{: #1162_1514-master}
| Component | Previous | Current | Description |
|---|---|---|---|
| Calico | v3.8.2 | v3.9.2 | See the Calico release notes{: external}. |
| CoreDNS | 1.3.1 | 1.6.2 | See the CoreDNS release notes{: external}. This update includes the following configuration changes. - CoreDNS now runs 3 replica pods by default, and the pods prefer to schedule across worker nodes and zones to improve cluster DNS availability. If you update your cluster to version 1.16 from an earlier version, you can configure the CoreDNS autoscaler to use a minimum of 3 pods. \n - CoreDNS caching is updated to better support older DNS clients. If you disabled the CoreDNS cache plug-in, you can now re-enable the plug-in. \n - The CoreDNS deployment is now configured to check readiness by using the ready plug-in. \n - CoreDNS version 1.6 no longer supports the proxy plug-in, which is replaced by the forward plug-in. In addition, the CoreDNS kubernetes plug-in no longer supports the resyncperiod option and ignores the upstream option. |
