 # Changelog
 
+## Version 0.31.0
+
+Released November 2, 2023
+
+### Summary
+
+This release contains several documentation improvements and some new additions. Quantum subspace expansion (QSE) is added to the user guide (thanks @bubakazouba). Thanks to our first time contributors @dubeyPraY for a new tutorial on using PennyLane and Mitiq in calculating the energy landscape of a simple variational circuit and @kozhukalov for adding the PEC noise level and calculated error to the calibration logs. **We also removed support for python 3.8**.
