+# Release Notes
+
+## 0.14.0
+
+### Breaking Changes
+
+- Previously, the model specification in the guardrails configuration file, `config.yml`, supported `model_name` as a top-level field.
+  In this release you must specify the model name in the `model` top-level field or as `model` or `model_name` in
+  the parameters field.
+
+  Before:
+
+  ```yaml
+  models:
+    - type: main
+      engine: nim
+      model_name: meta/llama-3.1-8b-instruct
+  ```
+
+  After:
+
+  ```yaml
+  models:
+    - type: main
+      engine: nim
+      model: meta/llama-3.1-8b-instruct
+  ```
+
+  For more information, refer to [pull request #1084](https://github.com/NVIDIA/NeMo-Guardrails/pull/1084).
