+# tdc v0.1.4
+
+This release makes the tdc command line easier to discover and use consistently from terminals, scripts, and agents. Running `tdc` without a command now returns a compact AWS-style two-level usage synopsis, while explicit `help`, `--help`, and `--version` requests remain successful. Generated help displays flag value types in angle brackets, lists required flags first, and marks them with `(required)`.
+
+```text
+--db-cluster-name <string> (required)   Starter DB cluster display name
+--project-id <string>                   TiDB Cloud project ID
+```
+
+Filesystem deletion now uses the resource identifier directly without repeating it through a console-style confirmation flag:
+
+```bash
+tdc fs delete-file-system --file-system-name workspace
+```
+
+The release also clarifies the configured value as the default region code, separates human-readable errors from preceding terminal output with a blank line, and keeps the updated contracts covered by unit and binary end-to-end tests.
+
+Upgrade an existing installation with:
+
+```bash
+tdc update --check
+tdc update
+tdc --version
+```
