+
+Today, we’re excited to announce the release of Radius v0.54. This update brings several improvements and fixes detailed below. You can find the full release notes on our [GitHub releases page](https://github.com/radius-project/radius/releases/tag/v0.54.0). 
+
+If you’re new to Radius, it’s a cloud-native application platform designed to simplify the deployment and management of Applications. To get started, visit our [getting started guide](https://docs.radapp.io/getting-started/) and learn how to install Radius and create your first app.
+
+## Fixed `rad workspace show` errors when no current workspace exists 
+The `rad workspace show` command has been updated to improve usability. Previously, if no workspace was set, the command would return an error, which could be confusing. With this release, the command now logs an informational message to guide you when no current workspace exists. This change ensures a more user-friendly experience when managing workspaces. For more details, refer to the [CLI documentation](https://docs.radapp.io/reference/cli/rad_workspace_show/). 
+
+## Fixed `rad credential show azure` command 
+A fix has been made to the `rad credential show azure` command. Previously, this command would fail with a runtime error: invalid memory address when attempting to display Azure Service Principal credentials. This issue has been resolved, and the command now correctly displays the Azure credentials you’ve configured for Radius. 
+
+## Upgrading to Radius v0.54
+Upgrading to the latest version is straightforward. First, update your Radius CLI, then run the `rad upgrade kubernetes` command. Note that only incremental version upgrades are supported, so ensure you’re upgrading from the previous version. For detailed instructions, consult the [upgrade documentation](https://docs.radapp.io/guides/operations/kubernetes/kubernetes-upgrade/). 
+
+## New contributors 
+We’re thrilled to welcome new contributors to the Radius community! A special thanks to **@filipevrevez** for their first contribution in [PR #10749](https://github.com/radius-project/radius/pull/10749). Your contributions help make Radius better for everyone.
