The change in this behavior in GNU sort(1) was noted when the POSIX standard changed back in 2001 or so. I believe there was a lot of talk around that time about the new behavior. It was known at that time that scripts using the [soon to be] deprecated "sort +N" behavior would [eventually] need to change under GNU coreutils. Looks like they finally broke the compatibility to make the change complete, at least in GNU sort(1). Certainly we can note *that* in the release notes, and if you're able to track down other specific breakages between FC4 and FC5, those would be good candidates for relnotes as well.
