Release notes
Open source →What's Changed
The main change for this release is that the eBPF attachment is now being done by the shim again instead of the node daemonset. This makes the shim less dependent on the node component. It was initially delegated to the node component since loading eBPF programs caused significant memory allocations in the shim but with this new implementation this was addressed by doing the attachment in a separate short-lived shim process. For upgrading to this release, the order does not matter since the node component can still take over the attachment if older shim versions are detected that don't support it.

- cleanup of old migration resources: migration resources are now owned by the source/destination pod, resulting in automatic cleanup by the API Server on deletion of a pod. If this is undesired, for example while debugging, the cleanup can be disabled by setting the flag
-auto-gc-migrations=falseon the manager. - cleanup of old checkpoint images: checkpoint images were not being cleaned up in all cases, especially when migration was disabled.
- various fixes and improvements for migration scalability.

Open source →What's Changed
While validating the latest release on different systems, an issue was identified where the
socket_trackermap would be emptied by the kernel sporadically. This includes a hotfix for this issue by changing the BPF map type.Upgrade notes
If you are coming from release
v0.8.0or earlier and make use of scale to zero, ensure to re-schedule all pods using zeropod after updating thezeropod-nodeDaemonSet. This is due to an architectural change in the socket tracker. Pods running pre-v0.9.0zeropod shims might not be able to detect the last TCP connection and will simply scale down after the configured duration is up.Changelog
- fix: use non-LRU map type for socket tracker by @ctrox in #119
- chore: update image versions by @ctrox in #120
