# Meilisearch v1.52 release notes

> Released August 3, 2026

## New Features

**SSE streaming routes for tasks and batches (experimental)**

Two new Server-Sent Events (SSE) routes allow you to subscribe to live updates instead of polling:

* `GET /tasks/stream`: streams task status updates in real time
* `GET /batches/stream`: streams batch status updates in real time

These routes are experimental. Enable them with the `tasksStreamingRoute` experimental feature flag before use.

## Improvements

**Faster document retrieval**

Document formatting has been optimized from O(n) to O(1) complexity, delivering significant speed improvements when retrieving large numbers of documents (more than 20 items).

## Bug Fixes

* Fixed duplicate pins appearing in federated search results
* Fixed unnecessary settings updates when configuration remains unchanged
