<br>
I am happy to announce Kata Containers 1.4.0 release. It comes with<br>
several nice new features and many bug-fixes. All users are<br>
recommended to upgrade.<br>
<br>
The 1.4.0 release highlights following features:<br>
<br>
- Host cgroups support: qemu process and vcpu threads are now put in<br>
proper cpu cgroup in the host and cpu quota and period are used to<br>
constrain them.<br>
<br>
- NEMU `virt` machine type support: The new machine type is specially<br>
optimized for cloud environments and thus a great fit for Kata<br>
Containers use case. For more information about NEMU, see<br>
<a href="https://github.com/intel/nemu" rel="noreferrer noreferrer" target="_blank">https://github.com/intel/nemu</a>.<br>
<br>
- New NetInterworkingModel `none`: It works with tap endpoint types so<br>
that enlightened CNI plugins can add tap devices to a sandbox<br>
directly, bypassing host network namespaces and thus provide better<br>
performance with less network setup complexity.<br>
<br>
- New NetInterworkingModel `tcfilter`: Yet another method for Kata<br>
Containers to bridge the host netns veth and guest tap device, with TC<br>
filter rules. With it, Kata Containers have better compatibility with<br>
different network endpoint types.<br>
<br>
- Enable macvlan and ipvlan network support: These two networking<br>
models provide lightweight and fast access to underlay or host<br>
interfaces without NATTing.<br>
<br>
- Guest rootfs image can now have a `guest_hook_path` to save a bunch<br>
of prestart/poststart/prestop/poststop hook binaries, and they will be<br>
executed in the guest at specified container life cycle point<br>
accordingly.<br>
<br>

Kudos to all Kata community members for making it happen!<br>
<br>
Cheers,<br>
