 ### Changed
 
 #### General
+- Conduit now requires C++14 and CMake 3.21 or newer.
 - Improved the efficiency of json parsing logic.
 - The `conduit_relay_io_convert` program was enhanced so it can read/write Blueprint root files by passing _"blueprint"_ for the read or write protocols.
 - The `conduit_adjset_validate` program now writes a point mesh for each adjset groups if the _-output_ argument is supplied.
+- Updated to BLT 0.6.0
 
 #### Blueprint
 - The `conduit::blueprint::mpi::mesh::partition_map_back()` function was enhanced so it accepts a "field_prefix" value in its options. The prefix is used when looking for the `global_vertex_ids` field, which could have been created with a prefix by the same option in the `conduit::blueprint::mpi::mesh::generate_partition_field()` function.
