[Unified compiler] Convert to MBQC formalism

doc/releases/changelog-dev.md

@@ -321,6 +321,9 @@
 * Added a `QuantumParser` class to the `qml.compiler.python_compiler` submodule that automatically loads relevant dialects.
   [(#7888)](https://github.com/PennyLaneAI/pennylane/pull/7888)
 
+* A compilation pass written with xDSL called `qml.compiler.python_compiler.transforms.ConvertToMBQCFormalismPass` has been added for the experimental xDSL Python compiler integration. This pass converts all gates in the MBQC gate set (`Hadamard`, `S`, `RZ`, `RotXZX` and `CNOT`) to the textbook MBQC formalism.
+  [(#7870)](https://github.com/PennyLaneAI/pennylane/pull/7870)

 * Enforce various modules to follow modular architecture via `tach`.
