Introducing AlmaLinux OS Kitten (AlmaLinux Blog)

The AlmaLinux project has introduced a new edition called 'Kitten',
which will serve as 'the direct upstream for AlmaLinux OS and is
the primary point for the AlmaLinux community to engage and influence
the future of AlmaLinux OS'. Not intended for production use, the
first release is based on CentOS Stream 10 source, which
will eventually be the basis for Red Hat Enterprise Linux (RHEL)
10:

Because we anticipated many changes in 10, we wanted to get a head
start on building AlmaLinux OS 10. Earlier this year we started
setting up infrastructure and the build pipeline for AlmaLinux OS 10,
and started testing using CentOS Stream 10's code. Based on this
preparation work, we are excited to share that we have successfully
built a preview of AlmaLinux OS 10 that we are calling AlmaLinux OS
Kitten 10.

The first Kitten release previews a number of ways that AlmaLinux will
diverge from RHEL 10, including re-enabling frame pointers,
including Simple Protocol for Independent Computing Environments
(SPICE), and adding packages for Firefox and Thunderbird, which have
been dropped from CentOS Stream 10 in favor of Flatpak versions. New
installation images for Kitten will be built quarterly. See the release
notes for download links, installation instructions, and more
information.
