159<H2>6. Items for migration of the user code</H2>
160
161Some minor migrations may be necessary for advanced uses of features in Geant4 in
162order to upgrade from release 7.0 to release 7.1, a full recompilation and/or
163reinstallation of libraries and user applications is anyhow required.

168Some installation flags have been introduced or slightly modified:
169<UL>
170<LI><TT>G4LIB_BUILD_ZLIB, G4LIB_USE_ZLIB</TT>: building the <TT>zlib</TT> file compression
171    module has now become optional. It is not required on UNIX-like platforms where the
172    built-in <TT>zlib</TT> library is used, while it is optional on Windows where it is
173    disabled by default.</LI> 
174<LI><TT>G4LIB_BUILD_G3TOG4, G4LIB_USE_G3TOG4</TT>: now required to build and use the optional

184<P> </P>
185<B>User defined solids</B>
186<P> </P>
187User codes which include implementations of customised solids are required to slightly

269    <UL>
270    <LI>The photon processes (<TT>G4PhotoElectric</TT>, <TT>G4ComptonScattering</TT>,
271        <TT>G4GammaConversion</TT>) and <TT>G4eplusnAnnihilation</TT> have been redesigned
272        according to the process-model approach, like for the energy loss processes.<BR>
273        The common base classes, <TT>G4VEmProcess</TT> and <TT>G4VEmModel</TT>, have been
274        consequently upgraded. Physics results should be unchanged.<BR>
275        The redesign is transparent to the user. 'Old' photon and positron processes have
276        been frozen and kept for a while, under <TT>G4PhotoElectric52</TT> ... etc ...
277        See the class <TT>PhysListEmG4v52</TT> in most of extended/electromagnetic
278        examples and <TT>g4v52</TT> alternative PhyicsList in
279        physics_list/electromagnetic.</LI>
280    <LI>The class <TT>G4EmCalculator</TT> allows to access most of the basic quantities of
281        electromagnetic processes: crossSections, meanFreePath, stoppingPower, csdaRange.
282        It has been updated and can be applied to all standard processes.
283        See examples in extended/electromagnetic <TT>RunAction</TT> for TestEm1, TestEm5
284        and TestEm11.</LI>
285    <LI>The limit of applicability of the model of energy loss straggling
286        (<TT>G4UniversalFluctuation</TT>) has been reviewed and extended to smaller energy
287        loss (~eV). This affects energy loss distributions for small steps (under
288        micrometer).</LI>
289    <LI>The <TT>G4EmCorrections</TT> class has been introduced to provide corrections to
290        energy loss of hadrons and ions. With the standard package, stopping power for
291        protons and alpha particles are within 2% with the Nist data, from <TT>1 keV</TT>
292        to <TT>100 GeV</TT> for all atoms.</LI>

294<LI><B>Muons</B>
295    <UL>
296    <LI>A new class <TT>G4EnergyLossForExtrapolator</TT> has been introduced. This class
297        provides calculation of average energy loss and its dispersion for the step of
298        charged particles in media. It also provides average angle of multiple scattering.
299        This class is working independently of the Geant4 event loop and does not require
300        Run, Event and Stepping managers. It requires only particles and materials
301        instantiation.</LI>

305    <LI>Two new models <TT>G4BetheBlochNoDeltaModel</TT> and <TT>G4BraggNoDeltaModel</TT>
306        are released; they can be used for the simulation of exotic heavy ionizing objects
307        (monopoles ..etc..).</LI>

322    with proper decay table. Also issueing a warning message if a shortlived primary

358    <LI>Added optional boolean argument <TT>propagate</TT> to <TT>GetMass()</TT>
359        to avoid propagation of computation of masses to the daughter volumes on

361    <LI>Extended signatures for <TT>OpenGeometry()</TT> and <TT>CloseGeometry()</TT>
362        to consider local optimisation of a subtree of volumes. Voxelisation can now
