+Version 0.4.0 (Nov 23, 2024)
++++++++++++++++++++++++++++++
+
+This release adds two new quantum circuit renderers -- one based on matplotlib and another that renders the circuit as text -- and improves the circuit simulation speed.
+
+New features
+------------
+- Add matplotlib-based and text-based quantum circuit renderers. The new rendering framework is more flexible and can be used in different environments without latex dependencies. (`#239 <https://github.com/qutip/qutip-qip/pull/239>`_ and `#244 <https://github.com/qutip/qutip-qip/pull/244>`_ by Rushiraj Gadhvi)
+
+Improvements
+------------
+- `einsum` is used to speed up the circuit simulation by up to 10 times. (`#225 <https://github.com/qutip/qutip-qip/pull/225>`_ by Boxi Li)
+
+
+Miscellaneous
+-------------
+- The QIR support is removed. (`#238 <https://github.com/qutip/qutip-qip/pull/238>`_ by Boxi Li)
+
+Version 0.3.2 (Sept 3, 2024)
+++++++++++++++++++++++++++++
+
+Improvements
+------------
+- Add RZX gate to the SCQubits model. Fix bugs on the ZX strength. (`#245 <https://github.com/qutip/qutip-qip/pull/245>`_)
+- Compile the documentation using qutip v5 (`#246 <https://github.com/qutip/qutip-qip/pull/246>`_)
+
+Bug Fixes
+---------
+- Add phi parameter to expand_operator call. (`#237 <https://github.com/qutip/qutip-qip/pull/237>`_ by Neill Lambert)
+- Fix the warning on MacOS. (`#240 <https://github.com/qutip/qutip-qip/pull/240>`_)
+- Fix a bug in :class:`~.QubitCircuit.add_1q_gate`. (`#250 <https://github.com/qutip/qutip-qip/pull/250>`_ issue raised by hatlabcz Chao Zhou)

 The qutip-qip package used to be a module ``qutip.qip`` under `QuTiP (Quantum Toolbox in Python) <http://qutip.org/index.html>`_. From QuTiP 5.0, the community has decided to decrease the size of the core QuTiP package by reducing the external dependencies, in order to simplify maintenance. Hence a few modules are separated from the core QuTiP and will become QuTiP family packages. They are still maintained by the QuTiP team but hosted under different repositories in the `QuTiP organization <https://github.com/qutip>`_.
 
-The qutip-qip package, QuTiP quantum information processing, aims at providing basic tools for quantum computing simulation both for simple quantum algorithm design and for experimental realization. Compared to other libraries for quantum information processing, qutip-qip puts additional emphasis on the physics layer and the interaction with the QuTiP package. The package offers two different approaches for simulating quantum circuits, one with :obj:`.QubitCircuit` calculating unitary evolution under quantum gates by matrix product, another called :obj:`.Processor` using open system solvers in QuTiP to simulate the execution of quantum circuits on a noisy quantum device.
