-## Changed
+### Changed
 
 - Map functions in codegen for different usages
 - Move `zink` to the top level
 - Move previous compiler tests to the top level
 - Move examples out of crates
+- The PC order of return and callee labels
+
+#### Fixed
+
+- Add up original PC offset while shifting themselves in PC relocation
+- clean stack on loading data from data section
