⚠️ Breaking Changes

• [OPERATOR] The default leader election resource lock of gardener-extension-os-ubuntu has been changed from configmapsleases to leases. (#49, @ialidzhikov)
  • Please make sure, that you had at least gardener-extension-os-ubuntu@v1.11 running before upgrading to v1.12.0, so that it has successfully required leadership with the hybrid resource lock (configmapsleases) at least once.

✨ New Features

• [OPERATOR] It is now possible to specify the leader election resource lock via the chart value leaderElection.resourceLock (defaults to leases). (#49, @ialidzhikov)

🐛 Bug Fixes

See https://kubernetes.io/docs/tasks/administer-cluster/dns-debugging-resolution/#known-issues for more details about the issue. (#51, @vpnachev)
