Firmware and software update are essential for security and usability among other reasons geared towards smooth usefulness to mostly the end user(s).
Another worthy improvement is to the GitLab Kubernetes agent. This provides a secure connection between a Kubernetes cluster and GitLab. Until now, you could only push to a cluster from the same project where the Kubernetes Agent was registered using the CI/CD Tunnel. In GitLab 14.3, the Agent can be authorized to access entire groups, meaning that every project under the authorized group has access to the cluster without the need to register an agent for every project.
