3.0.0 - 2026-04-02

Changed

• BREAKING: Require supported Python version >= 3.10.
• Update aiohttp document loader to work with Python 3.14.
  • Minimize async related changes to library code in this release.
  • In sync environment use asyncio.run.
  • In async environment use background thread.
• The default test manifests or directories now default to the ./specifications directory.
• Add ability to run test suites using pytest and make pytest the default way for running (unit)tests.
• The functionality to resolve relative IRIs to absolute IRIs has been moved from context_resolver.py to iri_resolver.py so it can be maintained and tested separately.
  • Migrate the prepend_base(base, iri) function to the resolve(iri, base) function.
  • Move the existing function remove_dot_segments(path) and update the implementation.
  • Migrate the remove_base(base, iri) function to the unresolve(iri, base) function and update the implementation to use stdlib urllib.parse and urllib.unparse to replace the custom implementation.
  • Update code to use resolve(iri, base) and unresolve(iri, base) instead. Invalid base IRIs (including None) are no longer allowed, hence missing base IRIs in the JSON-LD context are now handled outside the function call.
  • Add unittests
• BREAKING: the custom cause and traceback attributes on JsonLdError are replaced by Python exception chaining and the built-in __cause__ attribute.
• BREAKING: The IdentifierIssuer class was moved to identifier_issuer.py. It's now available at pyld.identifier_issuer.
• BREAKING: The classes URDNA2015 and URGNA2012 were moved to canon.py. They are now available at pyld.canon.
• jsonld.expand() now accepts a on_property_dropped parameter which is a handler called on every ignored JSON property.
• BREAKING: In cases where there is no document base (for instance, when using a string as input), 'http://example.org/base/' is used as the base IRI when @base is absent or explicitely set to null.
• BREAKING: Some internal parameters were renamed from camelCase to pythonic:
  • requestProfile to request_profile in load_document()
  • rdfDirection to rdf_direction in _list_to_rdf() and _object_to_rdf()
