+## 0.7
+v0.7 brings many major features. The community works together to refactor the internal code base to bring an unified IR code structure with a unified IRModule, type system and pass infrastructure. We have also bought many exciting new features, some highlights include:
+
+* Initial automatic scheduling support
+* Initial command line driver interface
+* WebGPU and webassembly support
+* Better first class rust support in the codebase
+* Intial Hexagon support
+* Bring your own codegen (BYOC) support
+
+The community also continues to bring high quality improvements to the existing modules including, but not limited to: better frontend coverage, performance, quantization, uTVM and dynamic shape support.
