Please note that this and future ZOOM releases no longer offer support for Fermi RedHat Linux 6.x. While we are not aware of any code changes in this release that would prevent a proper build on a RedHat 6 system, we have not done that build, primarily for lack of a suitable machine.

Packages modified in this release:

• CLHEP v1.9.3
  Correct a serious typo in Boost::vectorMultiplication(). See below for details.

• PhysicsVectors v2.2.1
  Update several of the tests to conform to the changes in CLHEP. Update the documentation.

CLHEP v1.9.3; cvs rtag V01-09-03

Correct a serious typo
• Supply several previously ommitted methods such as RotationX * LorentzRotation
• Repair a bug in LorentzVector::deltaR() which could return large values when the phi values are close to +/- pi.
• Correct a typo in Boost::vectorMutiplication(). 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.
• Rectify misbehaviour when isNear() is taken between a specialized or general Boost and a general LorentzRotation.
• Update the Formulas and Definitions document. Define the ranges of phi and psi for Euler angles and give the definition of the dictionary ordering comparison of Rotations.
• Update the accompanying tests including those which had been part of PhysicsVectors.

PhysicsVectors v2.2.1 cvs rtag V02-02-01

Update all the tests affected by the changes in CLHEP
• All of the tests were brought into accord with the changes in CLHEP. Because of the changes in the definitions of the comparison operators, a number of subtests had to be redefined, particularly those for LorentzVectors and Rotations.
