# 20210518 Fedora CoreOS Status Fedora 34 rebase email
Over the next two days we're rolling out the first Fedora 34 based
Fedora CoreOS into the `stable` stream.
Some notable issues/configurations:
- Very old systems (Fedora 32 and earlier) may not be able to update [0]
- systemd-resolved is still enabled but not used yet [1]
Here are some highlights of recently added features in Fedora CoreOS:
- The `/boot` partition is now mounted read-only.
- This continues the work to protect more of the OS from accidental damage.
- It is now possible to configure boot disk RAID 1 mirroring via Ignition [2].
- Better introspection into the state of Zincati (the update agent) from `rpm-ostree status`.
- Better support for disk encryption.
- Initial (non-automatic) support for updating the bootloader. [3]
Here are some new features landing in the coming months:
- Support for specifying kernel arguments via Ignition [4].
- Move to cgroup v2 by default [5].
- DNF Count Me support for Fedora CoreOS [6].
Thanks to everyone who participated in the test day [7] and to everyone that
run the `testing` and `next` streams to help us identify and fix issues
before they get to `stable`.
Dusty Mabe, for the Fedora CoreOS team
