Version 3.3.7 (November 22 1999)
- Added missing headers [syl].
- Remove protect macros [syl].
- Cleaned up some useless include <Kernel/...> [Hervé]
- Shorter headers in CVS repository, but complete for release
thanks to script for submission
Version 3.3.6 (October 7 1999)
- Removed CVS conflict in Cartesian (was submitted in 3.3.5)
Version 3.3.5 (October 7 1999)
- Added include iterator_traits_pointer_specs_for_cartesian_kernel.h
in Cartesian.h
Version 3.3.4 (September 17 1999)
- Corrected template paramter of PointCd
Version 3.3.3 (September 17 1999)

Version 3.3 (September 3 1999)
- Added Point_d to Cartesian
Version 3.2.4 (September 2 1999)
- Removed references to <CGAL/Kernel/function_objects_?.h>
and copy pasted directly into Cartesian_? classes,
because M$VC++ doesn't accept this (legal?) design
- This means <CGAL/Kernel/...> are now not used, but they are kept
for the future if M$VC++ starts accepting them.
- Added definitions of Cartesian_3::*_2, even though I do not include the
corresponding <CGAL/Cartesian/*_2.?> (except for Point_2)
This only works if the compiler does lazy instantiation
Version 3.2.3 (September 2 1999)
- Release for M$VC++ which doesn't understand Base::
I renamed it to Kernel_base in all the Cartesian* classes
Version 3.2.2 (September 2 1999)
- fixed include files that still included <CGAL/...C2.h>
[worked with symlinks, but not in releases newer than 2.1-I-13]
Version 3.2.1 (Sept 1 1999)
- Release again for I-15 made in Dagstuhl
Version 3.2 (Sept 1 1999)
- Includes new predicates and construction files in C2 and C3
Version 3.1 (August 31 1999)
- Changes decided in Dagstuhl: addition of Function_objects in the kernel
- Creation of <CGAL/Kernel/{Construction,Predicate}_objects_{2,3}.h>
these files will be integrated by Stefan into his packages _2 and _3
- Addition of Point_2 in Cartesian_3 (for functionality in Plane_3)
Ver 3.0 (13 July 1999)
****EXTENSIVE CHANGES -- enough to warrant a new 3.0 release*****
- REWROTE FROM SCRATCH (Hervé)
- new <CGAL/Cartesian/...> subdirectory
predicates_on_ftC2.h put into <CGAL/predicates/kernel_ftC2.h>
basic_construction_ftC2.h put into <CGAL/constructions/kernel_ftC2.h>
- new scheme by Michael Hoffmann, which assumes partial specialization
- temporary scheme by Stefan Schirra, which does not assume it
- new config flag: CGAL_CFG_NO_ADVANCED_KERNEL to check for Michael's design
availability vs Stefan's
- Michael' scheme by default, use -DCGAL_CFG_NO_ADVANCED_KERNEL for Stefan's design
(requires $CGAL/test/NewKernel, which can be found in CGAL-2.1-I-x , x>=12)
until the flag is added in the release
- Different files for Cartesian_2.h and Cartesian_3.h
and different kernel traits Cartesian_2 and Cartesian_3
Ver 2.1 (24 May 1999)
- Resubmitted for CGAL 2.0
- Minor additions to the package, no changes in the code.
Ver 2.0 (29 Feb 1999)

- Added Point_d and Conic_2 types in CGAL_Cartesian
Ver 1.2 ( 16 June 1998)
- Inverted FT and Data_accessor declaration in cartesian_rep
NO VERSION 1.1
- Was an old symbolic version, I didn't want to reuse the same
number.
Ver 1.0 (16 June 1998)
- From Andreas Fabri and Stefan Schirra's original implementation.
- Separated from package C2 (because there was no reason that it
belongs more to C2 than to C3, and then confusion ensues).
- Changes by Stefan Schirra:
* Compile-time-tags for representation classes added in new
file representation_tags.h (included in ..._rep.h files)
* classes CGAL_PointCd<FT> and CGAL_PointHd<FT,RT> declared
in homogeneous_classes.h and cartesian_classes.h .
Corresponding typedefs added to the rep classes.

- Fixed some missing std:: for cerr
Version 3.3.3 (September 9 1999)
- renamed the scripts to spare the work for Geert-Jan
- to satisfy nice arithmetic: I skip 3.3.2 (because 3.3.3 on 9/9/99 is too nice)
Version 3.3.1 (September 3 1999)
- Added headers to .C files
Version 3.3 (September 3 1999)
- The typename added in 3.2.3 crashes VC++, hence the #define typename for VC++
- Minor bug for line_2.point(int i) (int not converted to FT) works with
builtin types but not Gmpz for instance...
Version 3.2.7 (September 2 1999)
- removed #warning which is not standard-compliant and crashes on M$VC++
Version 3.2.6 (September 2 1999)
- Changed all the typename R::FT into typename ClassC2<>::FT
for M$VC++
Version 3.2.5 (September 2 1999)

(should have been typename LineC2<R..>::Point_2)
Version 3.2.3 (September 2 1999)
- added needed typename in all <CGAL/Cartesian/*.C>
indeed, Class_2<R>::Subclass needs a typename qualifier for MIPSPRO 7.3
although it worked with the other compilers
Version 3.2.2 (September 2 1999)
- fixed include files that still included <CGAL/...C2.h>
[worked with symlinks, but not in releases newer than 2.1-I-13]
Version 3.2.1 (September 1 1999)
- f*ck CVS!
Version 3.2 (September 1 1999)

TODO: finish it so that C2 is robust with filtered
constructions and predicates
- fixed includes in Cartesian/*_2.h and Cartesian/*_2.C

even if you only include one single file (e.g. Point_2.h)
Version 3.1 (August 31, 1999)
- Added Identity into Aff_transformation
Version 3.0 (August 26 1999)
****EXTENSIVE CHANGES -- enough to warrant a new 3.0 release*****

predicates_on_ftC2.h put into <CGAL/predicates/kernel_ftC2.h>
basic_construction_ftC2.h put into <CGAL/constructions/kernel_ftC2.h>
- new scheme by Michael Hoffmann, which assumes partial specialization
- temporary scheme by Stefan Schirra, which does not assume it
- Michael' scheme by default, use -DCGAL_CFG_NO_ADVANCED_KERNEL for Stefan's design
(requires $CGAL/test/NewKernel, which can be found in CGAL-2.1-I-x , x>=12)
- each file Class_2.h is not separated into Class_2.h (interface declaration)
and Class_2.C (method definitions) for easier inclusion of all *.h before *.C
- each file Class_2.h can now be included independently of the others and of the
representation class (as long as the template parameter R defines the other
classes in the kernel)
****IMPORTANT: please note
- for now, while we still have two versions, two scripts (create_symlinks and
remove_symlinks) are included which have to be run before the test suite.
when using Michael's design. (Nothing to be done for Stefan's design!)
This is to prevent inclusion of the wrong files *C2.h and *_2.h
(now we want to include <CGAL/Cartesian/*_2.h> instead of *C2.h)

- Added id()-filters for comparaisons of kernel objects, only when there is
substantial computation before first exit point. For instance, when comparing
plane, has_on (expensive is called), therefore I compare id()s first;
on the other hand, comparing spheres compares center.x() first, which is
likely to exit, so comparing id()s not a good investment.

Should now work on M$VC++ as well because of that change
- Will work on egcs 1.1.2 once direction.vector() is changed to
to_vector() everywhere in CGAL (pending decision).
Version 3.6.2 (October 11 1999)
- Fixed projection_lineC3 that led to bug of version 3.6.1

TODO: Correct it (emergency!)
Version 3.6 (September 28 1999)
- Changed printing of Aff_transformations to look like C2
- Changed composition of Aff_transformations to better scheme, at

_general_transformation_composition have to precede their friend declaration
(at least on mips).
- corrected TetrahedronC3::operator==() with the correct definition
Version 3.3.1 (September 2 1999)
- Added headers to *.C so that Utrecht cant complain
Version 3.3 (September 3 1999)
- The typename added in 3.2.3 crashes VC++, hence the #define typename for VC++
Version 3.3 (September 2 1999)

- added needed typename in all <CGAL/Cartesian/*.C>
indeed, Class_3<R>::Subclass needs a typename qualifier for MIPSPRO 7.3
although it worked with the other compilers
Version 3.2.2 (September 2 1999)
- fixed include files that still included <CGAL/...C2.h>
[worked with symlinks, but not in releases newer than 2.1-I-13]
Version 3.0 (August 26 1999)
****EXTENSIVE CHANGES -- enough to warrant a new 3.0 release*****
- new <CGAL/Cartesian/...> subdirectory
predicates_on_ftC3.h put into <CGAL/predicates/kernel_ftC3.h>
basic_construction_ftC3.h put into <CGAL/constructions/kernel_ftC3.h>
- new scheme by Michael Hoffmann, which assumes partial specialization
- temporary scheme by Stefan Schirra, which does not assume it
- Michael' scheme by default, use -DCGAL_CFG_NO_ADVANCED_KERNEL for Stefan's
design
(requires $CGAL/test/NewKernel, which can be found in CGAL-3.1-I-x , x>=12)
- each file Class_3.h is not separated into Class_3.h (interface declaration)
and Class_3.C (method definitions) for easier inclusion of all *.h before *.C
- each file Class_3.h can now be included independently of the others and of the
representation class (as long as the template parameter R defines the other
classes in the kernel)
****IMPORTANT: please note
- for now, while we still have two versions, two scripts (create_symlinks and
remove_symlinks) are included which have to be run before the test suite.
when using Michael's design. (Nothing to be done for Stefan's design!)
This is to prevent inclusion of the wrong files *C3.h and *_3.h
(now we want to include <CGAL/Cartesian/*_3.h> instead of *C3.h)
- in order to test Stefan's design, one needs the test/NewKernel directory
when this is added to the internal release, this directory will disappear
****BUGS FIXES: in addition, since 2.1.6
- gcc 2.95 compliant (hopefully conform to the standard)
- added std:: for endl (suggestion by Stefan Schirra)
Version 2.1.6 (June 22 1999)
- Added missing std:: (sylvain)
Version 2.1.5 (May 23 1999)
- Fixed TetrahedronC3::operator==(), which was incorrect even in the
generic case (it still remains undefined in the degenerate case)
- Fixed vertex() in Triangle and Tetrahedron (for the modulus operation)
- Added CGAL:: prefix to to_double() in PointC3
Version 2.1.4 (April 27 1999)
- Bug fixes by Sylvain, CGAL::compare()
Version 2.1.3 (March 30 1999)
- made the funnelweb->code
Version 2.1.2 (March 30 1999)
- Moved #includes out of namespace CGAL
Version 2.1.1 (23 March 1999)
- Added more CGAL::sign() into PlaneC3 and DirectionC3
Version 2.1 (12 March 1999)
- Changed a lot of the formatting
- Optimized some arithmetic expressions and case/switch/test statements in
Aff_transformationC3 and PlaneC3 [Sylvain Pion]
- Finally removed OrderTypesC3, IntersectionC3 and ostreamC3
from the directory web/ (obsolete)
- Changed sign() to CGAL::sign() in PlaneC3.h, in predicates_on_ftC3.h,
to avoid potential conflicts with leda
- Changed long id() for all classes [Sylvain Pion]
[was (int) PTR, which is unsafe on some machines]
- Used CGAL::square whenever appropriate
- In SegmentC3, collinear_has_on() now uses predicate
- Removed const qualifier from local variables (turns out not needed)
- Used sign_of_determinant() instead of sign(determinant())
- Added distance_predicatesC3
- Include <CGAL/Threetuple.h> in RayC3.h
- Include <CGAL/Twotuple.h> in SegmentC3.h
TODO
? In TriangleC3, has_on() now uses predicate
? move cross_product() from VectorC3 to basic_constructionsC3
Version 2.0 (29 Feb 1999)
- Changed to namespace CGAL
- Added scaled_distance_to_directionC3 for *_signed_distance_to_plane
Ver 1.6 (4 January 1999)
- Revised inline policy in basic constructions and predicates
- Added const qualifier to all local variables that qualify for it
(greatly enhances optimization)
- Optimized the 3D predicates' arithmetic expressions
Ver 1.5 (3 December 1998)
- Changes go along two directions: constructions and predicates.
BASIC CONSTRUCTIONS:
- Added basic_constructions_ftC3
- Moved all the computation basic_constructions from basic_constructions_ftC3
- Added basic constructions:
CGAL_scaled_distance_to_plane(Plane, Point)
CGAL_scaled_distance_to_plane(Point, Point, Point, Point)
CGAL_squared_distance(Point, Point)
CGAL_projection(Point,Plane)
PREDICATES
- Added predicates_on_ftC3
- Moved all the computation from predicates_on_pointsC3 to predicates_on_ftC3
- Added the predicates on squared distances (similar to C2)
CGAL_cmp_dist_to_point(Point, Point, Point)
CGAL_has_larger_dist_to_poin(Point, Point, Point)t
CGAL_has_smaller_dist_to_poin(Point, Point, Point)t
CGAL_cmp_signed_dist_to_plane(Plane, Point, Point)
CGAL_has_larger_signed_dist_to_plane(Plane, Point, Point)
CGAL_has_smaller_signed_dist_to_plane(Plane, Point, Point)
[Plane can also be given implicitly by three points]
CGAL_cmp_signed_dist_to_plane(Point, Point, Point, Point, Point)
CGAL_has_larger_signed_dist_to_plane(Point, Point, Point, Point, Point)
CGAL_has_smaller_signed_dist_to_plane(Point, Point, Point, Point, Point)
- Simplified expressions for collinear_are_ordered_along_line
Ver 1.4 (16 June 1998)
- Added missing declaration for FT0 in some predicates
- Added are_strictly_ordered_along_line predicate

and added bounded version)
- Added the are_positive_oriented and are_negative_oriented
predicates
Ver 1.3
- Added basic_constructionsC3 (midpoint, circumcenter, projection)
Ver 1.2
- Added CGAL_NULL_TMPL_ARGS in friend operator declaration
- New inline policy is now used: There are several levels of
inlining to be defined in kernel_basic.h
Ver 1.1
- New access functions have been added to Aff_transformation. (Thanks to Stefan.)
Ver 1.0
- From the Kernel design group
