	* In LorentzVectorC.cc, in deltaR, replaced the direct subtraction 
	  pp.phi() - w.getV().phi() with pp.deltaRPhi(w.getV()) which behaves

==============================
23.10.03 Release CLHEP-1.9.0.0
==============================

Fri Oct 10          2003 Mark Fischler <mf@fnal.gov>

	* ZMxpv.h and ZMxpv.cc
	
	Modified the ZZMthrowA and ZMthrowC macros such that the package
	never calls exit(), throwing an exception instead.  Existing code
	in entire package was already instrumented to throw the various
	exceptions. 
	
	* Boost.h and Boost.icc and Boost.cc
	
	Correct a typo in Boost::vectorMutiplication() [that is, boost*4vector].
	This affected off-axis boosts applied to a LorentzVector when the 
	x- and/or y- components of both the Boost and the LorentzVector are 
	not small. Boosts in the z-direction are unaffected and Boosts 
	dominantly in the z-direction suffered only second-order effects. 

	Repair a bug in LorentzVector::deltaR() which could return large 
	values when the phi values are close to + and - pi respectively,
	for two vectors which are actually near each other.
	
	Rectify misbehaviour when isNear() is taken between a specialized
	or general Boost and a general LorentzRotation.
	
	Supply output operator.

	* BoostX.cc, BoostY.cc, BoostZ.cc
	
	Rectify misbehaviour when isNear() is taken between a specialized
	or general Boost and a general LorentzRotation.

	Supply output operators.
	
	* LorentzRotation.cc
	
	Multiplication by specialized rotations

	More efficient multiplicatio by a rotation

	*LorentzVectorC.cc

	Correction in isNear for two vectors both close to -Z axis.
	
	* RotationE.cc	
	
	Methods to find EUler angles phi() and psi() now forgiving of
	cos phi apparently slightly above 1 due to roundoff error.

Thu May  1 11:18:49 2003 Mark Fischler <mf@fnal.gov>

	* Vector/RotationE.cc:

	This modifies the eulerAngles() method to address a flaw
	pointed out by A. Skiba:  When the rotation matrix for a HepRotation
	was slightly perturbed due to accumulated roud-off error, and the
	rotation was very nearly but not exactly about the Z axis, the
	Euler angles computed could be incorrect in the sense that
	reconstructing a HepRotation from them would give a significantly
	different rotation.

	The new algorithm is much more numerically stable, and handles these
	cases better.

	* Vector/doc/eulerAngleComputation.tex:

	This file gives mathematical detail of the problem and the algorithm
	used to improve the numerical stability.

	* Vector/test/eulerProb.cc,eulerTest.cc (Added):

	The original program submitted by Skiba to exhibit numerical
	instability in eulerAngles() method, and a program to significantly
	excercise many different cases to verify that the improved method
	does give accurate results in the difficult and easy cases.

	Protection against taking acos(>1.0000) in cases where
	roundoff has caused a matrix element to become greater than 1.

Sun Mar 31 10:54:23 2002 Evgueni Tcherniaev <Evgueni.Tcherniaev@cern.ch>

	* Global_Clean_Up:

	The following macros have been removed from config/CLHEP-target.h.in
	(the reason is indicated). Respectively checks for them have been
	removed from configure.in:  

	  HEP_HAVE_STL       - all supported compilers have string, vector, ...
	  HEP_HAVE_BOOL      - all supported compilers have bool
	  HEP_HAVE_NAMESPACE - all supported compilers have namespace
	  HEP_HAVE_EXPLICIT  - all supported compilers have explicit
	  HEP_HAVE_TYPENAME  - all supported compilers have typename
	  HEP_HAVE_EMPTY_TEMPLATE_PARAMETER_LIST
	                     - all supported compilers have template<>

	  HEP_SQR_NEEDS_PARAMETER_WITHOUT_CONST
	  HEP_ABS_NEEDS_PARAMETER_WITHOUT_CONST
                      - current definition of sqr() and abs() works everywhere

	  HEP_QSORT_NEEDS_FUNCTION_WITH_EXTERN_C_LINKAGE - qsort() is not used

	The following macros have been removed from config/CLHEP.h:

	  HepStdString
	  HepStdVector
	  HepStdList
	  HEP_TEMPLATE_SPECIALIZATION
	  HEP_BEGIN_NAMESPACE
	  HEP_END_NAMESPACE
	  HEP_USING_NAMESPACE

	The following modifications have been made in the code:

	  HepStdString               -->    HepSTL::string
	  HepStdVector               -->    HepSTL::vector
	  HepBoolean                 -->    bool
	  HepDouble                  -->    double
	  HepFloat                   -->    float
	  HepInt                     -->    int
	  HEP_BEGIN_NAMESPACE(xxx)   -->    namespace xxx {
	  HEP_END_NAMESPACE(xxx)     -->    } // namespace xxx

	Speeed enhancements by making Rotation completely non-polymorphic,
	inlining everything that remotely seems appropriate, ordering
	appearance of inline definitions such that the inlining is ot
	defeated, and so forth.

	This addresses the issue that R*v in CLHEP 1.7 was 3.5 times slower
	than in CLHEP 1.6.  They are now the same speed.
	
Tue Dec  4 08:31:13 2001 Mark Fischler <mf@fnal.gov>

	  opposite sides of phi = - pi;
	- correct azimangle and provide deltaPhi() method;
	- set(x,y) for Hep2Vector;
	- all classes that have operator>> can now accept
	  input in same form as operator<< generates output;
	- return value if you take eta(zero vector) is zero
	  rather than 10^72;

	NaN-proofed the package:  At every place where there is a potential
	division by zero or a function that could return a memeaningless
	result or Not-A-Number, it is checked and an error message (via
	ZMthrowA or ZMthrowC) is done if there is a problem.  No silent NaN
	generation.
