# Meilisearch v1.50 release notes

> Released July 20, 2026

## New Features

**Scalable Dynamic Search Rules**

The Dynamic Search Rules API has been revamped to scale to 75,000 rules without impacting search performance. Key changes include:

* New `DELETE /dynamic-search-rules` route to delete all rules at once
* `priority` field renamed to `precedence`
* `conditions` restructured with separate `query` and `time` condition objects
* A DSR Fuel system with configurable limits via environment variables

**Federated document fetching in sharded configurations**

Document retrieval routes now fetch from all shards by default in network configurations. Use the new `useNetwork: false` parameter to limit retrieval to the local instance.

**Facet wildcard support**

The `facets` search parameter now accepts wildcard patterns (for example, `dogs.*`) to match multiple facet fields at once.

## Breaking Changes

* `PATCH` and `DELETE /dynamic-search-rules/{uid}` now return tasks instead of immediate responses
* `DELETE /dynamic-search-rules/{uid}` no longer returns 404 for non-existent rules
* The `POST /dynamic-search-rules` filter parameter uses `query` instead of `attributePatterns`

## Bug Fixes

* Fixed migration failures when upgrading from v1.48 with empty synonyms
* Fixed quadratic memory consumption in filter processing
* Fixed escaped character handling in filter expressions
* Improved fault tolerance for AWS S3 multipart snapshot uploads
