 ## Breaking changes
 
+- The ODES solver was removed due to compatability issues. Users should use IDAKULU, Casadi, or JAX instead. ([#3932](https://github.com/pybamm-team/PyBaMM/pull/3932))
 - Integrated the `[pandas]` extra into the core PyBaMM package, deprecating the `pybamm[pandas]` optional dependency. Pandas is now a required dependency and will be installed upon installing PyBaMM ([#3892](https://github.com/pybamm-team/PyBaMM/pull/3892))
 - Renamed "have_optional_dependency" to "import_optional_dependency" ([#3866](https://github.com/pybamm-team/PyBaMM/pull/3866))
 - Integrated the `[latexify]` extra into the core PyBaMM package, deprecating the `pybamm[latexify]` set of optional dependencies. SymPy is now a required dependency and will be installed upon installing PyBaMM ([#3848](https://github.com/pybamm-team/PyBaMM/pull/3848))

-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Users can install `scikits.odes <https://github.com/bmcage/odes>`__ to utilize its interfaced SUNDIALS ODE and DAE `solvers <https://docs.pybamm.org/en/latest/source/api/solvers/scikits_solvers.html>`__ wrapped in PyBaMM.
-
-.. note::
-
-   Currently, only GNU/Linux and macOS are supported.
-
-.. note::
-
-   The ``scikits.odes`` solver is not supported on Python 3.12 yet. Please refer to https://github.com/bmcage/odes/issues/162.
-   There is support for Python 3.8, 3.9, 3.10, and 3.11.
-
-.. tab:: Debian/Ubuntu
-
-   In a terminal, run the following commands:
-
-   .. code:: bash
-
-      sudo apt-get install libopenblas-dev cmake
-      pybamm_install_odes
-
-   This will compile and install SUNDIALS for the system (under ``~/.local``), before installing ``scikits.odes``. (Alternatively, one can install SUNDIALS without this script and run ``pip install pybamm[odes]`` to install ``pybamm`` with ``scikits.odes``.)
-
-.. tab:: macOS
-
-   In a terminal, run the following command:
-
-   .. code:: bash
-
-      brew install openblas gcc gfortran cmake
-      pybamm_install_odes
-
-The ``pybamm_install_odes`` command, installed with PyBaMM, automatically downloads and installs the SUNDIALS library on your
-system (under ``~/.local``), before installing `scikits.odes <https://scikits-odes.readthedocs.io/en/stable/installation.html>`__ . (Alternatively, one can install SUNDIALS without this script and run ``pip install pybamm[odes]`` to install ``pybamm`` with `scikits.odes <https://scikits-odes.readthedocs.io/en/stable/installation.html>`__)
-
-To avoid installation failures when using ``pip install pybamm[odes]``, make sure to set the ``SUNDIALS_INST`` environment variable. If you have installed SUNDIALS using Homebrew, set the variable to the appropriate location. For example:
-
-.. code:: bash
-
-   export SUNDIALS_INST=$(brew --prefix sundials)
-
-Ensure that the path matches the installation location on your system. You can verify the installation location by running:
-
-.. code:: bash
-
-   brew info sundials
-
-Look for the installation path, and use that path to set the ``SUNDIALS_INST`` variable.
-
-Note: The location where Homebrew installs SUNDIALS might vary based on the system architecture (ARM or Intel). Adjust the path in the ``export SUNDIALS_INST`` command accordingly.
-
-To avoid manual setup of path the ``pybamm_install_odes`` is recommended for a smoother installation process, as it takes care of automatically downloading and installing the SUNDIALS library on your system.
