------ CGAL 2.2 is out ---------
Version 4.58 on 13 September 2000
- Last fix was not correct. Try this one...
Version 4.57 on 10 September 2000

Version 4.54 on 1 September 2000
- Renamed Interval_base::overlap() to do_overlap().
- Fixed min/max issue for VC++ in the test-suite.
- G++ on x86 now uses an asm() instead of a statement-expression + volatile
for stopping compiler optimization. It's faster, doesn't warn, and works
with 2.96.
- Removed the default copy ctor and assignment ctor for the intervals. This
did not show any difference on orientation() with G++ 2.9[56].
- Removed warning in include/bench_generic.h with G++ 2.96.
- Moved the constant propagation stoppers just where needed instead of in the
constructors : faster (but not pretty...).
- src/Interval_arithmetic.C:FPU_empiric_test() doesn't use "volatile" anymore,
this should please KCC (and Stefan :).
- CygWin now uses an inline assembly for the buggy sqrt().
- Filtered predicates are now "static" for compilers not supporting partial
specialization (CGAL_CFG_MATCHING_BUG_2), i.e. M$VC++.
Version 4.53 on 20 August 2000

- Moved Interval_base to its own file Interval_base.h.
- Moved Protect_FPU_rounding<> to _FPU.h.
Version 4.49 on 21 June 2000
- Fixed a bunch of namespace issues.
- Interval_nt is now a template class.
- Template parameter "Protection" of Filtered_exact is now a bool.
- The filtered predicates now use Protect_FPU_rounding, and the 2 dynamic
versions are merged. They could become nice function-try-blocks if GCC
produced working code for them !!!
Version 4.48 on 15 June 2000
- Removed obsolete (and buggy) references to
CGAL_CFG_NO_EXPLICIT_TEMPLATE_FUNCTION_ARGUMENT_SPECIFICATION.
- Interval_nt operations boosted with Protect_FPU_rounding().
Version 4.47 on 13 June 2000

templates.
- Fixed Copyright dates and coordinator fields re-added.
Version 4.46 on 12 June 2000
- Debuggued Lazy_exact_nt<>.
Version 4.45 on 11 June 2000

Version 4.42 on 4 May 2000
- Added maintainer file.
Version 4.41 on 4 May 2000
- Added the assembly files for the IRIX workaround, and removed them from the
clean target in src/Interval_arithmetic/makefile.
- Updated predicates for release 2.2-I-15.
Version 4.40 on 13 March 2000
- Added KCC/Sun support.
- Updated predicates for release 2.2-I-8.
Version 4.39 on 22 November 1999
- Fix test-suite bug detected by CHECK_EXACTNESS (global intervals initilized
with incorrect rounding mode).
Version 4.38 on 15 November 1999
- Fix the test-suite for VC++ without LEDA.
Version 4.37 on 11 November 1999
- Removed stupid Borland warning.
Version 4.36 on 7 November 1999
- Added C9X standard compliant rounding mode functions.
- Changed the enums FPU_cw_near... to macros CGAL_FE_TONEAREST...
Version 4.35 on 7 November 1999
- Replaced the macros CGAL_IA_SMALLEST (resp LARGEST) by static data members
Interval_nt_advanced::Smallest (resp Largest).
Version 4.34 on 3 November 1999
- The script now recognizes the per predicate marker /*CGAL_NO_FILTER*/.
- Added an exact converter from double to Quotient<Gmpz>, so that
Filtered_exact<double, Quotient<Gmpz> > works.
- Added missing includes in tst0.C.
Version 4.33 on 28 October 1999
- New filters:
- Comment out the re-adjustment stuff. The bound only grows now.
- Add counters per predicate: "number_of_failures" and "number_of_updates".
- Restricted_double is now a typedef for double, unless
CGAL_IA_CHECK_RESTRICT is defined.
- Workarounds for Borland:
- initialize the FPU mask correctly so that we don't get useless FPE.
- it doesn't have correct IEEE comparisons -> is_valid() workaround.
Version 4.32 on 22 October 1999
- Enable the sqrt workaround for Cygwin/GCC too.
- New flag CGAL_IA_NO_INLINE which makes static instead of inline the
operator* and operator/ over intervals. It reduces code size and can speed
up algorithms which use large predicates (but slow down the others).
Version 4.31 on 20 October 1999
- Removed Lazy_exact_nt.C from the test-suite (it's experimental stuff).
- New experimental filter stuff is now protected with
"#ifdef CGAL_IA_NEW_FILTERS" in the code, to protect against VC++ failures.
- Hopefully it's ready for release 2.1 now ! :)
Version 4.30 on 19 October 1999
- Added one more missing header.
- Documentation updates: new flags CGAL_IA_NO_X86_OVER_UNDER_FLOW_PROTECT and
CGAL_IA_DONT_STOP_CONSTANT_PROPAGATION.
- Constant propagation stopping is on by default, and has a new implementation
for GCC which should be zero-cost thanks to __builtin_constant_p() :-).
- Put all operators on Interval_nt* friend instead of member, and got rid of
the particular version for doubles.
- Finally got rid of Interval_nt::bound_t, as well as Double_IEEE.h.
- New file src/Interval_arithmetic/workaround_4_ms.c that defines a C function
to compute sqrt(double). The problem is that it must be compiled _with_
optimization. I ship the .obj too.
- force_ieee_double_precision() does the same things on VC++ and Borland, as
on Linux/x86.
- Don't submit test files for the experimental stuff [yet].
- Lazy_exact_nt<> is now supposed to work ;)
Version 4.29 on 13 October 1999
- Added headers to the automaticaly generated static_infos files.
Version 4.28 on 13 October 1999
- Formatting changes.
- Removed "inline call before definition" warning detected by MipsPro.
- Added #include<float.h> for Borland.
- Added parenthesis around double computation to prevent MipsPro from changing
expression computation order...
- Removed convert_to<Interval_nt>(). This was useless and broke MipsPro.
- is_valid() workaround for MipsPro.
- Removed qualifier "throw(...)" of overlap_action(), it speeds things up on
GCC.
Version 4.27 on 12 October 1999
- Fixes for Visual C++. Most tests pass correctly now.
- New file "KNOWN_PROBLEMS" (in CVS, not submitted) that describes all
IEEE related problems found in this package, as well as the workarounds.
Version 4.26 on 11 October 1999
- New class Double_IEEE (in Double_IEEE.h), which is a wrapper for a double,
but with corrected operators so that it's IEEE 754 compliant (enough).
- Replaced lot's of .inf() and .sup() by ._inf and ._sup, using friend
functions. Hopefully it works... faster.
- Remove special version of operator*(IA, double) and operator/(IA, double).
They were faster than the normal one, but not that used, and potentially
risky.
- Put overlap_action() private.
Version 4.25 on 11 October 1999
- Borland version of the rounding mode changes.
Version 4.24 on 10 October 1999 [ not submitted ]
- New class Lazy_exact_nt<> (in a preliminary state).
- Replaced CGAL_CFG_NO_EXPLICIT_TEMPLATE_FUNCTION_ARGUMENT_SPECIFICATION by
CGAL_CFG_NO_PARTIAL_TEMPLATE_FUNCTION_ARGUMENT_SPECIFICATION or
CGAL_CFG_MATCHING_BUG_2 where appropriate.
- More Visual C++ fixes.
Version 4.23 on 7 October 1999
- New file include/CGAL/Arithmetic_filter/dispatch.h which contains the list
of #include<> for the overloaded predicates, so that they are automatically
included.
- Added <sign_of_determinant.h>, <Regular_triangulation_ftC3.h> and
<Regular_triangulation_rtH3.h> to the list of filtered files.
- Removed references to CGAL_IA_NO_WARNING and CGAL_IA_NO_EXCEPTION, I think
it's not useful. Documentation updated.
- Removed Static_adaptative* and fused it in Filtered_exact<CT, ET, Static>.
- Full template is now:
template < CT, ET, Type = Dynamic, Protection = Protected,
Cache = No_Filter_Cache >
- New subdirectory and files Arithmetic_filter/static_infos/* that contains
the definition of the static variables. It is sourced by
src/Interval_arithmetic.C.
- The 4 types of filter are now mostly ready.
- Simplified #if/#else/#elif stuff in _FPU.h, it should not break anything...
- Changed ccClass to ccClassTemplate in the doc, at Susan's request.
- predicates_ftC[23].h -> predicates/kernel_ftC[23].h.
- Removed examples/ directory. Put the script in scripts/.
- Optimize is_valid(Interval_nt).
Version 4.22 on 2 August 1999
- New class Static_filter_error (in Static_filter_error.h) that helps
computing static errors for static filters.
- New class Restricted_double, which is a double with restricted
functionnality.
- New filtering scheme Static_adaptatif_filter [not 100% ready yet].
- Added predicates/sign_of_determinant.h to the list of parsed files.
- Added missing "template <>" to keep MipsPro 7.3 happy.
- New function "FPU_CW_t FPU_empiric_test()" used by expensive checks.
- Replaced CGAL_IA_DEBUG by expensive checks.
Version 4.21 on 20 July 1999
- Removed the buggy [1;-1] interval, users just have to write good code.
- New flag (disabled by default) -DCGAL_IA_STOP_CONSTANT_PROPAGATION, that
stops the constant propagation done by the compiler.
- New FPU_get_and_set_cw() function.
- Big rewrite of the Perl script.
- CGAL_DONT_NEED_FILTER replaced by C++ comments //CGAL_NO_FILTER_BEGIN {END}.
Version 4.20 on 8 July 1999
- Changed back __asm__ to asm.
- Removed tstlink in the test-suite (which was not submitted anyway).
- Test CGAL_USE_GMP before using Gmpz.h.
- Documented the caching feature Cache_t of Filtered_Exact<>.
- Documented Interval_nt_advanced::number_of_failures.
- Documented .exact(), .interval() and .value().
Version 4.19 on 6 July 1999
- The script now locally (in the produced file) defines
"CGAL_DONT_NEED_FILTER", so the user can conditionnaly exclude some code
in the produced file with "#ifndef CGAL_DONT_NEED_FILTER". For example,
some predicates that don't need to be filtered because they are already
exact (e.g. lexico*).
- Fix for MipsPro.
- New function force_ieee_double_precision(), that sets the correct IEEE
double precision on Intel only.
- CygWin compiles.
Version 4.18 on 30 June 1999
- Cleaned up _FPU.h, no more CGAL_*ASSEMBLY* macros, using GNU libc macros
on Linux/PPC (x86 keeps the old asm() for compatibility with libc5).
- _FPU.h ported to M$ VC++, though it needs testing.
- Removed obsolete lower_bound() and upper_bound().
- CGAL_IA_FORCE_TO_DOUBLE() revised on __i386__, it should be slightly faster.
- Removed the template ctor for Filtered_exact<>.
- Added "std::" where missing.
Version 4.17 on 24 June 1999
- Removed the ".pure" and src/*.o files.
- Removed include/CGAL/Arithmetic_filter/predicates_on_rtH2.h.
- Updates the other specialization files.
Version 4.16 on 24 June 1999
- Added specializations for the regular triangulation predicates.
- The script now adds "CGAL::", so that it works for the predicates
outside namespace CGAL.
- IO operators are now in libCGAL, not inlined anymore.
- Preliminary not-working-yet Linux/PowerPC support contributed
by Pierre Angelier.
- Removed the old FPU_set_rounding_to_{zero|nearest|...} functions.
Version 4.15 on 25 May 1999 [CGAL release 2.0]

- Fixed small bugs.
- Updated documentation.
Version 3.7 on 15 April 1999
- Partial workaround for lack of partial specialization of the predicates.
- New template parameter "Filter_Cache" to Filtered_exact<CT,ET> to allow
caching of the conversion to intervals (default is off).
Version 3.6 on 15 April 1999
- Final (hopefully) workaround for the rounding modes on IRIX.
- Workaround for lack of convert_to<target>(source), replaced by
convert_from_to(target(), source).
Version 3.5 on 1 April 1999

- Added lots of checks enabled with CGAL_IA_DEBUG.
- Updated rtH2 predicates.
- Fixed CGAL_convert_to<>() functions with respect to rounding mode, and
template<>.
- Assembly for Mips disabled.
- Added CGAL_FPU_get_rounding_mode() and CGAL_FPU_set_rounding_mode(). Not
documented for the moment. And test program tst0.C for that.
Version 2.6 on 10 December 1998
- Big renaming that does:
- /Filter/ -> /Arithmetic_filter/
- Filter.h -> Arithmetic_filter.h
- CGAL_FILTER_H -> CGAL_ARITHMETIC_FILTER_H
- CGAL_Filtering -> CGAL_Filtered_exact
- CGAL_to_exact_type -> CGAL_convert_to
- CGAL_to_IA[advanced]-> CGAL_convert_to<IA[advanced]> ()
- SunPro and MipsPro are definitely not supported anymore.
- Support for ftC3 and rtH2 (partially) is included.
- Massive doc update.
- The whole thing is supposed to be really "frozen for 1.2" now.
- Mips assembly enabled back, hopefully Geert-Jan has upgraded to 1.1.1,
and the problem will be fixed.
Version 2.5 on 26 November 1998
- Mips assembly commented out, it fails for the test-suite...
- Filtering stuff in place, doc updated.
Version 2.4 on 12 November 1998
- Mips + GNU uses assembly versions (thanks to Christoph Burnikel).
- CGAL_{sign,compare,abs,min,max,is_valid,is_finite} specialized for speed and
correctness.
- <CGAL/Filter.h>: new file containing the wrapper for filtered predicates.
- include/CGAL/Filter/predicates_on_ft_C2.h: new file containing the
specializations for the filtering scheme.
Version 2.3 on 23 October 1998
- the test-suite now includes some benchmark.
- the code is optimized, even uses the GNU extension "named return value".
Version 2.2 on 16 October 1998
- removed more spurious constructors.
- removed bugs in _FPU.h
- much improved test suite, 100% coverage (except casts).
Version 2.1 on 11 September 1998
- "lines too long" problem fixed.
- removed temporary objects => faster.
Version 2.0 on 17 August 1998.
- Added CGAL_to_interval_nt() cast functions for Gmpz and
leda_{real,rational,integer,bigfloat}.
- Added operators +=, -=, *=, /=, as required for all CGAL NTs.
- Moved private files to the directory CGAL/Interval_arithmetic
- Doc update: cgal.bib removed, geombib is updated.
- Using CVS.
- [sent Stefan the necessary updates to other NTs].
Version 1.6 on 10 May 1998.
- "package" line added in the headers.
- Added a CGAL_warning_msg() when you compare 2 overlapping intervals,
disabled by the compilation flag CGAL_IA_NO_WARNINGS (or CGAL_NO_WARNINGS).
- New private member function: overlap() (same semantic as operator==()).
- Doc updates:
- better introduction.
- fixed bugs shown by the HTML version.
- update the support status for the Alpha.
- modifications from Remco for 1.0.
- reference to our (BBP) ACM SoCG'98 paper added.
- ChangeLog file created.
Version 1.5 on 26 February 1998.
- Added "#include <assert.h>" forgotten in 1.4.
Version 1.4 on 6 February 1998.
- Changed _FPU_* to CGAL_FPU_*.
- Doc updates.
Version 1.3 on 16 December 1997.
- Added an assertion when defining an interval with the lower bound greater
than the upper. Disabled when CGAL_NO_PRECONDITIONS is defined.
Version 1.2 on 16 December 1997.
- Added support for old Irix 5.3 include files.
Version 1.1 on 16 December 1997.
