+**Enhancements:**
+
+- support for numpy v2.0 and scipy v1.14
+- add MPS sampling: [`MatrixProductState.sample_configuration`](quimb.tensor.tensor_1d.MatrixProductState.sample_configuration) and [`MatrixProductState.sample`](quimb.tensor.tensor_1d.MatrixProductState.sample) (generating multiple samples) and use these for [`CircuitMPS.sample`](quimb.tensor.circuit.CircuitMPS.sample) and [`CircuitPermMPS.sample`](quimb.tensor.circuit.CircuitPermMPS.sample).
+- add basic plot method for SimpleUpdate classes
+- add [`edges_1d_chain`](qumib.tensor.geometry.edges_1d_chain) for generating 1D chain edges
+- [operatorbuilder](quimb.experimental.operatorbuilder): better coefficient placement for long range MPO building
