6.0.0

6.0.0 (2026-02-13)

• build!: migrate from Poetry to uv and drop Python 3.9 (866c7e6)
• refactor!: replace python-dateutil with datetime.fromisoformat (7f2bf30)

Bug Fixes

• correct version materialization and cross-version query results (5434750)
• handle language-tagged literals and safe triple removal (ed38d74)
• prune stale SPARQL clients from dead executor threads (1de40de)
• remove SPARQL client pooling that caused flaky CI failures (b829dc4)
• replace copy.deepcopy with _copy_dataset to prevent rdflib index corruption (eccafba)

Features

• add BEAR benchmark suite with QLever backend (49975fb)
• add include_all_timestamps option to VersionQuery (4d703a1)
• benchmark: add CLI arguments, resume support, and subprocess isolation for VQ queries (743bac2)
• benchmark: add multi-granularity support and comparison plots (9d55845)
• benchmark: add OSTRICH comparison and ingestion timing (67844cc)
• benchmark: enable OSTRICH multi-snapshot ingestion strategies (0e9942e)
• extract OCDM converter into reusable library module (9c8cee8)
• switch VersionQuery results to SPARQL JSON bindings format (514c93d)

Performance Improvements

• batch SPARQL queries and set-based reconstruction for VM/VQ/DM (8bd7bf1)
• converter: optimize N-Triples parsing and I/O pipeline (df713ba)
• normalize typed literals for O(1) graph removal in update queries (0ff6557)
• reduce overhead from redundant copies, pyparsing, and sequential I/O (4e9ff8f)
• remove dead code and use server-side entity discovery in DeltaQuery (094f942)
• remove redundant DISTINCT from update query entity discovery (c38c5f4)
• replace pyparsing-based SPARQL UPDATE parser with regex (572ba47)
• replace rdflib Dataset with N3 string sets for internal state (3e698ac)
• replace ThreadPoolExecutor with ProcessPoolExecutor on Linux (6271087)
• simplify provenance query and remove DISTINCT from all internal queries (beb91a7)
• stream cross-version VersionQuery to avoid O(N) dataset copies (15c0bb2)
• use set-based pattern matching for single-version VersionQuery (ced44ca)
• use tuple instead of frozenset and skip single-timestamp alignment (6d2117b)

BREAKING CHANGES

• date/time values must now be in ISO 8601 format.
  Non-ISO formats (e.g., "May 21, 2021") are no longer accepted.
• get_state_at_time returns empty entity_snapshots
  dict when include_prov_metadata is False.
• Python 3.9 is no longer supported. Minimum required
  version is now Python 3.10.

5.0.1

5.0.1 (2025-05-29)

Bug Fixes

• agnostic_entity: isolate recursive collection methods (b51686d)

5.0.0

5.0.0 (2025-05-29)

Features

• Add script to find representative entities for benchmarking (c457cee)
• agnostic_entity: remove cache and enhance entity relationships (b9258b7)
• Enhance entity selection script with local file analysis and improved SPARQL querying (bd5d871)

BREAKING CHANGES

• agnostic_entity: - Added new parameters to AgnosticEntity:
  • include_related_objects: Enables inclusion of related objects
  • include_merged_entities: Controls inclusion of merged entities
  • include_reverse_relations: Manages reverse relationship inclusion

• Removed all caching functionality as it was deemed obsolete and non-functional
• Increased test coverage for new features
• Removed untested and deprecated features

This change requires updates to all code that instantiates or interacts with AgnosticEntity objects.
