# 0.6.0
* Introduced `pylops_mpi.optimization.eigs.power_iteration` to estimate the maximum eigenvalue.
* Added `pylops_mpi.optimization.sparsity.ista` and the corresponding `pylops_mpi.optimization.cls_sparsity.ISTA` class, implementing the iterative shrinkage-thresholding algorithm.
* Added `pylops_mpi.optimization.sparsity.fista` and the corresponding `pylops_mpi.optimization.cls_sparsity.FISTA` class, a fast variant of ISTA.
* Included tutorial: "Reflectivity Inversion - 3D", with separate implementations for base, CuPy, and NCCL.
* Added `empty_like` function to `pylops_mpi.DistributedArray` and `pylops_mpi.StackedDistributedArray`.
* Introduced a `vdot` parameter in the `dot` method of `pylops_mpi.DistributedArray` and `pylops_mpi.StackedDistributedArray` to support vector dot products.

# 0.5.0
* Performed fixes to support `numpy>=2.4`.
* Added `redistribute` function to `pylops_mpi.DistributedArray`.
