 ## Features
 
 - Added the `num_steps_no_progress` and `t_no_progress` options in the `IDAKLUSolver` to early terminate the simulation if little progress is detected. ([#5201](https://github.com/pybamm-team/PyBaMM/pull/5201))
+- EvaluateAt symbol: add support for children evaluated at edges ([#5190](https://github.com/pybamm-team/PyBaMM/pull/5190))
 - Added helper functions to import external 3D meshes in PyBaMM ([#5162](https://github.com/pybamm-team/PyBaMM/pull/5162))
 - Added support for algebraic and differential surface form in composite models. ([#5165](https://github.com/pybamm-team/PyBaMM/pull/5165))
 - Adds a composite electrode electrode soh model ([#5160](https://github.com/pybamm-team/PyBaMM/pull/5129))
