Does mshr produce Delaunay triangulated meshes?

Can someone please confirm that mshr generates Delaunay triangulated meshes in 2D?

The documentation of mshr appears to be sparse. I see mention of ‘Delaunay’ in the source code, but I want to make sure.

Thank you in advance for any help.

Mshr uses CGAL and tetgen, so you have to look at their documentation.
For instance, consider:
https://bitbucket.org/fenics-project/mshr/wiki/API/CSGCGALMeshGenerator2D
https://doc.cgal.org/latest/Triangulation_2/index.html
If you look at the source code of the 2D generator, you observe that delauney triangulations are mentioned multiple times.
