ChangeLog

2017-05-01  Ales Cepek  <cepek@dodo>

	* matvec 1.02 - user defined initializer replaced by
	std::initializer_list

2016-08-19  Ales Cepek  <cepek@biggy>

	* patch by Greg Troxel
	fixed "test ==", which is a bash extension and not POSIX compliant

2016-08-14  Ales Cepek  <cepek@gnu.org>

	* new release 1.18

	This is a maintainer's version introducing some minor technical
	changes and important syntax changes in configure.ac (many thanks
	to Greg Troxel <gdt@lexort.com> for the patch and testing on OS X
	10.9, netbsd-7 i386 and netbsd-7 amd64).

	* configure.ac : patch by Greg Troxel <gdt@lexort.com>
	  CPPFLAGS was set with +=, which is a bash extension and fails on
	  POSIX-conforming shells.  This resulted in sqlite3 support not being
	  enabled on NetBSD, even though the sqlite3 library was found and
	  linked in.

	* fixed some minor problems reported by Greg Troxel (doc, NEWS)
	* in local/network.cpp commented out // removed_obs.clear();
	* fixed a formatting bug in outlaying terms (due to c++11)
	* fixed a bug in HTML parser test
	* Simplified class LocalPoint. Removed helper classes XYZ, XY and
	  ZZ, replace by correspondning constructors. Removed exceptions
	  from x(), y() and z() methods; user of the class is responsible
	  for correct usage of LocalPoint objects, i.e. for calling
	  test_xy() and test_z().
	* fixed a bug in sql export reported by Dominik Hladik
	* added @documentencoding UTF-8 into gama.texi

2015-11-08  Ales Cepek  <cepek@gnu.org>

	* new release 1.17

	This is a maintainer's version introducing some basic functions
	for handling inconsistent systems (like right-handed coordinates
	with left-handed angles). Gama-local program solves this problem
	by internally changig signs of all Y coordinates, together with
	observed Y coordinates and Y differences (vectors).

	All y signed information is changed in the output. This works file
	for batch processing (gama-local) but fails in interactive
	dialogue environment of Qt based gama-q2 where all input
	information can be edited by user and changed signed Y coordinates
	(and observations) must be switched only once.

2015-07-25  Ales Cepek  <cepek@gnu.org>

	* fixed two bugs reported by Greg Troxel <gdt@lexort.com>
	** The bug with the tests is that they specify /bin/bash as the shell.
           POSIX does not require bash to be present.
	** Bad conditional in test for availability of xmllint parser.

2015-07-24  Ales Cepek  <cepek@gnu.org>

2012-07-26  Ales Cepek  <cepek@gnu.org>

	* Fixed a bug reported by Anton Horpynich <anton@vingeo.com>

	The computation of approximate coordinates failed if an angle
	needed for computing of an intersection was smaller than 0.15
	radians / 10 gons (implicit testing criterion). Although this is a
	reasonable limit for standard surveying networks, in a batch
	computation of approximate coordinates a much smaller value can be
	sometimes acceptable. It is more or less a matter of personal
	opinion if this is to be supposed a bug or not.

	Gama newly solves approximate coordinates in two main loops.
	During the first loop the default value 0.15 in class Acord is
	used.  If afterwards there are still some coordinates remain
	missing Gama starts a second loop with series of iterations in
	which firstly tries to find a solution with the default value
	then secondly with a very tiny limit of 0.0015 radians.

	In most cases all coordinates are solved in the first loop with
	the default small angle limit 10 gons.
