This release introduces fixes for a regression in v1.45.0, where we were batching deletions by filter with other deletions or additions. It also enables the new settings indexer to support more parameters, making the engine faster to index documents when those settings are specified.
### ✨ 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.
