[0.11.0] - 2026-06-02

Added

GQL Beta Language Expansion

• Composable GQL read pipelines. Added WITH pipelines, scalar aliases, projection-local row operations, and seeded later MATCH / OPTIONAL MATCH execution over the native graph pipeline substrate.
• Richer scalar expressions and functions. Added arithmetic, string predicates, CASE, scalar functions, and shared expression evaluation for GQL reads, mutations, and graph-row-backed execution.
• DISTINCT and aggregation. Added RETURN DISTINCT, WITH DISTINCT, count, sum, avg, min, max, collect, aggregate DISTINCT, grouping, aggregate row operations, and compact-row output support.
• Read-only set and subquery constructs. Added read-only UNION, UNION ALL, EXISTS {} predicates, and CALL {} subqueries with deterministic ordering, cursors, cap enforcement, correlation caching, and explain output.
• Shortest-path GQL syntax. Added constrained shortestPath and allShortestPaths path assignments backed by the native shortest-path algorithms, including path helper return values.
• Keyed MERGE. Added keyed node and relationship MERGE with ON CREATE SET / ON MATCH SET, mutation stats, mutation RETURN DISTINCT, and transaction-backed atomic execution.
• Native graph pipeline connector APIs. Added Rust, Node.js, and Python access to structured graph pipeline execution and explain surfaces, including async connector parity.

Changed

GQL Execution

• GQL lowering now targets a reusable native graph pipeline substrate. Multi-stage reads, aggregation, unions, subqueries, shortest paths, and keyed merge reuse existing graph-row, graph algorithm, and transaction machinery instead of adding parser-owned execution paths.
• Connector GQL coverage now includes the Phase 34 feature set. Node.js TypeScript declarations, Python stubs, async wrappers, compact rows, cap forwarding, nested graph/path value conversion, and explain fields now cover the expanded GQL Beta subset.
• Docs now present GQL Beta as a composable query surface. README, getting-started, API reference, and GQL subset docs now cover pipelines, aggregation, unions, subqueries, shortest paths, and keyed merge while preserving the native API-first positioning.

Fixed

• Pipeline correctness hardening. Fixed edge cases around scalar alias scope, mixed graph/scalar rows, cursor shape validation, selected-field projection preservation, final-page hydration, null semantics, aggregation caps, and deterministic UNION de-duplication.
• Subquery and shortest-path guardrails. Fixed correlated subquery cache behavior, nested invocation budgeting, CALL row cap handling, optional EXISTS semantics, shortest-path endpoint resolution, row-cap enforcement, and truthful explain output.
• MERGE and mutation parity. Fixed keyed MERGE row counting, mutation profiling, late SET evaluation over created or matched aliases, deterministic mutation RETURN DISTINCT, and transaction-local overlay/coalescing behavior.
