+## [0.30.0] - 2025-01-24
+
+### Fixed
+- Finalize the decoupling of `base_uri` from graph `identifier`.
+  - Blame the conflated naming of `publicID` in RDFLib for that confusion. 
+- `load_from_source` will now correctly detect and use the BaseURI of files passed in, for relative URIs.
+  - Fixes #281
+
+### Changed
+- Update to Poetry v2.0 and new pyproject.toml format.
+- Removed "Black", switched to "Ruff" for formatting as well as linting.
+- Switched to parsing `file:` IRIs in line with the RDF spec, and allow (base-less, or root-less) relative `file:` IRIs (as per the RDF spec).
+  - But "<file:>" IRIs in Turtle files are now _not_ made relative to BaseURI, because they are relative to the CWD.
