	New release 2.15 (maintenance release)

	* observation reductions are separated from observed values in
	GNU_gama::local::Observation objects (now is possible to
	repeatedly calculate reductions in linearization adjustment cykle
	if needed; observed raw data are not changed during the adjustment).

	* Conditional debug build #add_definitions(-DDEBUG_REDUCED_OBS) to
	display reductions of observations

	* Cleaning up code in gnu_gama/local/acord/reduce_observations.h|.cpp

	* A minor fix in gnu_gama/local/language.cpp. The english
	abbreviation for zenith angle was '_zenit_' which looked more like
	a typo than as an abbrevitaion and was changed to '_zen.__'.

	* Added four methods to the class GNU_gama::local::Point,
	reduction(), set_reduction(), unset_xyz() and test_xyz()

	* Undocumented extension to enable previous XML syntax
	'<gama-xml>' in lib/gnu_gama/xml/gkfparser.cpp

	if (!strcmp(c, "gama-xml")) return tag_gama_xml;


2021-02-28   Ales Cepek <cepek@gnu.org>

	* new release 2.14

	* fixed html output format. In qgama widget QtTextEdit rendered
	wrong tables with colspan attributes an all <td> tags had to be
	written explicitly. Occured in table of adjusted coordinates.

	* changed spelling homogenised to homogenized

	* Explicit initialization of pointer members in g3::Model constructor
	The bug reported by Greg Troxel: SparseMatrix <>*  A; in g3/g3_model.h

	* removed 'final' specifier for local observations destructor in
	lib/gnu_gama/local/observation.h


2021-01-15   Ales Cepek <cepek@gnu.org>

	* new release 2.13

	* Conversions between yaml and input xml (gkf) tested for all
	available data files in the tests suite (subdirectory gama-local).

	* Command line programs gama-local, gama-local-yaml2gkf and
	gama-local-gkf2yaml can now read input data from standard input.


2020-11-20   Ales Cepek <cepek@gnu.org>

	* new release 2.12

	* Alternative support of input data based on YAML format. YAML
	support was added for gama-local as an alternative to the existing
	XML input format. The YAML support is currently limited only to a
	conversion program gama-local-yaml2gkf but it may be fully
	integrated in gama-local program later.


2020-10-27   Ales Cepek <cepek@gnu.org>

	* new release 2.11

	* In test suites all template input files *.in (used to generate
	test shell scripts *.sh) were renamed to *.sh_ . Tests suit
	subdirectory scripts were renamed to src.

	It was slightly confusing to have input files named as *.in
	because this extension is used in Makefile.in files which are
	generated from Makefile.am.

	* Added a new option --enable-extra-tests (default is no) to the
	configure.ac script. Extra gama-local test may be running
	substantially longer (for example see railway-control.gkf).

	* Removed obscure adjustment parameter
	'update-constraiend-parameters'. The update effected SqliteReader
	lib/gnu_gama/local/sqlitereader.cpp, classes LocalNetwork and
	GKFparser and file gnu-gama-data.xsd.

	* Removed gnu-gama-data.dtd and all its references (superseded by
	.xsd), several XML files were updated in tests/gama-g3 to use
	gnu-gama-data xsd definition.


2020-09-25   Petra Millarova <millapet@gnu.org>

	* new release 2.10
