This bug-fix release principally addresses the Legion backend: ghost copies are faster, ntree topology instances (which are still Legion-specific) initialize correctly, and the common field-resizing warnings are avoided. See the release notes for more information.

This feature release adds a new topology category ntree, a more powerful interface to narray, several other topology utilities (including support for rendezvous operations between meshes), a complete, documented set of public header files, a more flexible system for initialization, and additional range support. It also includes a number of bug fixes, particularly with narray auxiliaries and Legion performance.

See the release notes for more information.

This bug-fix release principally addresses problems with ragged fields, command-line options, and the control model. The code quality in the examples is also improved. See the release notes for more information.

This feature release formally adds the structured and unstructured mesh topologies that existed only in unfinished forms in 2.1.0. The API documentation is also much improved to avoid similar confusion in the future. See the release notes for more information.
