Over the next few weeks we're rolling out Fedora Linux 35 to the
`testing` and `stable` streams of Fedora CoreOS. During the Fedora 35
development cycle we followed the Fedora Change process more closely [1]
in order to provide a smoother transition of incoming Fedora Changes.
Current known issues with recent kernels (F34 & F35):
- AWS `m6i` instances fail to boot [2]
- Some OKD [3] and Kubernetes [4] workloads cause kernel deadlock
Some highlights of recently added features:
- cgroups v2 is now the default [5]
- Ignition now supports setting/updating kernel arguments [6]
- DNF Count Me support was added and is now enabled by default [7].
- 64-bit ARM (aarch64) artifacts are now available [8]
- Raspberry Pi 4 install documentation is now available [9]
- systemd-resolved is now fully enabled [10]
Some new features landing in the coming months:
- Support for Virtualbox [11]
- Support for a minimal ISO image [12]
- Support for Nutanix [13]
- Switching to iptables-nft by default [14]
Thanks to everyone who participated in the test day [15] and to everyone that
follows the `testing` and `next` streams to help us identify and fix issues
before they get to `stable`.

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`.
