Hello,
Readline-7.0 was released few months ago and I have rebased it in rawhide to
version 7.0. I have created a compatibility package compat-readline6 to avoid
breaking any existing applications.
Update to readline-7.0 caused a build failure with gdb that was fixed by this
commit [1].
I am providing abidiff report for the changes between readline-6.3 and
readline-7.0 :
