+## New features - Complex & Parallel
+
+- `complex` feature
+  - Implement complex vector, matrix and integral [#35](https://github.com/Axect/Peroxide/issues/35) (Thanks to [@GComitini](https://github.com/GComitini) and [@soumyasen1809](https://github.com/soumyasen1809))
+
+- `parallel` feature
+  - Implement some parallel functions [#72](https://github.com/Axect/Peroxide/issues/72) (Thanks to [@soumyasen1809](https://github.com/soumyasen1809))
+
+## Generic Matrix - MatrixTrait
+
+- Implement `MatrixTrait` for Matrix (Scalar = f64)
+- Implement `MatrixTrait` for ComplexMatrix (Scalar = C64)
+- `LinearAlgebra` and `solve` depend on `MatrixTrait`
+
+## Other changes
