This release updates Kubernetes to v1.18.12 and addresses a critical bug present in the following releases:
- v1.19.3+k3s2
- v1.18.10+k3s2
- v1.17.14+k3s1
- v1.17.13+k3s2
This release is for the v1.18.x release train. Releases addressing this bug are also available for the 1.17.x and 1.19.x release trains. If you are on any of the affected versions, it is recommended that you upgrade.
The critical bug can lead to objects being removed unexpectedly from K3s's database. When this occurs, these objects will no longer be available in the Kubernetes API. See k3s-io/kine#61 for more details.

Changes since v1.18.10+k3s2:
- Fix critical database bug (see above)
- Upgrade Kubernetes to v1.18.12
- Improved SELinux support #2240
containerd has been fixed to relabel /dev/shm which addresses an issue that prevented Envoy proxy from working on SELinux enforcing systems
