-// NOTE: CAS_VERSION_DEVELOPMENT macro is defined via command line in contrast to OCC_VERSION_DEVELOPMENT
-// which is specified in the Standard_Version.hxx
+// NOTE: Since version 6.7.0 OCC_VERSION_DEVELOPMENT macro in the Standard_Version.hxx
+// points to the development status of the OCCT version: for example "dev", "alpha",
+// "beta", "rc1", etc.
+// OCC_VERSION_MAJOR, OCC_VERSION_MINOR and OCC_VERSION_MAINTENANCE macros
+// specify actual (final) version number; for development version it is a future
+// target version number (i.e. version number is incremented immediately after
+// releasing of the stable version).
