 These changes are in the Salesforce CLI release candidate. We plan to include these changes in next week's official release. This list isn't final and is subject to change.
 
 ------------
-We hope to see you at [TDX next week](https://www.salesforce.com/tdx/)!
 
-* FIX: We fixed some under-the-hood bugs.
+* NEW: (BETA) We’re thrilled to announce the beta release of Agentforce DX, a set of new Salesforce CLI commands and a Visual Studio Code (VS Code) extension that let you create, preview, and test agents directly in a Salesforce DX project. With Agentforce DX you can:
+
+    * **Generate YAML Spec Files**—Use the `agent generate agent-spec|test-spec` CLI commands to generate simple YAML spec files that describe agents and agent tests.
+    * **Create Agents and Agent Tests**—Pass these spec files as inputs to the `agent create` and `agent test create` CLI commands to create agents and agent tests in your development org.
+    * **Run Agent Tests**—Execute agent tests in your org and view the results from either the VS Code testing panel or by running the `agent test run|results|resume|list` CLI commands.
+    * **Interact with Active Agents**—Interact directly with active agents using the `agent preview` CLI command. (Developer Preview)
+
+    The new CLI commands are in the `agent` topic and are part of the [`@salesforce/plugin-agent`](https://github.com/salesforcecli/plugin-agent) plugin.  Install the plugin with this command:
+
+    ```bash
+    sf plugins install agent
+    ```
+
+    Download and install the VS Code Agentforce DX extension from the [VS Code Marketplace](https://marketplace.visualstudio.com/items?itemName=salesforce.salesforcedx-vscode-agents) or the [Open VSX Registry](https://open-vsx.org/extension/salesforce/salesforcedx-vscode-agents).
+
+    Here are a few examples of what you can do with Agentforce DX.
+
+    Generate an agent spec file that describes your new agent by providing some properties at the command line and be prompted for others; use your default org:
+
+    ```bash
+    sf agent generate agent-spec --type customer \
+          --role "Field customer complaints and manage employee schedules."  \
+          --output-file specs/resortManagerAgent.yaml
+    ```
+
+    Create the agent in your org by passing in the generated spec file:
+
+    ```bash
+    sf agent create --agent-name "Resort Manager" --spec specs/resortManagerAgent.yaml
+    ```
+
+    Generate an agent test spec for testing this new agent; this command is interactive and prompts you for all the information:
+
+    ```bash
+    sf agent generate test-spec
+    ```
+
+    Create an agent test in your org by passing in the generated test spec file:
+
+    ```bash
+    sf agent test create --spec specs/Resort_Manager-testSpec.yaml
+    ```
+
+    Run the agent test in your org:
+
+    ```bash
+    sf agent test run --api-name Resort_Manager_Test
+    ```
+
+    For more information, see:

+    * [_Salesforce CLI Command Reference_: agent Commands](https://developer.salesforce.com/docs/atlas.en-us.sfdx_cli_reference.meta/sfdx_cli_reference/cli_reference_agent_commands_unified.htm)
+
+    We hope you enjoy these fun new commands!
+
+
+    Known Issue: When generating the list of topics in an agent spec, the LLM sometimes includes dashes or other special characters in the topic names. These characters cause errors when creating an agent with the spec. Workaround: Be sure to use only underscores or alphanumeric characters in the topic names; spaces are fine.
+
+## March 5, 2025
+
+Due to [TDX 2025](https://www.salesforce.com/tdx/), we aren't releasing a new stable or stable-rc version today. Hope to see you at the conference!

 * NEW: When you run `project deploy start` with both `--test-level` and `--verbose`, the human-readable output now shows how long each Apex test took to run, in milliseconds. This information was already available in the JSON output. Here's sample output:
 
     ```bash
