 ### Deprecated
 
 ### Removed
 
 ### Fixed
 
-- `ncon` can be differentiated with Zygote, including networks with traces.
-- `ncon` accepts traces in networks whose index lists are given as row matrices, e.g. `[1 1 -1]`.
-- Contractions using the `StridedBLAS` backend no longer heap allocate a view of an input tensor when an allocator such as Bumper's is used ([#273](https://github.com/QuantumKitHub/TensorOperations.jl/issues/273)).

+
+### Added
+
+- `cuTENSORBackend` accepts a `workspace` keyword (`:min`, `:default` or `:max`) to set cuTENSOR's workspace preference for contractions ([#318](https://github.com/QuantumKitHub/TensorOperations.jl/pull/318)).
+
+### Changed
+
+- Compat with GPUArrays is extended to include 12, and with JLArrays to include 0.4 ([#313](https://github.com/QuantumKitHub/TensorOperations.jl/pull/313)).
+
+### Fixed
+
+- `ncon` can be differentiated with Zygote, including networks with traces ([#314](https://github.com/QuantumKitHub/TensorOperations.jl/pull/314)).
+- `ncon` accepts traces in networks whose index lists are given as row matrices, e.g. `[1 1 -1]` ([#314](https://github.com/QuantumKitHub/TensorOperations.jl/pull/314)).
+- Contractions using the `StridedBLAS` backend no longer heap allocate a view of an input tensor when an allocator such as Bumper's is used ([#273](https://github.com/QuantumKitHub/TensorOperations.jl/issues/273), [#314](https://github.com/QuantumKitHub/TensorOperations.jl/pull/314)).
+- `BufferAllocator` now records the full buffer size a pass needs when it overflows its limit, so it no longer under-sizes the buffer on resize and fits everything on the next pass ([#310](https://github.com/QuantumKitHub/TensorOperations.jl/pull/310)).
+- The ChainRules, Enzyme and Mooncake rules cover `tensorfree!(C)` and `tensorfree!(C, allocator)`; the ChainRules rule previously had the wrong signature ([#321](https://github.com/QuantumKitHub/TensorOperations.jl/pull/321)).
 
 ### Performance
 
-- `ncon` has significantly less overhead: the network analysis and contraction tree construction are type stable, and every pairwise contraction goes through a single dynamic dispatch.
-- Contractions of `Array`s that require a permuted copy of an input no longer suffer from a type instability.
-- Index labels given as vectors, as in `ncon` or the method syntax `tensorcontract(IC, A, IA, B, IB)`, are converted to index permutations in a type-stable manner, which avoids compiling the conversion for every combination of numbers of indices.
-- `ncon` partitions its intermediates as `(open indices of A; open indices of B)` instead of placing all indices in the codomain, which avoids repartitioning copies for tensor types such as `TensorMap`s with symmetries ([#311](https://github.com/QuantumKitHub/TensorOperations.jl/issues/311)).
