SUSE support goes multi-colored off Q4 2021 results Or, to be more particular, when it was transitioned from an OS running in parallel with RHEL to a leading-edge, semi-rolling version of the more stable, licensed, production-ready RHEL OS. Red Hat’s other significant turning point is that RHEL 9 might just draw to a close the absolute class-A public relations SNAFU the company presided over when CentOS was discontinued. Applications in Flatpaks are fully welcomed (the current vogue for immutable Linux distributions takes another step towards mainstream), but RPMs are clearly not going anywhere just yet. To developers, of interest are newer versions of Python (3.9) and GCC (11) by default, plus there are the latest versions of Rust and Go.

There’s also a Podman roll-back capability that detects if new containers won’t start and will quietly replace the new with the (working) old. Red Hat’s official press releases of RHEL version 9 stress the edge capabilities of the OS under the hood, making it easier for organizations to create canonical images that can be rolled out quickly at scale.

Container validation is improved, so there’s less danger of time-poor developers pulling rogue containers from spoofed domains. There are improvements for Red Hat-flavored containers in Podman, and UBI images have been updated in their standard, micro, mini, and init forms.
