• SPARQL: Fixed handing of HAVING clause with variable composition. Closed
  issue #936 and issue
  #935, PR
  #1093.
• JSON-LD parser: better support for content negotiation. Closed issue
  #1423, PR
  #1436.
• Removed the following functions that were marked as deprecated and scheduled
  for removal in version 6.0.0: Graph.load, Graph.seq, Graph.comment,
  Graph.label. PR #1527.
• Use functools.total_ordering to implement most comparison operations for
  rdflib.paths.Path. Closed issue
  #685, PR
  #1528.
• Fixed error handling for invalid URIs. Closed issue
  #821, PR
  #1529.
• InfixOWL: Fixed handling of cardinality 0. Closed issue
  #1453 and issue
  #944, PR
  #1530.
• Added quad support to handling to rdflib.graph.ReadOnlyGraphAggregate.quads.
  Closed issue #430, PR
  #1590
• Fixed base validation used when joining URIs. PR
  #1607.
• Add GEO defined namespace for GeoSPARQL. Closed issue
  #1371, PR
  #1622.
• Explicitly raise exception when
  rdflib.plugins.stores.sparqlstore.SPARQLStore.update is called. Closed
  issue #1032, PR
  #1623.
• Added rdflib.plugins.sparql.processor.prepareUpdate. Closed issue
  #272 and discussion
  #1581, PR
  #1624.
• Added rdflib.namespace.DefinedNamespaceMeta.__dir__. Closed issue
  #1593, PR
  #1626.
• Removed TypeCheckError, SubjectTypeError, PredicateTypeError,
  ObjectTypeError and ContextTypeError as these exceptions are not raised by
  RDFLib and their existence will only confuse users which may expect them to be
  used. Also remove corresponding check_context, check_subject,
  check_predicate, check_object, check_statement, check_pattern that is
  unused. PR #1640.
• Improved the population of the Accept HTTP header so that it is correctly
  populated for all formats. PR
  #1643.
• Fixed some issues with SPARQL Algebra handling/translation. PR
  #1645.
• Add nquads to recognized file extensions.
  PR #1653.
• Fixed issues that prevented HexTuples roundtripping.
  PR #1656.
• Make rdflib.plugins.sparql.operators.unregister_custom_function idempotent.
  Closed issue #1492,
  PR #1659.
• Fixed the handling of escape sequences in the N-Triples and N-Quads parsers.
  These parsers will now correctly handle strings like "\\r". The time it
  takes for these parsers to parse strings with escape sequences will be
  increased, and the increase will be correlated with the amount of escape
  sequences that occur in a string. For strings with many escape sequences the
  parsing speed seems to be almost 4 times slower. Closed issue
  #1655, PR
  #1663.
  • Also marked rdflib.compat.decodeStringEscape as deprecated as this
    function is not used anywhere in RDFLib anymore and the utility that it does
    provide is not implemented correctly. It will be removed in RDFLib 7.0.0
• Added an abstract class IdentifiedNode as a superclass of BNode and
  URIRef. Closed issue #1526,
  PR #1680.
• Fixed turtle serialization of rdf:type in subject, object. Closed issue
  #1649, PR
  #1649.
• Fixed turtle serialization of PNames that contain brackets. Closed issue
  #1661, PR
  #1678.
• Added support for selecting which namespace prefixes to bind. Closed issue
  #1679 and issue #1880, PR
  #1686, PR
  #1845 and PR
  #2018.
  • Also added ConjunctiveGraph.get_graph.
  • Also added an override argument to Store.bind which behaves similarly to
    the override parameter for NamespaceManager.bind.
  • Also fixed handing of support of the override parameter to
    NamespaceManager.bind by passing.
• Eliminated a DeprecationWarning related to plugin loading issue
  #1631, PR
  #1694.
• Removed the rdflib.graph.ContextNode and rdflib.graph.DatasetQuad type
  aliases. These were not being widely used in RDFLib and were also not correct.
  PR #1695.
• Added DefinedNamespace.as_jsonld_context. PR
  #1706.
• Added rdflib.namespace.WGS for WGS84. Closed issue
  #1709, PR
  #1710.
• Improved performance of DefinedNamespace by caching attribute values. PR

  #1773 and PR
  #2003.

  #1779.

  raising an exception during evaluation before but is now correctly handled.

  #1794.
• Propagate exceptions from SPARQL TSV result parser. Closed issue
  #1477, PR
  #1809

  with querying. Closed issue
  #1808, PR
  #1821
• Fixed handing of DefinedNamespace control attributes so that
  inspect.signature works correctly on defined namespaces. PR
  #1825.
• Fixed namespace rebinding in Memory, SimpleMemory and BerkelyDB stores.
  Closed issue #1826, PR
  #1843.
• Fixed issues with the N3 serializer. Closed issue
  #1701 and issue
  #1807, PR
  #1858:
  • The N3 serializer was incorrectly considers a subject as seralized if it is serialized in a quoted graph.
  • The N3 serializer does not consider that the predicate of a triple can also
    be a graph.

  #1868, PR
  #1869.

  to https://rdflib.github.io. Closed issue
  #1824, PR
  #1901.
• Fixes handling of non-ascii characters in IRIs. Closed issue
  #1429, PR
  #1902.
• Pass generate to NamespaceManager.compute_qname from
  NamespaceManager.compute_qname_strict so it raises an error in the same
  case as the "non-strict" version. PR
  #1934.
• Log warnings when encountering ill-typed literals.
  PR #1944.
• Fixed error handling in TriX serializer. PR
  #1945.
• Fixed QName generation in XML serializer.
  PR #1951
• Remove unnecessary hex expansion for PN_LOCAL in SPARQL parser. Closed issue
  #1957,
  PR #1959.
• Changed the TriX parser to support both trix and TriX as root element. PR
  #1966.
• Fix SPARQL CSV result serialization of blank nodes.
  PR #1979.
• Added a URIRef.fragment property.
  PR #1991.
• Remove superfluous newline from N-Triples output. Closed issue
  #1998, PR
  #1999.

[aucampia]

@ashleysommer @nicholascar @white-gecko one of you will have to upload to pypi or add me (iwan.aucamp) to the project as you are the only maintainers on https://pypi.org/project/rdflib/

approximate steps [ref]:

git clone git@github.com:RDFLib/rdflib.git
git fetch --all
git checkout 6.2.0

python3 -m pip install --upgrade build twine keyring
python3 -m build
python3 -m twine check dist/*
python3 -m twine upload --repository testpypi dist/* # this will only work for @ashleysommer as he is the only maintainer for rdflib on testpypi
python3 -m twine upload dist/*

[aucampia]

Once uploaded I will announce on twitter and mailing list.
