0.9.3 Release Highlights

(adapted from Conduit's Changelog )

Released 2025-01-27

Added conduit::blueprint::mesh::examples:generate driver functions that supports creating any blueprint example mesh with options.
Added conduit::blueprint::mesh::examples:generate_default_options functions that provide default options values for conduit::blueprint::mesh::examples:generate.
Added python API support for conduit::blueprint::mesh::examples:generate and conduit::blueprint::mesh::examples:generate_default_options.
Added gyre example mesh, which provides a simple velocity vector field.
Added bent_multi_grid example mesh, which provides a multi-grid that can contain enhanced and reduced connectivity. bent_multi_grid can produce meshes like the example at http://visitusers.org/index.php?title=Representing_ghost_data#Enhanced_and_Reduced_Connectivity_Zones .
Added new utilities for material sets: conduit::blueprint::mesh::matset::count_zones_from_matset(), conduit::blueprint::mesh::matset::is_material_in_zone(), and conduit::blueprint::mesh::matset::create_reverse_material_map().
Added a new example, conduit::blueprint::mesh::examples::venn_specsets(), which covers the breadth of species set representations.

Added limited support for species sets for Silo/Overlink I/O. Multi-buffer element-dominant species sets can be written to Silo and the same can be read from Silo. Additional species set flavors will come online in a later release.
Added support for conduit_yaml and conduit_base64_yaml I/O cases.
Standardized the way that Relay Silo Save handles name collisions and non-idiomatic Silo names.

Changed the MPI CMake target used by conduit from MPI:MPI_CXX to MPI:MPI_C to provide better compatibility with downstream tools.
Added vendored yyjson v0.10.0 as new and default JSON parser. yyjson has an MIT license that is compatible with Debian's Free Software Guidelines, where RapidJSON is not (https://wiki.debian.org/qa.debian.org/jsonevil). You can still use RapidJSON by setting the new CMake option ENABLE_YYJSON to FALSE.
The DataType::equals() method now correctly takes striding into account.

Certain algorithms that use MPI tags had their tag values lowered since some MPI implementations do not support large values.
Changed the name of conduit::blueprint::mesh::matset::to_sparse_by_element() to conduit::blueprint::mesh::matset::to_uni_buffer_by_element() to be more consistent with similar function names.
Expanded the ways species sets can be represented in Blueprint to include sparse by element and sparse by material representations, much like material sets.
Updated conduit.relay.io.blueprint.{load_mesh|read_mesh} to support reading and writing Silo files when Conduit is built with Silo support.
Updated conduit.relay.io.blueprint.{load_mesh|read_mesh} to use improved logic to auto detect the format (hdf5 , silo, yaml, or json) of mesh blueprint root files. Added silo logic, and fixed prior logic that could confuse yaml as json files due to format specifiers in partition pattern strings.

User-supplied warning and error handlers are suspended during conduit::relay::communicate_using_schema::execute() so exceptions will be thrown properly when there is an MPI error. The handlers are restored before the execute method returns.
conduit::relay::communicate_using_schema::execute() flushes logs as they are generated, in case of error. This is mostly to facilitate internal debugging.
Changes were made to how Relay queries the upper limit for MPI tags to work around problems on some systems.
Rewrote conduit::blueprint::mesh::specset::to_silo() to allow it to support specsets that do not use all the materials in the associated matset.
