freebsd security - May 2019 - Question about FreeBSD-SA-18:10.ip.asc patch information

Hi!

The security advisory FreeBSD-SA-18:10.ip.asc says

"Due to source code differences in FreeBSD 10-stable a patch is not yet
available for FreeBSD 10.4.  This will follow at a later date."

I know that 10.4 is EOL now, but did that ever happen? Perhaps the
advisory should be updated with either a reference to the patch, or a
revised statement?

Thanks in advance!
