# Meilisearch v1.5 release notes

> Released November 20, 2023

## New Features

### Snapshots on-demand

A new `/snapshots` API route allows you to create snapshots manually whenever needed:

```bash theme={null}
curl -X POST http://localhost:7700/snapshots
```

This route returns a summarized task object. By default, snapshots are created in the `/snapshots` directory, which you can customize using the `--snapshot-dir` configuration option.

### Experimental feature: Export Puffin reports

Meilisearch can now automatically export `.puffin` reports to help diagnose performance issues. Enable this experimental feature using the `/experimental-features` endpoint:

```bash theme={null}
curl \
 -X PATCH 'http://localhost:7700/experimental-features/' \
 -H 'Content-Type: application/json' \
 --data-binary '{"exportPuffinReports": true}'
```

## Improvements

### Indexing speed improvements

Indexing speed has been improved for text-heavy datasets. Datasets with fields containing more than 100 words should see a 5% to 20% reduction in indexing times. Gains are proportional to the amount of words in a document. Note: indexing speed improvements may not be visible in datasets with fewer than 20 words per field.

Please be aware that this optimization might result in minor impact to search result relevancy for queries containing 4 words or more. Contact the Meilisearch team if this significantly affects your application.

### Additional improvements

* The experimental `/metrics` route can now be activated via HTTP in addition to CLI flags
* Added Khmer language support
* The `meilitool` command-line interface is now integrated into the Meilisearch Docker image, providing commands to enforce task cancellation and dump creation for stuck instances. Use `meilitool --help` in the running container for usage information

## Other

### Breaking changes and fixes

* Vector size validation: The API now throws an error when a vector in a search query does not match the size of already indexed vectors
* Fixed search operations on the processing index from hanging
* Fixed search on exact attributes using `attributeToSearchOn`
