 New features in ``yadg-5.2`` are:
 
-  - Implemented support for merged/appended files in :mod:`~yadg.extractors.eclab.mpr`. Test files taken from the data available at https://zenodo.org/doi/10.5281/zenodo.12165685. Thanks to Arnd Koeppe for bringing the issue up.
-  - Implemented support for the Modular Potentio technique in :mod:`~yadg.extractors.eclab.mpr`. Thanks to Graham Kimbell and Clea Burgel (from Empa) for providing test data.
