--- Comment #4 from igor.v.tsimbalist at intel dot com --- Yes, that's true. It was done deliberately so the libraries get ready for Intel CET, it was reflected in commit message and changelog. The binaries compiled with CET will continue to work on HW without CET support. Why it should not be enabled by default?
