Kubernetes 1.23 is about to be released, and it comes packed with novelties ! Where do we begin ?

This release brings 45 enhancements, on par with the 56 in Kubernetes 1.22 and the 50 in Kubernetes 1.21. Of those 45 enhancements, 11 are graduating to Stable, a whopping 15 are existing features that keep improving, and 19 are completely new.

The new features included in this version are generally small, but really welcomed, like the kubectl events command, support for OpenAPI v3, and gRPC probes. Also, it’s great to see how long-term projects are evolving, like the steady evolution of CSI Drivers, and Windows support.

However, the icing on the cake of this release are all the great features that are reaching the GA state. Grab onto something, the list is intense: CronJobs, IPv4/IPv6 dual-stack support, Ephemeral volumes, and the HPA API, to name a few. We are really hyped about this release!

Not to mention, watch out for all the deprecations and removals in this version!

Kubernetes 1.22 is about to be released, and it comes packed with novelties! Where do we begin ?

This release brings 56 enhancements, an increase from 50 in Kubernetes 1.21 and 43 in Kubernetes 1.20. Of those 56 enhancements, 13 are graduating to Stable, a whopping 24 are existing features that keep improving, and 16 are completely new.

It’s great to see so many new features focusing on security, like the replacement for the Pod Security Policies, a rootless mode, and enabling Seccomp by default.

Also, watch out for all the deprecations and removals in this version!

Kubernetes 1.21 is about to be released, and it comes packed with novelties !

Where do we begin ? This release brings 50 enhancements, up from 43 in Kubernetes 1.20 and 34 in Kubernetes 1.19. Of those 50 enhancements, 15 are graduating to Stable, 14 are existing features that keep improving, and a whopping 19 are completely new.

It’s great to see old features, that have been around as long as 1.4, finally become GA. For example CronJob, PodDisruptionBudget, and sysctl support.

In the same way, it is unfortunate to see the deprecation of security features like Pod Security Policies.

Kubernetes 1.20 is about to be released, and it comes packed with novelties ! Where do we begin ?

As we highlighted in the last release, enhancements now have to move forward to stability or being deprecated. As a result, alpha features that have been around since the early times of Kubernetes, like CronJobs and Kubelet CRI support, are now getting the attention they deserve.

Another noteworthy fact of this Kubernetes 1.20 release is that it brings 43 enhancements, up from 34 in 1.19. Of those 43 enhancements, 11 are graduating to Stable, 15 are completely new, and 17 are existing features that keep improving.

So many enhancements means that they are smaller in scope. Kubernetes 1.20 is a healthy house cleaning event with a lot of small user-friendly changes. For example, improvements in kube-apiserver to work better in HA clusters and reboot more efficiently after an upgrade. Or, being able to gracefully shutdown nodes so resources can be freed properly. It’s exciting to see small features like these paving the way for the big changes that are to come.

Kubernetes 1.19 is about to be released, and it comes packed with novelties.

However, there’s something beyond the features that grabbed our attention this time. Where do we begin?

Kubernetes as a project is maturing, support has been increased from nine to 12 months, and there’s a new protocol in place to ensure a steady progress on feature development. Also, many of its new features are meant to improve the quality of life of its users, like Generic ephemeral inline volumes, or the structured logging.

Of the 34 enhancements in this version, 10 are completely new, eight are graduating to Stable, two are management changes on the Kubernetes project, and the other 14 are existing features that keep improving.
