Version 19.06.0 (June 27, 2019)

• Legion
  • All tools (Legion Prof, Legion Spy, etc.) now support Python 2 and 3
  • The flag -lg:warn_backtrace prints a backtrace on each warning
    to allow easier pinpointing of problematic code
• Realm
  • Support for building against debug versions of GASNet
  • Significantly reduced runtime overhead for small Realm tasks
  • External HDF5 instances work with datasets in groups
  • Scheduler locking allows spin-waiting for non-reentrant
    operations (e.g. Python module imports)
  • Memory size (e.g. "-ll:csize") arguments accept k/m/g/t
    size suffixes
  • Better error messages when Realm memory sizes are too large
• Regent
  • The image, preimage and restrict partitioning operators now
    accept an optional disjoint or aliased keyword to specify the
    disjointness of the resulting partition
  • The address of operator (&) is now supported
  • Support for explicit field maps for HDF5
• Legion Prof
  • Menu option to select a subset of the profile information
    for viewing
  • Grouping of memory channels, utilization and additional details
    such as source and destination nodes/processors associated with
    the channels
  • Physical instances contain additional information about the regions
    they belong to
• Python
  • Support for partitioning operators equal and restriction
  • Support for bool and complex types
  • Support for must epoch launches
  • Support for returning a future out of a fence
  • Fixes for macOS
