## Executive Summary (TL;DR)
Meilisearch v1.33.1. Source highlight: In Meilisearch v1.33.1, we released a security fix that affected the dump import, improvements to vector store relevance in massive databases, and a fix related to ranking scores.

## Improvements
- We updated the vector store to trigger linear scanning even on bigger databases, leading to improved performance and so better result quality when the search cutoff is reached. This applies in particular when the number of filtered candidates is small relative to the number of documents in the index

## Bug Fixes
- Cloud users: you don't need to do anything. We found no evidence of exploitation of this vulnerability on Meilisearch Cloud.
- Open-source users: if you allow importing dumps from an untrusted source, we recommend you update to v1.33.1
- We fixed a bug where only the first non-blocking buckets were taken for the non-final ranking rules. This improves the quality of search results when the search cutoff triggers, especially when vector search and a sort are involved
