After a week in sunny Southern California, KubeCon North America 2021 is a wrap in Los Angeles. For many of us, KubeCon was the first in-person event we have attended since the start of the pandemic. Though this year, KubeCon is a hybrid event even if you missed the in-person talks, you can still catch the virtual talks online. Compared to KubeCons of years gone by, the event has been scaled back slightly to respect social distancing and slowly easing folks back into in-person conferences.

Welcome to the Cloud 66 Changelog. These are the changes that have gone out this month.

It also comes with needrestart enabled by default for automated daemon restarts after applying library updates. In addition, the latest development cycle brings native, certified drivers for NVIDIA vGPU software on Ubuntu 20.04 LTS and 18.04 LTS, fully supporting sophisticated AI/ML workloads. Ubuntu Server 21.10 will be supported by Canonical until July 2022.

14 October 2021: Today, Canonical released Ubuntu 21.10 – the most productive environment for cloud-native developers and AI/ML innovators across the desktop, devices and cloud. “As open source becomes the new default, we aim to bring Ubuntu to all the corners of the enterprise and all the places developers want to innovate,” said Mark Shuttleworth.
