[1.0.16] - 2026-03-12

Changed

  • Cypher openCypher strictness hardening:
    • Tightened SET += inline map parsing to reject malformed map literals.
    • Tightened CREATE ... RETURN and related parser/validation paths to reject permissive invalid forms.
    • Ensured UNWIND ... SET n = row map-literal handling follows expected Cypher semantics.
  • Cypher execution correctness:
    • Fixed SET ... WITH ... RETURN row semantics so property updates remain visible in trailing pipeline clauses.
    • Added protection against non-progressing CALL ... IN TRANSACTIONS iterative loops.
    • Added strict malformed relationship-pattern rejection in traversal/match paths.
  • Cypher schema/index compatibility:
    • Restored Neo4j-compatible CREATE INDEX parsing for parenthesized node patterns.
    • Added compatibility support for additional CREATE INDEX / CREATE FULLTEXT INDEX syntax variants and persistence paths.
    • Added qualified SHOW ... INDEXES routing/handling (FULLTEXT, RANGE, VECTOR) with deterministic type filtering.
  • Web UI routing behavior: Updated UI router behavior to preserve/enforce trailing slash paths for proxy compatibility.
  • Heimdall model source update: Updated Docker model-download source for Qwen GGUF in Heimdall images.

Fixed

  • Index parsing bug: Fixed CREATE INDEX FOR (n:Label) ON (n.prop) label parsing edge case where ) could be captured as part of label token.
  • Silent schema no-op bug: Fixed successful-but-non-persisted index creation paths for compatibility syntaxes.
  • SHOW INDEX compatibility gap: Fixed SHOW FULLTEXT INDEXES command handling and added qualified SHOW RANGE/VECTOR INDEXES support instead of unsupported-command errors.
  • Pre-commit conflict handling: Hardened .githooks/pre-commit workflow behavior to avoid merge-conflict-inducing side effects.

Tests

  • Expanded Cypher deterministic branch coverage across parser, schema/index, dispatch, transaction, mutation, traversal, APOC/call wrappers, and compatibility paths.
  • Added targeted regression tests for schema routing with async storage stacks and Neo4j-compatible index command variants.
