Version 20.06.0 (June 29, 2020)

• Regent
  • Support for std/format module for type-safe formatted printing
  • Support for documentation with LDoc
  • Support for __future operator to import a C API future
• Legion
  • Support for inlining tasks into leaf contexts
  • Support for global registration callbacks inside of tasks
  • Added semantic tags for source file and line location
  • Support for multi-region accessors for region requirements with
    co-location constraints
  • Changes to semantics of deletion for index spaces, field spaces, and
    logical regions. For details, see: #812
  • Support for creating fields spaces with initial fields
• Realm
  • Subgraphs can be used to capture a template of Realm operations
    that will be executed repeatedly. Subgraph definitions include
    support for "interpolating" values into individual operations'
    arguments on each instantiation of the subgraph template
  • create_weighted_subspaces supports size_t weights for precise
    control over the size of each subspace
  • Added support for omp critical constructs and dynamic loop
    schedules in OpenMP tasks
  • Added support for cudaStreamLegacy and cudaStreamPerThread in
    CUDA tasks
  • Realm logs now include a timestamp (relative to runtime init)
    by default. This behavior can be disabled with -logtime 0
  • Performance improvements for copies/fills of 3D instances spaces in
    GPU device memory
  • Added ability to compute a set of "covering rectangles" for sparse
    index spaces, allowing more compact representation in memory
  • Added MultiAffineAccessor for accessing compact instances
  • Added ability to delete a ProcessorGroup
