How do you get security advisories?

Recently I was reading logs on production machine and have seen line

"pdns-recursor[2169088]: PowerDNS Security Update Mandatory: Upgrade now, see https://doc.powerdns.com/recursor/security-advisories/powerdns-advisory-2022-01.html"

I do not have any automatics to get important stuff from my logs, but this is another big question.

I have asked myself - is there any way to get security advisories in RSS-like fashion? Especially for PowerDNS I see only two options how to get them: webpage[1] and reading logs. Both those options are not such convenient as getting newsletter or even RSS.

Maybe you do know any services to get security advisories in RSS reader or at least by email subscription?
