Coder 1.21 introduces a new networking model that ensures end-to-end encryption, reduces latency, and improves round-trip performance between users and workspaces. The latest version also includes SSH Connection Caching for faster workspace access, a refreshed workspace providers page with simplified management flow, the ability to cancel workspace builds from the dashboard, support for RStudio IDE, and an installation guide for OpenShift. Future releases will add more workspace provider types beyond Kubernetes.
