<H2>1. Supported and Tested Platforms</H2>
Official platforms:
<UL>
<LI>SUN Solaris 5.8, C++ CC-5.4 Patch 111715-02.</LI>
<LI>Linux, gcc 3.2.3.<BR>
This configuration was tested with the RedHat 7.3 distribution,
versions of Geant4 have also been compiled successfully on other
Linux distributions, like Debian, Suse or more recent RedHat systems.
The default RedHat compiler gcc-2.96 distributed in RedHat 7.X is NOT
supported. It has been verified that it produces incorrect binaries,
therefore is not reliable. See also <A HREF="#note-1">note below</A>.</LI>
<LI>Windows/XP and CygWin Tools with: Visual C++ 7.1 .NET</LI>
</UL>
More verified configurations:
<UL>
<LI>SUN Solaris 5.8, C++ CC-5.5.</LI>
<LI>Linux, gcc 3.3.3.</LI>
<LI>Linux, Intel-icc 8.0.</LI>
<LI>MacOS 10.3, gcc-3.3</LI>
</UL>
More verified configurations, which we plan to stop supporting
in releases or patches after November 2004:
<UL>
<LI>Linux, gcc 2.95.2.</LI>
<LI>Windows/2000 and CygWin Tools, Visual C++ 6.0 Service Pack 5</LI>
</UL>
Platforms configured but not tested and not supported:
<UL>
<LI>AIX 4.3.2, xlC 6.0</LI>
<LI>DEC V4.0, cxx C++ V6.1-027</LI>
<LI>HP 10.20, aCC C++ B3910B A.01.23</LI>

<H2>2. AIDA and CLHEP</H2>
Geant4 6.2 requires the <A TARGET="ext"
HREF="http://cern.ch/clhep/INSTALLATION/clhep.html">installation
of CLHEP</A>.<BR>
Tests have been performed with <B>CLHEP-1.8.1.0</B><BR>

Geant4 6.2 examples with histogramming cowork with AIDA 3.2.1
implementations. These include:

<H2>3. Compiler Specific Problems</H2>
<UL>
<LI><A NAME="note-1"><B>Linux Red Hat 7.X, gcc-2.96</B></A>.
<UL>
<LI>The default compiler distributed by Red Hat since release 7.0 is
NOT supported and not considered reliable for running a Geant4-based
application. In more than one test case, binaries produced by gcc-2.96
have shown incorrect behavior, either due to wrong order of
initialisation of static data in memory or to bugs in the system
<TT>iostream</TT> classes, problems which apparently have all been
solved in more recent versions of the compiler (3.X series).<BR>
For information, gcc-2.96 is a compiler that has never been
officially released, nor supported by the GNU team itself and is not
considered reliable by the authors (for more information, see also
<A TARGET="ext" HREF="http://gcc.gnu.org/gcc-2.96.html">http://gcc.gnu.org/gcc-2.96.html</A>).</LI>

<H2>4. Known Run-Time Problems and Limitations</H2>
For a complete list of outstanding run-time problems and to submit any
problem you may find running this version of Geant4, please refer to the
<A TARGET="ext" HREF="http://cern.ch/geant4/problemreport">Geant4 Problem Reporting
System</A>.

<!-- ============================================== -->
<H2>5. Compilation Warnings</H2>
There may be compilation warnings on some platforms. We do not believe
that any will lead to incorrect run-time behaviour.
<P> </P>
<A NAME="6."></A>
<HR>
<!-- ============================================== -->
<H2>6. Known Run-Time Warnings</H2>
The following message can be written to error output while tracking.
We believe it does not give rise to incorrect behaviour.
<PRE>
G4PropagateInField: Warning: Particle is looping
- tracking in field will be stopped.
It has performed 1000 steps in Field while a maximum of 1000
are allowed.
</PRE>

<HR>
<!-- ============================================== -->
<H2>7. Major items for migration of user code</H2>
There're not known migrations necessary if upgrading from release 6.1,
other than recompilation and/or reinstallation of libraries and user
applications.
<P> </P>
<B>Future migration for <TT>G4VParticleChange</TT> class</B>
<P> </P>
For the future releases, an interface change to the class
<TT>G4VParticleChange</TT> is foreseen. The required changes are already
implemented in this release while still keeping valid the old interface.<BR>
The following methods will be removed in the future:
<PRE>
void SetTrueStepLength(G4double truePathLength);
void SetLocalEnergyDeposit(G4double anEnergyPart);
G4TrackStatus GetStatusChange() const;
void SetStatusChange(G4TrackStatus status);
void SetSteppingControl(G4SteppingControl StepControlFlag);
void SetParentWeight(G4double);
</PRE>
They will have to be replaced by the following methods, respectively:
<PRE>
void ProposeTrueStepLength(G4double truePathLength);
void ProposeLocalEnergyDeposit(G4double anEnergyPart);
G4TrackStatus GetTrackStatus() const;
void ProposeTrackStatus(G4TrackStatus status);
void ProposeSteppingControl(G4SteppingControl StepControlFlag);
void ProposeParentWeight(G4double);
</PRE>
<P> </P>
<B>Future migration for <TT>G4GeneralParticleSource</TT> class</B>
<P> </P>
A 'tree-structured' command format is implemented in this release for
<TT>G4GeneralParticleSource</TT>. The old UI commands have been kept
for backward compatibility but will be removed in the future.<BR>

<UL>
<LI><TT>G4SDManager</TT>, <TT>G4SDStructure</TT>: added optional argument
<I>warning</I> to <TT>FindSensitiveDetector(pathName, warning)</TT>,
defaulted to <TT>true</TT>, to eventually exclude warning issued by
<TT>G4SDManager</TT> when sensitive detector is not found.</LI>

<UL>
<LI>First iteration towards new models for photoelectric angular distribution:
design iteration and re-implementation of non-polarized Sauter-Gavrila
distribution (K-shell approximation).</LI>
<LI>New model for PIXE.</LI>
<LI>Bug fix for Barkas effect.</LI>
<LI>Bug fix in energy loss concerning positrons handled by Penelope.</LI>
</UL>
<A NAME="emstd-notes">

<UL>
<LI><TT>G4VEnergyLoss</TT> and related classes:
<UL>
<LI>Corrected error in retrieving <TT>dE/dx</TT> from tables
(it affected proton around <TT>1 MeV</TT>).</LI>
<LI>Fixed a problem in retrieving physics tables from files. </LI>
<LI>Fixed a problem of energy below <TT>lowestKinEnergy</TT> (simulation of

<LI>Added new methods to define simulation options to
<TT>G4EmProcessOptions</TT>.</LI>
<LI>Revised printout format in <TT>G4VEnergyLossProcess</TT>.</LI>
</UL></LI>
<LI>Energy-loss fluctuations:
<UL>
<LI>Reduced area of applicability of the model for simulation of
fluctuations at very small steps to provide less step dependent
results in solid absorbers.</LI>
<LI>Smoothed out sampling of Gaussian fluctuations, when sigma is much
bigger than energy loss.</LI>
</UL>
The purpose of both changes is to provide results that are less dependent
on step size. For example, for steps down to 0.1 microns (in solid materials)
the energy deposition distribution in a thin absorber is not dependent on the
step limit.</LI>
<LI>Ionization for muons, hadrons, ions:
<UL>
<LI>Set the integral method to be the default (it already was for electrons).
The step remains limited to 20% of the current range, as in Geant4 5.2.</LI>

<UL>
<LI>Changes in <TT>G4MscModel</TT>: <TT>t->z</TT> and <TT>z->t</TT>
transformations (true length to geometrical length and back) have
been rewritten. The purpose is to reduce the step-size dependence of
results, which was mainly connected with simulation of multiple
scattering of low energy particles. It will affect the resolution
of sampling calorimeters.</LI>
<LI>Change in the angular distribution for <TT>e+/e-</TT>: correction
to the Highland formula for the central part of the distribution.</LI>
</UL></LI>
<LI>Multiple Scattering for ions:

for ions together with multiple-scattering.</LI>
</UL></LI>
<LI>Muon Pair Production:
<UL>
<LI>Minor fix in differential cross section: use total energy instead
of kinetic energy.</LI>
<LI>Fixed minor energy non-conservation (electron mass).</LI>
<LI>Fixed problem of calculation of maximum energy transfer to an
atom of compound materials.</LI>
</UL></LI>
<LI>PAI ionisation:
<UL>
<LI>Introduced new model <TT>G4PAIPhotonModel</TT>, PAI model that splits
the cross-section into electron and photon parts.</LI>
<LI>Removed limitations on cut values in both PAI models.</LI>
<LI>Use precise integrator for initialisation of PAI models.</LI>

<LI><B>HepRep</B>
<UL>
<LI>Renamed zlib prefix from <TT>z_</TT> to <TT>heprep_z_</TT>.
