## @qdrant/js-client-rest 1

### Breaking changes

- External tools calling the internal port must send the api-key header when internal authentication is enforced. (1.0.0) — [upgrade guide](https://qdrant.tech/documentation/upgrades)

### Behavior and default changes

- The internal API accepts only read-write keys and rejects read-only keys and JWTs. (1.18.0) — [docs](https://qdrant.tech/blog/qdrant-1.20.x)

### Fixes and other changes

- The guidance suggests an oversampling factor of 3 as a starting point; higher oversampling continued to improve accuracy for the tested 3072-dimensional model. (1.15.0) — [docs](https://qdrant.tech/documentation/manage-data/quantization)
- The sweep found rescoring improved accuracy in every tested configuration; the guidance recommends rescoring on, while noting it reads original vectors and can cost disk I/O. (1.15.0) — [docs](https://qdrant.tech/documentation/manage-data/quantization)
