It's maybe a little late for 14/15 now. I'm thinking I will send email to gdb@ and push the NEWS patch after the 14 branch is made. That is, deprecate in 15 and remove in 16. I have also been wondering if some of the other debug formats are still relevant. My suspicion is that they are long since obsolete. Tom
