0113 <H2>3. Items for migration of the user code</H2>
0114
0115 Listed here is some relevant information on developments included in this
0116 release, some of which may require minor migrations for advanced uses of
0117 features in Geant4 in order to upgrade from release 8.1 to release 8.2.
0118 Note that a full re-installation of libraries (or a full recompilation) and
0119 a recompilation of user applications is anyhow required.
0120

0122 <B>Standard Electromagnetic physics</B>
0123 <P> </P>
0124 Some improvements were introduced to multiple scattering, which provide
0125 improved results for large angle scattering; better particle transport near
0126 geometry boundaries and less cut dependence for sampling calorimeters
0127 (see details in Physics Reference Manual).<BR>
0128 A new class <TT>G4hMultipleScattering</TT> has been created to provide faster
0129 simulation of hadron transport. This class uses the same multiple scattering
0130 model configured to reduce step limitation. It is used for hadrons and ions
0131 in most physics lists.<BR>
0132 A new module polarization is introduced for simulation of circular polarized
0133 beams of <TT>e+-</TT> and <TT>gamma</TT>.<BR>
0134 The change in response of calorimeters, due to the revision of the
0135 multiple scattering process (in its default configuration) is expected
0136 to be less than 1%. Larger differences are seen in the revised
0137 configuration, which does not apply most step limitations for electons and
0138 that is used in the QGSP_EMV physics list.

0143 Reviewed coherent elastic scattering processes: data tables are now computed
0144 on-flight and the G4ELASTIC data set is no longer necessary.<BR>
0145 New data sets are required for this release, see details below.
0146
0147 <P> </P>
0148 <B>Physics Lists</B>
0149 <P> </P>
0150 The physics list module has been moved inside the <TT>source</TT> tree; as
0151 such it is now built as part of the kernel libraries by default. The number of
0152 libraries has been reduced to two; it is now possible to use them together
0153 with shared libraries (or DLL on Windows) and global libraries.

0284 <LI>Minimum steplimit in 8.1: <TT>tlimitmin = max(lambda/25,

0286 Now: <TT>tlimitmin = max(lambda/25, 1.01*stepmin)</TT><BR>
0287 where <TT>stepmin ~ lambda elastic</TT>.</LI>
0288 <LI>Introduced possibility to have extreme small step(s) before

0290 activated by setting the data member <TT>skin</TT> to a
