Packages modified in this release:

• CLHEP v1.7
  New HepPDT package, and synch with official CLHEP 1.7.

• CLHEP Matrix v2.0
• ErrLogEx v2.0

• HepTuple v2.0.5
• SpecialFunctions v1.3.1

CLHEP v1.7, cvs rtag V01-07-00

New sub-package: HepPDT
This is the particle properties layer of StdHepC++.
• Properties (from the Review of Particle Physics, various generator tables, or elsewhere) of particles.
• Decay channel information.
• Mechanism for forcing custom decay chains.
Internal version number for HepPDT is 1.0.1.
Caveats:
• At this point, we recommend using this only to obtain particle properties. Decay channel mechaisms are still undergoing testing.

In Vector package:
• Improved Error Message:
  Corrected a confusing error message given when constructing a boost providing zero as the direction.
• Production status:
  The Vector subpackage is now declared to be in production.
  See the related PhysicsVectors package for FeatureLog and ProblemTracking.

In Matrix package:

• Pedantic changes for compilation of standard-strict HP compiler.
  
• The Matrix subpackage is now declared in production status.
  A FeatureLog and ProblemTracking are in CLHEP/Matrix.

In Geometry package:

• Brought up to current version in CERN cvs repository.

CLHEP 1.7

This brings all the CLHEP packages into synch with the CLHEP 1.7 official distribution (or later changes).

ErrLogEx v2.0; cvs rtag V02-00-00

Production release (no longer beta).
FeatureLog and ProblemTracking files are available.

HepTuple v2.0.5 cvs rtag V02-00-05

New features in release.
New checks and exceptions:
• Added a new exception in several places in ColumnT to catch the case where the user has not specified a span for an index variable.
• Test for the user presenting a value for an index variable that is bigger than the previously advertised maximum value. ZMthrow if it occurs.
Problem fixes:
• Fix an obscure bug in HepHBookFileManager concerning a slight misfire in the implementation of HepFileManager::cd( string target ) when target was "//".
• Remove an ill-advised test on column name string length in HBookNameTag.cc. There is a requirement on block name string length but not column names.
Documentation improvements:
• Add some documentation for the Hist1DArray, Hist2DArray and HistProfArray classes.
Dependencies:
ZMutility v1.3.7 or higher
Exceptions v1.2.1 or higher
ISOcxx v1.1 or higher
Optional:
• Cernlib library must be linked in for HBOOK
• histo v5_0_3a0 or higher for histoscope
• root v2_26_00 or higher for ROOT

SpecialFunctions v1.3.1, cvs rtag V01-03-01

New Features in release:
Documentation update and minor tweaks.
Some enhancements updated in GNU Scientific Library gsl 0.9.
A full move to 0.9 is not going to be done. The package will soon move to rely on gsl 0.9.1 which is already available.
Platforms checked:
Linux (KCC)
Irix (KCC)
Irix (gcc)
Dependencies:
• Exceptions v1.3 or higher.
• ZMutilitiy v 1.5 or higher.
