-## v0.4.0
+# CHANGELOG
 
-### ⚠ BREAKING CHANGE
+## [0.4.1] - 2021-08-14
 
-* `BaguaBucketPy::append_decentralized_synchronous_op` now only supports full precision decentralized communication.
+    ### Features
+    
+        - Add opentelemetry to report tensor ready order (#42)
 
-### Features
 
-* make full precision decentralized op stateless (#36) 98319c9
-* add (scatter, gather, scatter_reduce) and all inplace version communication primitives (#37) f931473
-* add native low precision decentralized operator (#26) 50295e8
-* better debug log including tensor info when executing ops 1bd6e0b
+## [0.4.0] - 2021-07-23
