+### Bug fixes 🐛
+
+* Following the 0.21 release of `qiskit-ibm-runtime`, which requires Qiskit 1.0, the PennyLane-Qiskit plugin pins to 
+  `qiskit-ibm-runtime<0.21`. This prevents `pip install pennylane-qiskit` from installing Qiskit 1.0 (via the requirements 
+  of `qiskit-ibm-runtime`), which will break any environments that already have a 0.X.X version of Qiskit installed.
