v22.08.00

Release 22.08.00 features a variety of random distribution implementations (backed by cuRAND), distributed prefix scan operators, and a complete implementation of sorting for multi-node multi-CPU execution. This release also includes several quality-of-life changes and bug fixes, including type annotations for all but one Python module, improvements to the parallel test driver, fixes for several operators when inputs are empty, and proper handling of ndarrays passed as array sizes or indices.

Conda packages for this release are available at https://anaconda.org/legate/cunumeric.
