Version 3.2.12

• Make sure argument to URI.intern is a string.
• In URI#freeze, synchronize mutex before checking for frozen? This was a race condition.

Release 3.3.2

• Fix problem parsing ill-formed URI query parameters such as "?&a".
• Don't normalize literal direction so that validation can work.
• Add check to see if subject implements supports? before using it, which isn't the case for a Writer.
• Fix documentation on RDF::Query#initialize and #execute to note that variable graph names do not match the default graph due to SPARQL semantics.
• Remove CHANGES.md
• Reference GitHub Release Notes from README.
• CI on Ruby 3.3.
• Add expllicit dependencies on base64 and bigdecimal gems.
• Fix some IRI regular expressions.
• Add support for RDF 1.2 Triple Terms and deprecation notices for RDF-star quoted triples. (provisional)
• Even though deprecated, when matching a quoted triple (<< ... >>) be sure it's not a triple term (<<( ... )>>).
• Add rdf:reifies to the RDF vocabulary.
• Implement Literal#english? to aid matching English literals. (@artob)
• Update #start_with? to match String#start_with signature. (@tpendragon)

Release 3.3.1

When Mutable#load is called with a base_uri option, it takes precedence over the resource location.

Release 3.3.0

• Add support for directional language-tagged strings from RDF 1.2.
• Consolidate N-Triples and N-Triples Star grammars. Use LANG_DIR terminal instead of LANGTAG.
• Removes support for legacy text/plain (as an alias for application/n-triples) and text/x-nquads (as an alias for application/n-quads)
• Cleanup RDF* nomenclature, and use :quoted_triples instead of :rdfstar for supports?.
• Add :base_direction as something supported (or not) by writeable.
• Require rdfstar option to read directional language-tagged strings.
• Add missing Statement#dup. Does not duplicate blank node components.
• Added documentation to clarify that term canonicalization is not the same as Graph/Dataset canonicalization, which is impleented in the rdf-normalize gem.
• Add Enumerable#canonicalize method, which can be overridden by rdf-normalize, which normalizes each statement in an enumerable.
• Minimum Ruby version now 3.0.

Release 3.2.11

• Ruby extensions no longer necessary.
• Make Ruby warnings visible and reduce warnings.
• Updates to URI normalization. Fixes #439.

Release 3.2.10

• Fix arguments to Logger.log_depth to pass depth keyword parameter to #log_depth.
• Minor update in mutable to change the way keyword argument overrides work.
• Update N-Triples/Quads ASCII escapes when writing literals based on proposed RDF 1.2 behavior.
• Fix memory leak on RDF::Util::Cache (#438 – @abrisse)

Release 3.2.9

• Narrow list of valid dates/times/dateTimes based on more strict lexical representations from https://www.w3.org/TR/xmlschema11-2/#rf-lexicalMappings-datetime
• Update CLI filtered option to allow Array or Proc in addition to a single value. This allows, for example, a command to be associated with multiple formats.

Release 3.2.8

• Query#execute and Pattern#execute can take a Solution for bindings, in addition to a hash. This supports passing pre-bound variables from SPARQL.
• When generating docs, add etc/doap files to yard output.
• Fix Dataset#inspect

Release 3.2.7

• Add :uri option to Format,content_type, and uris and to_uri class methods. This allows retrieving the defined format URI for specified formats. (See https://www.w3.org/ns/formats/).
• pass format keyword parameter as option when filtering CLI commands.
• Check for windows drive letter to not confuse it with a URI scheme (windows platform only).

Release 3.2.6

• In Temporal#to_s, set @string if it is nil.
• Reset the string representation for Time values having an hour > 23.
• Temporal#adjust_to_timezone! can certainly take a Literal::DayTimeOffset, in addition to a String.
  Treat the empty string as nil, to remove the timezone.
• Add Solutions#variable_names= to override automated variable name count.
• Add Solutions#== and Solutions#eql?` to test solutions including variable names.
