# Release v2.4.13 ## Important - **Please review the [v2.4.0 release notes](https://github.com/rancher/rancher/releases/tag/v2.4.0) for important updates/ breaking changes.** - **Kubernetes 1.18 is now the default version [[#25117](https://github.com/rancher/rancher/issues/25117)]** - Kubernetes 1.18 is now the default version. Whenever upgrading to any Kubernetes version, please review the Kubernetes release notes for any breaking changes. - **Users using a single Docker container install** - Etcd in the Docker container has been upgraded from 3.3 to 3.4, therefore you _must_ take a backup before upgrading in order to be able to roll back to a v2.3.x release. You will not be able to rollback without this backup. - **Users using node pools with RHEL/CentOS nodes [[#18065](https://github.com/rancher/rancher/issues/18065)]**: The default storage driver for RHEL/CentOS nodes has been updated to `overlay2`. If your node template does not specify a storage driver, any new node will be provisioned using the new updated default (`overlay`) instead of the old default (`devicemapper`). If you need to keep using `devicemapper` as your storage driver option, edit your node template to explicitly set the storage driver as `devicemapper. - **Users running Windows clusters [[#25582](https://github.com/rancher/rancher/issues/25582)]** - Windows has launched a security patch as of Feb 11. Before upgrading, please update your nodes to include this security patch, otherwise your upgrade will fail until the patch is applied. - **Rancher launched clusters require additional 500MB space** - By default, Rancher launched clusters have enabled audit logging on the cluster. - **Rancher launched Kubernetes clusters behavior of upgrades have changed [[#23897](https://github.com/rancher/rancher/issues/23897)]** - Worker nodes are now upgraded in batches. Please refer to the [RKE documentation](https://rancher.com/docs/rke/latest/en/upgrades/maintaining-availability/) about how to upgrade clusters without downtime for applications. - **Restrict Kubernetes versions in Rancher helm chart to versions less than 1.20.0 [[#30746](https://github.com/rancher/rancher/issues/30746)]** - This restriction was added to prevent Rancher from being installed on incompatible versions of Kubernetes. ## Versions Please refer to the [README](https://github.com/rancher/rancher#latest-release) for latest and stable versions. Please review our [version documentation](https://rancher.com/docs/rancher/v2.x/en/installation/server-tags/) for more details on versioning and tagging conventions. ## Enhancements - Updated to use `v1.18.15-rancher1-1` and `v1.17.17-rancher1-1` - Allow for rancher-agent image to be pulled from cluster private registry. [[#26366](https://github.com/rancher/rancher/issues/26366)] - Add support for configuring OpenLDAP with StartTLS [[#29810](https://github.com/rancher/rancher/issues/29810)] - Add option in the UI to use StartTLS for OpenLDAP [[#30348](https://github.com/rancher/rancher/issues/30348)] - Fixed Logging support for clusters with Windows Server SAC 1909 nodes and for clusters with Windows Server LTSC 2019 nodes. [[#30279](https://github.com/rancher/rancher/issues/30279)] - Logging system chart upgraded to version 0.2.3 [[#30569](https://github.com/rancher/rancher/issues/30569)] - Added disableMountSubPath option to Prometheus operator for monitoring system chart [[#29149](https://github.com/rancher/rancher/issues/29149)] - Added filter option for requests to get a template so that only version links compatible with cluster are returned. [[#30497](https://github.com/rancher/rancher/issues/30497)] - Added new Rancher external DNS system chart. [[#30186](https://github.com/rancher/rancher/issues/30186)] - Enable support for limiting Kubernetes versions of system charts. [[#29647](https://github.com/rancher/rancher/issues/29647)] ## Major Bugs Fixed Since v2.4.12 - Fixed issue with Rancher server pods crashing. [[#28293](https://github.com/rancher/rancher/issues/28293)] ## Minor Bugs Fixed Since v2.4.12 - Fixed `confd` build issue to support Huawei Arm server. [[#30678](https://github.com/rancher/rancher/issues/30678) [PR](https://github.com/rancher/confd/pull/2)] - Added retry on conflict for errors encountered while enabling monitoring. [[#30290](https://github.com/rancher/rancher/issues/30290)] - Fixed an issue where EC2 instances failed to start when using Amazon Linux.

[[#30074](https://github.com/rancher/rancher/issues/30074)] - Rancher’s Istio installation now includes missing helm chart template for setting resource limits and requests on Istio sidecar containers with annotations. [[#28950](https://github.com/rancher/rancher/issues/28950)] ### Air Gap Installations and Upgrades In v2.4.0, an air gap installation no longer requires mirroring the systems chart git repo. Please follow the directions on how to [install Rancher to use the packaged systems chart](https://rancher.com/docs/rancher/v2.x/en/installation/air-gap/install-rancher). ### Known Major Issues - When using monitoring with persistent storage for Grafana enabled, upgrading monitoring causes the pod to fail to start. Workaround steps are provided in the issue. [[#27450](https://github.com/rancher/rancher/issues/27450)] - When using monitoring, upgrading Kubernetes versions removes the _“API Server Request Rate”_ metric [[#27267](https://github.com/rancher/rancher/issues/27267)] - When a new chart version is added to a helm 3 catalog, the upgrade process can default to helm 2, causing an api error. Workaround in issue. [[27252](https://github.com/rancher/rancher/issues/27252)] ## Versions ### Images - rancher/rancher:v2.4.13 - rancher/rancher-agent:v2.4.13 ### Tools - cli - [v2.4.10](https://github.com/rancher/cli/releases/tag/v2.4.10) - rke - [v1.1.14](https://github.com/rancher/rke/releases/tag/v1.1.14) ### Kubernetes - [1.18.15](https://github.com/rancher/hyperkube/releases/tag/v1.18.15-rancher1) (default) - [1.17.17](https://github.com/rancher/hyperkube/releases/tag/v1.17.17-rancher1) ## Upgrades and Rollbacks Rancher supports both upgrade and rollback. Please note the version you would like to [upgrade](https://rancher.com/docs/rancher/v2.x/en/upgrades/) or [rollback](https://rancher.com/docs/rancher/v2.x/en/backups/rollbacks/) to change the Rancher version. Please be aware that upon an upgrade to v2.3.0+, any edits to a Rancher launched Kubernetes cluster will cause all system components to restart due to added tolerations to Kubernetes system components. Plan accordingly. Recent changes to cert-manager require an upgrade if you have an HA install of Rancher using self-signed certificates. If you are using cert-manager older than v0.9.1, please see [the documentation](https://rancher.com/docs/rancher/v2.x/en/installation/options/upgrading-cert-manager/) on how to upgrade cert-manager. **Important:** When rolling back, we are expecting you to rollback to the state at the time of your upgrade. Any changes post upgrade would not be reflected. ---
