Version 0.6.0

New Features

• C++17 required
• Gather/Scatter for persistent particle communication buffers added
• Grid-based particle generation, in addition to generalization of random particle generation
• ParticleList with field type tags and thread-level particle interfaces added
• Semi-structured hypre interface for multi-variate systems
• New interface to modify an existing Verlet neighbor list
• New benchmarks for grid halo and particle-grid interpolation

Bug Fixes and Improvements

• Breaking change: replace Slice::{R->r}ank and Slice::{rank->viewRank}()
• Fixed boundary index space bug for Node, Face, and Edge entities causing out of bounds indexing
• Added SYCL support for heFFTe
• Removed use of Kokkos deprecated features: View::Rank and parallel_reduce() on raw pointers
• Run benchmarks and examples with default or default host backends
• Added Kokkos profiling regions
• Added python utilities to plot benchmark results

Deprecated features

• Deprecated Cajita in favor of Cabana::Grid
• Deprecated Kokkos DeviceType class templates in favor of Kokkos MemorySpace
• Deprecated Grid Halo and Partitioner compatibility wrappers

Minimum dependency version updates

• Kokkos minimum 3.7 (previously 3.2)
• Optional dependency heFFTe minimum 2.3 (previously 2.1)
• Optional dependency googletest minimum 1.10 (previous internal download removed)

Experimental Features (subject to change in future releases)

• Distributed particle output with HDF5 library interface
• Expanded sparse grid capabilities: index spaces, local grid, array, and halo
