This is *not* a bug report, but a heads up.  In POV-Ray 3.7, if you set 
reflection and Fresnel on in a #default statement, then later reset the 
#default reflection to zero, you could get away with not turning off 
Fresnel.  POV-Ray 3.8 won't forgive you for that.

Why would one turn on Fresnel in a #default statement?  To put a sheen 
on the stock wood textures, of course!  Illustrations are posted in p.b.i.

OS: openSUSE Leap 15.0 (GNU/Linux)
