The detailed list of feature additions and contributed enhancements + fixes that are part of the release are provided below.
Features

  *   PR #424, #445, #461, #462, #467, #474: Significant feature additions in mbtempest to improve the TempestRemap-based mapping weights generation workflow
– Expose both Kd-tree and advancing front intersection
– Verifications of mapping weight generation for very high-res cases at scale
– Improve mbconvert to transform TR supported file formats to MOAB h5m and vice-versa
– Ability to write out the computed remapping weights in parallel to a h5m file is now supported. A h5mtoscrip utility tool to convert the h5m file to SCRIP format is available.
– Add an extra verification option for maps computed with mbtempest to validate projection weights
– Improve master-slave partitioner tool
– Performance enhancements: Several optimizations in the iMOAB implementation and OnlineMap computation routines have been implemented
  *   PR #437: Allow ability to support empty parts in parallel mesh handling
  *   PR #454, #464, #475: Enable coupling and consistent remap of data between discrete meshes and point cloud representations
– A new ParCommGraph class is now available to store communication patterns between MPI groups
– Feature additions support rendezvous coupling that has been tested for multi-way transfer between atmosphere, ocean, land components
  *   PR #465: Add a new KDtree-based intersection to replace advancing front intersection when dealing with source grids with holes
  *   PR #471: Introduce the concept of an “inferred” master-slave partitioning method using Zoltan RCB algorithm in mbpart
– This feature provided a significant speedup for offline remapping calculations on a sphere
– TODO: Test similar ideas for other coupled computational problems
  *   PR #482: Domain file reader in NetCDF format to support E3SM integration
  *   PR #485: Extensive CMake configuration updates to support Windows platform builds
  *   PR #486: Adding a new option for area computations using Gauss quadrature based integration instead of spherical excess
Enhancements

  *   PR #419: Cache the latest facet for RayHistory in OBB tree
  *   PR #420, #435: Global ID default value (unset) is now -1, while DOFs related to Global ID start from 1
  *   PR #429: Option for consistent (multiple) ghost layers in thin partitions
  *   PR #438: Improve coexistence of LAPACK and Eigen3 in configurations

  *   PR #444, #449: CMake build improvements related to MPI, HDF5, OSX
  *   PR #446: Option to reset Global IDs during partitioning
  *   PR #455: Enforce MOAB flags to add c++0x flags if supported
  *   PR #463: Update default download option for NetCDF(4.6.3), HDF5 (1.10.1)
  *   PR #468: PyMOAB bindings to set_connectivity
  *   PR #475: Improve regridding intersection robustness
  *   PR #483: Add a new download option to sync large files from FTP site to avoid bloating repository with static meshes
  *   PR #488: Enforce uniform formatting of the entire source repository with clang-format tool with updated coding guidelines
Fixes
