Versions of formats have been changed (11 for BinOCAF, 10 for XmlOCAF, 4 for BRep Shape and 3 for Binary BRep Shape).
Files written with the new version will not be readable by applications of old versions.
@subsection upgrade_occt760_poly Changes in *Poly* package and *Poly_Triangulation* class:
* Poly_Triangulation: Replaced all arrays with NCollection_Vector.
* Poly_Triangulation: Old fashion of data access via getting collection reference is not more allowed for safety reasons.
Instead of old API, data access is organized via getters of single element by index.
* New class Poly_Element that allows to store triangles or quads (quad consists of two triangles).
* New class Poly_Mesh is extension of Poly_Triangulation that allows to store mesh with quad polygons as table of Poly_Element.
* New OCAF attribute TDataXtd_SurfacicMesh that allows to store Poly_Mesh in OCAF documents.
