Sometimes start point of the intersection line is in the surface boundary strictly. I.e. the parameter of this point in the surface can be equal to both 0 or 2*PI equivalently. It is important to chose correct parameter value.
The algorithm of prediction is based on monotonicity property (see CylCylMonotonicity(...) function in IntPatch_ImpImpIntersection_4.gxx). Now, this function is used wrongly. The fix improves this situation.

Various improvements in point-solid classifier:
1) Refactoring.
2) BndBoxTree is extracted into separate class.
3) UB-tree calculation is cashed to improve point-solid classification speed.
4) Ray / curve intersection improved by trimmed parameters and correct order.
5) Fixes in logic.
6) Calculation caching at the classifier level.
3D-claasifier now takes into the account the vertex/edges tolerances. If the given point lays inside the tolerance area of vertex or edge of the solid it's classified as TopAbs_ON.
The behavior of IntCurvesFace_Intersector::Perform was changed. Now it may use optional null-tolerance to classify 2d-point relatively to the given face.
UBTreeFiller is used to speedup intersection process between edges/vertices and the point.
The test case 'boolean gdml_private ZH2' extensively uses the SolidClassifier. After this fix it returns the correct classification statuses, which leads to incorrect result shape (reported by checkshape). Yet the result shape without this fix also seems to be incorrect (one of the isolines goes out of boundary of the face). Thats why it's marked with 'TODO'.
Corrections in test cases.
Test case is added.
1. Check, if value found by math_PSO algorithm cannot be precised by math_NewtonMinimum algorithm. In this case, we call math_PSO algorithm repeatedly, however, with other parameters.
2. Some margin of edge tolerance value has been provided in IntTools_Tools class.
3. Interface of math_NewtonMinimum class has been changed (method GetStatus() has been added).
Correction of some test cases according to their new behavior.
The update of the set of boundary edges has been added for the case when faces containing milti-connected edges are excluded from merging.
Update test cases for unifysamedom to generate snapshots.
The new option AllowInternalEdges has been added in the class ShapeUpgrade_UnifySameDomain. It determines how the algorithm treats the situation when two faces can be merged together but they have connection with another face via the common edge.
With this option turned on, merging of such faces is not stopped, but the multiconnected edges are added to the merged face as INTERNAL edges.
By default it is false. In this mode such merging is forbidden, so the result shape will not contain any new INTERNAL edges.
The behavior of the algorithm has been changed so that it does not merge faces from different shells.
Added protection for cases of the overlapped edges.
Returning value for methods in the LocOpe_SplitShape::AddOpenWire(), LocOpe_SplitShape::AddClosedWire() are modified from void to boolean in order to avoid raising exceptions.
To avoid regression for test case modalg_5 bug25243 tolerance of vertices of the degenerated edges are increased to value of tolerance of the splitting vertex for case when splitting vertex was projected on the degenerated edge.
Command checkplatform was created.
All test cases were updated.
Global variable os_type was eliminated.
New option -osx (MacOS) for procedure checkplatform was added.
For FSAA mode we now store the depth values from first sample in myRaytraceFBO1 and do not modify it while collecting the rest of samples.
When all samples are gathered we fetch color from myRaytraceFBO2 and depth from myRaytraceFBO1 and display it to the current FBO.
Test bugs vis bug27337 added.
1. Check, if edge is same-range, is now made with some tolerance (not strictly) in GeomLib_CheckCurveOnSurface class. Default value of this tolerance is Precision::PConfusion(). However, this value can be changed with corresponding interface.
2. DRAW-command "attachpcurve" has been added to BOPTest_UtilityCommands.cxx file. This command creates p-curve of given edge on given face. It can assign 2D-curve of one of the edge already included in the face or (if it is not possible) rebuilds new 2D-curve.
Creation of test case for this issue.
Adjusting test case boolean volumemaker A8 according to its new behavior on Windows.
Regressions that appeared in OCCT 6.6.0 are fixed.
Correction of test cases for issue #25813
Reference data update for test case bugs/mnodalg_6 /bug25908
1. The reason of the regression is not-closed intersection result. This problem has been solved (in this fix) by adding joint point to the both neighbors intersection lines (lines were extended to the this intersection point). It is made in IntPatch_WLineTool::ExtendTwoWlinesToEachOther(...) method.
2. Interface of IntPatch_PointLine and inherited classes has been changed. Methods ChangeVertex(...) and RemoveVertex(...) have been added.
Test cases for this issue have been created.
Small correction in the code.
1. New sharing algorithm has been implemented. If intermediate point of some edge is included in the tube with center taken in another edge and radius equaled to maximal vertex-tolerance of both edges then these two edges are considered to be shared. This know-how touches edges only, which have common blocks with interfered faces. If they do not have any common-blocks the algorithm will work as before.
2. Interface of BOPAlgo_PaveFiller::IsExistingPaveBlock(...) method has been changed.
Creation of test case for issues #27128 and #27179
Adjusting some test cases according to their new behavior, because they are IMPROVEMENTS really (TODOs have been deleted).

Test case added.
Correction of test case for issue CR27133
OpenGl_ShaderManager::stdComputeLighting() - handle single directional light specifically
for compatibility with broken OpenGL ES drivers.
Added test cases using built-in GLSL shading programs.
When reducing the tolerance values of the vertices put on section curves take into
account all section curves, not only those for which the tolerance have been reduced
(method void BOPAlgo_PaveFiller::CorrectToleranceOfSE()).
The new protection has been added to avoid reducing of tolerance values of vertices
to the values less than the tolerance values of edges containing these vertices.
