HeliosDB Full v8.0.0 Release Notes

Theme: Major version bump — stabilization + v7.x feature roll-up

Highlights

v8.0.0 marks the major version bump. No breaking changes for SQL / wire protocols — the bump reflects the productization of the v7.1–v7.4 feature wave under a stable release header.

v8.0.x is a roll-up release. See the v7.x release notes in this directory for theme-by-theme context.

What’s New

Stabilization

Previously separate features now included in the build — geospatial, quantum, ML / AI features, query advisor, auto-index advisor, RL-based cache, MAB load balancer, PITR, triggers.

v7.x Feature Roll-up Under Stable Header

The full v7.1–v7.4 feature wave ships under v8.0.0 release governance:

v7.1.0 — Quantum optimizer Tier-1 safe integration (RELEASE_NOTES_v7.1.0).
v7.2.0 — Feature exposure: 100+ SHOW commands, 16 REST admin endpoints, EXPLAIN 7 formats, 96+ Redis commands (RELEASE_NOTES_v7.2.0).
v7.3.0 / v7.3.1 / v7.3.23 — WordPress / MySQL compatibility, AI-native Redis (134+), MongoDB AI commands, S3-compatible HTTP gateway, DDL + data persistence hardening (RELEASE_NOTES_v7.3.0).
v7.4.0 — RAG-native SQL surfaces (graph_traverse, hybrid_search), PREPARE COMPILED, MCP server (RELEASE_NOTES_v7.4.0).

Migration

Drop-in upgrade from v7.4.x. No SQL or wire-protocol breaking changes. Operators can:

Upgrade in place — wire-compatible with all v7.x clients.
Continue using --config files unchanged.
Optionally enable previously separate features via flags (e.g. --features research for quantum, GPU, genomics).

See v7.4.0 release notes for the detailed migration path from v7.3.x to the v7.4 / v8.0 baseline.
