v1.0.29 - UNION Station

[v1.0.29] - 2026-03-23

Added

• Optimistic metadata for async CREATE operations, so clients can receive immediate creation context while writes complete.

Fixed

• Improved Cypher compatibility and correctness across complex mutation and grouped-query patterns.
• Restored correctness and reduced overhead for correlated CALL/UNION subquery execution.
• Improved correlated write-subquery behavior for WITH ... CREATE/MERGE/... flows.
• Aligned Bolt behavior with HTTP/GraphQL for text-based vector query usage.
• Improved async transaction response consistency.
• Fixed DELETE/DETACH DELETE deduplication and mutation stats accuracy under repeated OPTIONAL MATCH expansion.
• Improved index planning for key-list lookup patterns to avoid unnecessary scans on read/cleanup workloads.

Tests

• Expanded regression and benchmark coverage for correlated subqueries, vector query paths, mutation shapes, delete deduplication, and key-list/indexed lookup behavior.
• Added exact-shape regressions for production query forms to prevent recurrence of compatibility issues.

Technical Summary

• Focused on Cypher correctness, cross-protocol consistency, and hot-path query performance.
• Release scope covers changes from v1.0.28 to HEAD.
