0063 The default RedHat compiler gcc-2.96 distributed in RedHat 7.X is NOT
0064 supported. It has been verified that it produces incorrect binaries,
0065 therefore is not reliable. See also <A HREF="#note-1">note below</A>.</LI>

0120 <UL>
0121 <LI>The default compiler distributed by Red Hat since release 7.0 is
0122 NOT supported and not considered reliable for running a Geant4-based
0123 application. In more than one test case, binaries produced by gcc-2.96
0124 have shown incorrect behavior, either due to wrong order of
0125 initialisation of static data in memory or to bugs in the system
0126 <TT>iostream</TT> classes, problems which apparently have all been
0127 solved in more recent versions of the compiler (3.X series).<BR>
0128 For information, gcc-2.96 is a compiler that has never been

0294 <UL>
0295 <LI>A new command, <TT>/vis/scene/endOfRunAction</TT>, has been implemented.
0296 The default behaviour is "refresh". In the case when
0297 <TT>endOfEventAction</TT> is "accumulate", it causes systems requiring
0298 post-processing, such as DAWN, or file-based systems, such as DAWNFILE
0299 and HepRep, to show the view (equivalent to <TT>/vis/viewer/update</TT>)
0300 at the end of run and screen-based systems, such as OpenGL, to clear the
0301 tracks. hits, etc., at the start of the next run. Usually this is the
0302 desired behaviour.<BR>
0303 The user will find that it is no longer needed to issue
0304 <TT>/vis/viewer/update</TT> (or <TT>/vis/viewer/flush</TT>) at the end
0305 of a run. To revert to the old behaviour, one should issue the command
0306 <TT>/vis/scene/endOfRunAction accumulate</TT>.</LI>
0307 <LI>The OPACS graphics driver has been removed since that graphics
0308 system has been superseded by
0309 <A TARGET="ext" HREF="http://www.lal.in2p3.fr/OpenScientist">OpenScientist</A>.</LI>
0310 <LI>A new HepRep driver has been added, producing files suitable for viewing
0311 with the <A TARGET="ext" HREF="http://wired.freehep.org">WIRED event display</A> (or
0312 other HepRep clients).<BR>
0313 The previous HepRep driver that produced HepRep version 1 files
0314 from <TT>/vis/open HepRepFile</TT> is still supported.
0315 But a new driver producing HepRep version 2 files is now available
0316 from <TT>/vis/open HepRepXML</TT>.<BR>
0317 The newer HepRep format allows the WIRED event display to give you greater
0318 control over visibility of various event and detector components.
0319 It will also set the stage for many improvements to come in later versions
0320 of WIRED (such as the ability to edit and save attribute changes from the
0321 event display client and have these changes apply to subsequent Geant4
0322 images that one reads, and the ability to adjust visibility based on cuts
0323 on attributes such as energy and momentum).<BR>
0324 <TT>/vis/open HepRepXML</TT> provides the following other additional
0325 benefits over <TT>/vis/open HepRepFile</TT>:
0326 <UL>
0327 <LI>More compact files (by better hierarchical handling of repeated
0328 attributes).</LI>
0329 <LI>Ability to save individual events directly to gzipped files.</LI>
0330 <LI>Ability to save multiple events to a single zip file.</LI>
0331 </UL>
0332 For details, see the README in <TT>$G4INSTALL/source/visualization/HepRep</TT>.<BR>
