 ------------------
 
 * When using ``simulate`` with ``TTNxGate`` algorithm, the initial partition is obtained using NetworkX instead of KaHyPar by default. This makes setup easier and means that ``TTNxGate`` can now be used when installing from PyPI. KaHyPar can still be used if ``use_kahypar`` from ``Config`` is set to True.
+* Updated pytket version requirement to 1.27.
 
 0.6.0 (April 2024)
