From e6e80fcfd6c478231ac8ef9d2ec647da860252b6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Thu, 17 Sep 2020 16:50:47 +0100 Subject: [PATCH] docs: simplify and clarify the platform support rules MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The distinction between short life and long life Linux distributions turned out to be redundant. 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.
