 ### New features since last release
 
 * Add `mid-circuit measurements` support to `lightning.gpu`'s single-GPU backend.
   [(#931)](https://github.com/PennyLaneAI/pennylane-lightning/pull/931)
 
-* Add Matrix Product Operator (MPO) for all gates support to `lightning.tensor`. Note current C++ implementation only works for MPO sites data provided by users.
-  [(#859)](https://github.com/PennyLaneAI/pennylane-lightning/pull/859)
-
-* Add shot measurement support to `lightning.tensor`.
-  [(#852)](https://github.com/PennyLaneAI/pennylane-lightning/pull/852)
-
-* Build and upload Lightning-Tensor wheels (x86_64, AARCH64) to PyPI.
-  [(#862)](https://github.com/PennyLaneAI/pennylane-lightning/pull/862)
-  [(#905)](https://github.com/PennyLaneAI/pennylane-lightning/pull/905)
+* Integrate Lightning-GPU with Catalyst.
+  [(#928)](https://github.com/PennyLaneAI/pennylane-lightning/pull/928)
 
 * Add `Projector` observable support via diagonalization to Lightning-GPU.
   [(#894)](https://github.com/PennyLaneAI/pennylane-lightning/pull/894)
 
 * Add 1-target wire controlled gate support to `lightning.tensor`. Note that `cutensornet` only supports 1-target wire controlled gate as of `v24.08`. A controlled gate with more than 1 target wire should be converted to dense matrix.
   [(#880)](https://github.com/PennyLaneAI/pennylane-lightning/pull/880)

 * Remove support for Python 3.9.
   [(#891)](https://github.com/PennyLaneAI/pennylane-lightning/pull/891)
 
 ### Improvements
 
+* Update the `lightning.tensor` Python layer unit tests, as `lightning.tensor` cannot be cleaned up like other state-vector devices because the data is attached to the graph. It is recommended to use one device per circuit for `lightning.tensor`.
+  [(#971)](https://github.com/PennyLaneAI/pennylane-lightning/pull/971)

 *  Fix PTM stable-latest.
   [(#961)](https://github.com/PennyLaneAI/pennylane-lightning/pull/961)
 
 * Update `README.rst` installation instructions for `lightning.gpu` and `lightning.tensor`.
   [(#957)](https://github.com/PennyLaneAI/pennylane-lightning/pull/957)
 
-* Optimize `GlobalPhase` and `C(GlobalPhase)` gate implementation in `lightning.gpu`.
-  [(#946)](https://github.com/PennyLaneAI/pennylane-lightning/pull/946)

 * Optimize the cartesian product to reduce the amount of memory necessary to set the StatePrep with LightningTensor. 
   [(#943)](https://github.com/PennyLaneAI/pennylane-lightning/pull/943)
 
 * The `prob` data return `lightning.gpu` C++ layer is aligned with other state-vector backends and `lightning.gpu` supports out-of-order `qml.prob`.
-    [(#941)](https://github.com/PennyLaneAI/pennylane-lightning/pull/941)

+  [(#941)](https://github.com/PennyLaneAI/pennylane-lightning/pull/941)
 
 * Add zero-state initialization to both `StateVectorCudaManaged` and `StateVectorCudaMPI` constructors to remove the `reset_state` in the python layer ctor and refactor `setBasisState(state, wires)` in the C++ layer.
   [(#933)](https://github.com/PennyLaneAI/pennylane-lightning/pull/933)

 * The `generate_samples` methods of lightning.{qubit/kokkos} can now take in a seed number to make the generated samples deterministic. This can be useful when, among other things, fixing flaky tests in CI.
   [(#927)](https://github.com/PennyLaneAI/pennylane-lightning/pull/927)
