      @Deprecated(forRemoval=true) @SubjectToRemoval(date=JUL_01_2025) static final int COORDS_UPDATE
      Deprecated, for removal: This API element is subject to removal in a future version.
      As of Marvin 6.2, no replacement.
      Not supported feature.
      Performs coordinate update during the unbinding of atoms.

      The atom which replaces the unbound atom will take the coordinates of the unbound atom in order preserve the stereo attributes of crossing bonds.
