v22.03.00

Release 22.03 adds communicator support for tasks, allowing intra-task communication to be performed in a safe way. The new task type for constructing task trees is useful for operations implementing set semantics, such as distributed value de-duplication. The build system is also extended such that CUDA tasks can use offline device linking. Finally, the auto-partitioner is revised and extended to handle distributed gather/scatter copies correctly.

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