 # Features
 
+- Added verbose logging to `pybamm.print_citations()` and citation tags for the `pybamm.Citations` class so that users can now see where the citations were registered when running simulations ([#2862](https://github.com/pybamm-team/PyBaMM/pull/2862))
 - PyBaMM is now natively supported on Apple silicon chips (`M1/M2`) ([#2435](https://github.com/pybamm-team/PyBaMM/pull/2435))
 - PyBaMM is now supported on Python `3.10` and `3.11` ([#2435](https://github.com/pybamm-team/PyBaMM/pull/2435))
 - Updated to casadi 3.6, which required some changes to the casadi integrator. ([#2859](https://github.com/pybamm-team/PyBaMM/pull/2859))
