introduced mesh options to control number of mesh points etc.

1999-09-10  Frank Hoeppner  <[e-mail]>

	* removed protupdate.nw; prototype update functions are now
	defined together with the corresponding algorithm

	* removed m_number_analyses from options. It is easier to count
	the analyses in the program than to keep this number consistent
	within the DDL stream (due to interim outputs etc.)

	* introduced option.interdatadist; mesh analyses the select-?-axis
	options for x, y, and z and the inter-data-distance when creating
	the mesh.

	* redesigned the Selector class (Now using non-member template
	functions. I got internal compiler errors before.)

1999-09-09  Frank Hoeppner  <[e-mail]>

	* introduced option.select and modified icv tool (renamed to xsv,
	renamed gsg to gsv). The ``selector'' concept allows a flexible
	configuration of the display tools (and also the mesh generator).

	* the fuzzy clustering algorithms yield interim results __before__ the
	prototype update is called. If the interim result is written after
	prototype update, the distance values/membership grades do not match
	the prototypes.

1999-09-07  Frank Hoeppner  <[e-mail]>

	* introduced gsg tool

1999-09-06  Frank Hoeppner  <[e-mail]>

	* introduced mesh tool

	* splitted generic standalone executable source and AO
	source. Generic standalone source can be used for other DDL
	processing executables, too.

1999-08-18  Frank Hoeppner  <[e-mail]>

	* ICV now closes the DDL symbol correctly before exiting

1999-08-17  Frank Hoeppner  <[e-mail]>

	* added consistency checks, added command line options, improved
	documentation

1999-08-09  Frank Hoeppner <[e-mail]>

	* configure.in uses MDL_HAVE_OPENGL and detects OpenGL/Mesa
	include paths and libraries automatically. The Log/Trace usage can
	be enabled by means of --enable-debug. The existence of an SGI STL
	is checked by searching for "rope" (which is a pure SGI
	development). 

1999-07-19  Frank Hoeppner  <[e-mail]>

	* debugged several invariant violations, GK yields valid results

1999-06-26  Frank Hoeppner  <[e-mail]>

	* reorganization of algorithm instantiation

1999-02-13  Frank Hoeppner  <[e-mail]>

	* first version
