1275 28 aug 01: mma
1276- G4MultipleScatteringx: small modifs in BuildPhysicsTable,
1277  ComputeTransportCrossSection, PostStepDoIt.
1278  GetContinuousStepLimit and AlongStepDoIt moved to .cc file
1279
1280 23 aug 01: L. Urban
1281- new angle and z(geom. pathlength) distributions,
1282  energy (step) dependence has been reduced,
1283  Store/Retrieve methods have been commented out temporarily
1284

1286- G4MultipleScatteringx: methods to store/retrieve PhysicsTable
1287
128818 may 01: V.Ivanchenko (utils-V03-01-01)
1289- clean up againist Linux ANSI strict compilation mode.
1290   
129116 may 01: L.Urban (utils-V03-01-00)
1292- value of the member cpar has been changed back to the original
1293  value 1.5 in G4MultipleScattering.cc. The same is done in
1294  G4MultipleScatteringx.cc (the data member name is cparm there).
1295  This change affects all the results for low energy (< 1 MeV
1296  for electrons).
1297 
129815 may 01: L.Urban
1299- new multiple scattering version committed under the class name
1300  G4MultipleScatteringx. It gives better msc angle distribution
1301  than the standard G4MultipleScattering. It uses a distribution
1302  to simulate the geom./true pathlengths (standard : mean values
1303  only) and has a framework implemented in it to perform special
1304  stepping near to a boundary (this algorithm works, but some
1305  further development/tuning needed - this algorithm is disabled
1306  by default). This new version can be used after the change:
1307       G4MultipleScattering  --> G4MultipleScatteringx
1308  in the PhysicsList.
1309     
131027 mar 01: L.Urban (utils-V03-00-06)
1311- another bug fixed in G4VEnergyLoss.cc, in the fluct code.
1312  The code gave in some cases (very rarely) small negative energy loss
1313  for small (~ micrometer) step size, now it is cured.
1314
131523 mar 01: L.Urban (utils-V03-00-05)
1316- bug fixed in fluct in G4VEnergyLoss.cc
1317  Some int internal variables have been changed to doubles,
1318  anomaly at extreme high energy/high cut (zero energy deposit)
1319  is cured.
1320     
132105 mar 01 mma (utils-V03-00-04)
1322- new subdirectory: integral
1323  migration of all G4I.. processes from muons, standard, utils into integral
1324     
132501 feb 01: L.Urban (utils-V03-00-01)
1326- bug fixed in the fluctuation code , in G4VEnergyLoss.cc
1327  This bug affected the width of the energy loss/energy deposit
1328  distribution in the case of small cut value, the distribution
1329  was too narrow....
1330     
133116 jan 01: mma (utils-V03-00-00)
1332- bug fixed in MultipleScattering.cc L.Urban 11-01-01
1333  there was an error in computation of the transport
1334  cross section, the cross section was too small for
1335  low energy (below few MeV for electrons)
1336   
133709 nov 00: mma (utils-V02-00-04)
1338- G4EnergyLossMessenger : subdirectory /process/eLoss created
