chore: release v0.21.0 #2303

hugrbot · 2025-06-04T10:21:22Z

This release includes a long list of changes:

The HUGR model serialization format is now stable, and should be preferred over the old JSON format.
Type parameters and type arguments are now unified into a single Term type.
Function definitions can no longer be nested inside dataflow regions. Now they must be defined at the top level module.
Function definitions and declarations now have a Visibility field, which define whether they are visible in the public API of the module.
And many more fixes and improvements.
