Version 1.2

New features:

• Optional JSON input files (main input, material input, and analysis input) and log file (enabled with ExaCA_ENABLE_JSON)
• Optional JSON output files
• Version/commit output functions
• Significant update to analysis routines

Performance:

• Reduced total communication by converting grain ID into separate grain orientation and repeat value which avoids type conversion issues
• Reduce communication buffer sizes from total halo region to the total active communicated cells (plus buffer space)

Deprecated features:

• Problems without remelting with spot arrays and temperature file input
• Plain text input files (main input, material input, and analysis input) and log file

Deprecated feature removal:

• Decomposition strategy as a code input (a 1D domain decomposition in the Y direction is now used for all simulations with multiple MPI ranks)

Bug fixes and improvements:

• Temperature interpolation errors near boundaries
• Nucleation unit test race condition fixed
• Fixed layer height initialization edge case bug that affected the first layer on the baseplate
• Fixed edge case with remelting and rapid cooling/reheating of cells where time step would attempt to fast-forward despite the presence of superheated liquid cells whose solidification had not yet been modeled
• Microstructure analysis moved into separate sub-package

Minimum dependency version updates:

• Kokkos 3.2
• CMake 3.12

New optional dependency:

• nlohmann/json (minimum 3.10)
