    #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    .

    #1706    .
