According to the latest tweet published by the @CentOSProject official Twitter account, CentOS 8 is expected to be released on September 24. The development cycle for this release began in May of this year, and it is unclear that CentOS 7.7 will be released on the same day or earlier. CentOS is a Linux distribution that provides a free, community-supported computing platform functionally compatible with its upstream source, Red Hat Enterprise Linux. In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL, under a new CentOS governing board.
The next version of #CentOS is being released September 24 and will be announced in all the usual places.

If CentOS 8 and RHEL 8 have the same life cycle, full support will continue until around May 2424, and maintenance updates will be available until May 2029, meaning there will be a 10-year support period.
