Enhanced Security for Containers: User namespaces allow pods to run with distinct user IDs inside the container, while mapping them to different IDs on the host. • Better protection against privilege escalation: By enabling user namespaces, it becomes easier to run containers that require root privileges inside the container while being non-root on the host. This improves security by ensuring that any process that escapes a privileged container will not have privileges on the host. Product Manager: Gaurav Singh 9

is now available Red Hat OpenShift Dev Spaces 3.16 is based on Eclipse Che 7.90 Starting from this release, it is possible to configure the container image, temporary storage, memory and CPU limits when starting a CDE using the "Import from Git" flow. With the fuse-overlayfs storage driver, you can enable faster builds and more optimized storage usage for podman build and buildah within your Red Hat OpenShift Dev Spaces cloud development environment (CDE). When you start a CDE from a URL, you are asked if you trust the authors of the repository since creating a workspace from unknown or untrusted sources could be dangerous. Advanced “Import from Git” flow Warning users that creating a CDE from an unknown source could be dangerous Enabling fuse-overlayfs for all workspaces Starting from this release, podman login is performed automatically during workspace startup for all container registries configured in the User Preferences.

reboot To Improve Corruption Protection and Reboot Efficiency • Faster Node Recovery: By detecting and wiping only corrupted layers instead of all images, this feature significantly reduces the time required to reboot nodes after unexpected power failures or crashes. This is particularly valuable in telco edge locations, where minimizing downtime is critical for maintaining service availability. • Improved Resource Efficiency: Cleaning up only corrupted layers reduces the demand for bandwidth and storage, as fewer images need to be repulled. This is especially beneficial in edge environments where network connectivity might be limited, and external registries may not be readily accessible. Product Manager: Gaurav Singh 59
