0.1.6 Release Notes

Release date: 2026-05-16

Summary

This release expands qql-go's retrieval and indexing surface with native dense MMR, richer payload index configuration, payload-aware HNSW tuning, and smaller query-surface fixes that bring the CLI closer to practical day-to-day Qdrant usage.

Highlights

• Dense MMR support adds WITH { mmr_diversity, mmr_candidates } for semantic diversity in dense search results.
• Advanced payload indexing adds richer CREATE INDEX support for keyword, uuid, and text fields, including tenant-aware indexing and text tokenizer controls.
• Payload-aware HNSW tuning adds CREATE COLLECTION ... HNSW { payload_m: <n> }.
• Search param parity and cursor fixes add indexed_only, quantization search params, boolean filter literals, and native numeric SCROLL offsets.
• Docs and demos refresh updates the bundled skill references and runnable examples to showcase the new features end to end.

Supported syntax added in this release

New Syntax in 0.1.6

CREATE COLLECTION docs HYBRID HNSW { payload_m: 16 }
CREATE INDEX ON COLLECTION docs FOR tenant_id TYPE keyword WITH { is_tenant: true, on_disk: true }
CREATE INDEX ON COLLECTION docs FOR external_id TYPE uuid WITH { on_disk: true, enable_hnsw: false }
CREATE INDEX ON COLLECTION docs FOR title TYPE text WITH { tokenizer: 'word', min_token_len: 2, max_token_len: 20, lowercase: true, phrase_matching: true }
SEARCH docs SIMILAR TO 'vector database tuning' LIMIT 10 WITH { indexed_only: true }
SEARCH docs SIMILAR TO 'vector database tuning' LIMIT 10 WITH { quantization: { ignore: true, rescore: false, oversampling: 2 } }
SEARCH docs SIMILAR TO 'vector database tuning' LIMIT 10 WITH { mmr_diversity: 0.5, mmr_candidates: 25 }

Packaging

Release bundles include:

• qql-go (Linux amd64, Linux arm64, Windows amd64, macOS arm64)

Tagged releases also publish:

• qql-go_0.1.6_checksums.txt

Known limits

Known Limits

• MMR currently supports dense SEARCH and dense grouped SEARCH only. USING HYBRID, USING SPARSE, and RECOMMEND reject MMR settings.
• RERANK is cloud-only. Local and external modes reject rerank queries.
• CREATE COLLECTION still does not expose custom vector sizes or distance metrics through QQL syntax.

Validation

Release prep was validated with:

• go run docs/dev_tasks.go prepare-release --version 0.1.6
• go run docs/dev_tasks.go release-validate --version 0.1.6
• live local smoke runs against the runnable demo scripts and a dedicated local-mode script covering payload_m, tenant-aware indexing, text indexing, and dense MMR
