They can both be covered in a simple way by noting support will target the current release, and the previous release for a period of two years or until its EOL. This rule can also apply to the other UNIX based distros, leaving only Windows needing a different set of rules. This also clarifies that Debian LTS is out of scope, because the LTS support is provided by a separate group from the main Debian maintainer team. Signed-off-by: Daniel P.
