红帽从Red Hat 9.0开始，把产品线拆开，分为企业版Linux和社区Linux。

Red Hat Linux 7.1, 7.2, 8, 9:
---> RHEL 2.1, 3, 5, 6, 7
---> Fedora

RHEL：
Enterprise-targeted operating system
Focused on mature open source technology
18-24 month release cycle
Certified with leading OEM and ISV products

Fedora and EPEL：
Red Hat sponsored open source project
Focused on latest open source technology
Rapid 4 to 6 month release cycle
Red Hat does not provide formal support

2014 年，红帽公司收购了 CentOS。
CentOS 6 于 2020 年 11 月 30 日终止
CentOS 8 于 2021 年 12 月 31 日终止
CentOS 7 的支持将一直延续到2024年6月30日

The CentOS Project 的重心已经从 CentOS Linux 转向 CentOS Stream：
Continuously delivered distro that tracks just ahead of Red Hat Enterprise Linux (RHEL) development, positioned as a midstream between Fedora Linux and RHEL. For anyone interested in participating and collaborating in the RHEL ecosystem, CentOS Stream is your reliable platform for innovation.(切记，CentOS Stream是一个作为 RHEL 中游的滚动发行版，并不太建议在生产环境中使用)
