Subject: Fedora CoreOS streams rebasing to Fedora Linux 35

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`.

development cycle we [followed the Fedora Change process more closely](https://github.com/coreos/fedora-coreos-tracker/issues/856)
in order to provide a smoother transition of incoming Fedora Changes.

Current known issues with recent kernels (F34 & F35):
