-- Tag for release 9.1.p02.
+Jul 07, 2008  V.Grichine                 geom-csg-V09-01-04
+- G4Sphere: fixed bug in DistanceToOut(p, v, ...) for normal 'fSTheta'
+  greater than 90*deg, and use of tangent giving negative value.
+  Completes series of corrections introduced in previous tag.
+

+- G4Tubs: fix in DistanceToIn(p,v, ...) in case of point on surface with
+  very small tangent direction; now returning kInfinity and no longer zero.
+  It fixes rare observed cases of zero value returned by both DistanceToIn()
+  and DistanceToOut(), causing stuck tracks with zero step length.
+
+Jun 20, 2008  V.Grichine
+- G4Sphere: fixed calculation of roots in DistanceToOut(p,v,...) for
+  theta-conical surfaces interserctions and for sTheta<=90 degree intersection.
+  Addresses issue reported when running PET application with optical photons
+  about mis-computation of distance on half-sphere constructs.
+- Updated unit test for sphere.
