Red Hat Enterprise Linux版本8和9
Red Hat了解生命周期规划对我们的客户、合作伙伴、ISV和Red Hat Enterprise Linux生态系统的重要性。随着Red Hat Enterprise Linux版本8的推出，Red Hat将RHEL产品阶段从四个简化为三个：完全支持、维护支持和延长使用寿命阶段。我们还提供了有关预期发布日期和将提供扩展支持的小版本的信息。 Red Hat Enterprise Linux版本8和9提供了十年的生命周期，分为全面支持和维护支持阶段，然后是延长生命周期阶段。此外，Red Hat Enterprise Linux 8和9的客户可以购买名为扩展生命周期支持（ELS）的年度附加订阅，以将有限的订阅服务扩展到维护支持阶段之后。
