### ✨ Enhancement

- Support exact and disable on numbers in the new settings indexer by @Kerollmops in https://github.com/meilisearch/meilisearch/pull/6398
    Introduce support for exact words and disable-on-words parameters in the new settings indexer, making the engine more efficient when changing these settings.
    
- Support computing prefixes in the new settings indexer by @Kerollmops in https://github.com/meilisearch/meilisearch/pull/6391
    Support for the prefix search settings in the new settings indexer, so that changing this parameter makes the engine more efficient.

### 🪲 Bug fixes

- Better limit read bytes when creating the S3 multipart part by @Kerollmops in https://github.com/meilisearch/meilisearch/pull/6405
    This fixes an issue we had with the multipart part size by ensuring we never construct a part larger than the defined multipart part size. With this fix, we always create a multipart with the provided multipart part size, except for the last part. Thanks, @vidit-virmani, for the help investigating the issue.

- Batch of `documentDeletionByFilter` with `documentAdditionOrUpdate` by @Kerollmops and @ManyTheFish in https://github.com/meilisearch/meilisearch/pull/6415
    Correctly implement the support for auto-batching deletion by filter with document replacement and updates. This fixes a regression introduced in v1.45.0.

- Fix a panic with incomplete filters by @Kerollmops in https://github.com/meilisearch/meilisearch/pull/6421
    Fixes an internal panic when a filter is incomplete by returning an error instead.
