 # [QuGrad](README.md) Change Log
 
+## Release 1.1.0
+
+This release incorporates the functionality added in [PySTE](https://PySTE.readthedocs.io) v1.1.0:
+
+- Added `evolved_gate_infidelity()` to calculate the gate infidelity of a unitary generated by a system Hamiltonian.
+- Added `evolved_inner_product_all()` to calculate the inner products of a state vector at each time step during its evolution with some fixed vector.
+- Added `evolved_inner_product()` to calculate the inner product of an evolved state vector with some fixed vector.
+- Added `gate_gradient()` to calculate gradients of the average gate infidelity.
+- Added `get_evolution()` to generate the unitary describing the systems' evolution.
+- Added unit tests for these functions.
+- Version pinning requiring `py-ste >= 1.1.0, < 2` has been added.
