v22.05.00

Release 22.05 features complete support for advanced indexing and related indexing routines (compress and take), a multi-node multi-GPU sorting implementation for multi-dimensional ndarrays, window functions, several matrix/tensor operations (trace, matrix_power, multi_dot, and einsum_path) and primitive support for FFT on a single GPU using cuFFT.

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