What's New
CodeChunker rewrite delivers ~44% faster indexing and 14-18% lower query latency with slightly better search quality.
New Features
- Rewritten CodeChunker with substantially faster indexing and lower query latency.
- Search quality improved slightly, with NDCG@10 rising from 0.854 to 0.856.
Improvements
- Index time cut by roughly 44.5% (about 5.1s down to 2.9s) in the published benchmarks.
- p50, p90, p95 and p99 latencies reduced by 14-18% across the board.
- Dependency bumps for urllib3, langchain-core, mako and authlib.
- turbopuffer requirement widened to >=1,<3, allowing a broader range of versions.
Upgrade Notes
No migration steps are described; the change is a drop-in performance update to the chunking path. Verify that your pinned turbopuffer version still satisfies the widened >=1,<3 constraint and re-run any search-quality baselines, since chunk boundaries may shift. Note the versioning scheme jumps from a date-style tag (26.5.12) to semver (v1.6.6), so pin explicitly rather than relying on ordering.
