-# GroqFlow Known Issues
+# Release Notes
+
+## v4.3.0
+
+### Changes
+
+* Support for SDK 0.11.
+* Add beta support for groq-torch-importer front-end support.
+* Clean up package dependencies.
+* Various bug fixes.
+
+### Known Issues
+
+* Yolo V6 proof point downloads the pytorch weights and invokes the export script to get the ONNX file.
+* Pip install of GroqFlow may complain about incompatible protobuf version.
+
+## v4.2.1
+
+### Known Issues
 
 * Runtime errors due to mismatches in tensor sizes may occur even though GroqFlow checks the data shape. (G14148)
 * Whacky terminal line wrapping when printing groqit error messages. (G13235)
