## Upgrading

No need to run "update.php" or any other migration scripts.

**Get the new version via Composer:**

* Step 1: if you are upgrading from SMW older than 4.0.0, ensure the SMW version in `composer.json` is `^4.1.3`
* Step 2: run composer in your MediaWiki directory: `composer update --no-dev --optimize-autoloader`

**Get the new version via Git:**

This is only for those that have installed SMW via Git.

* Step 1: do a `git pull` in the SemanticMediaWiki directory
* Step 2: run `composer update --no-dev --optimize-autoloader` in the MediaWiki directory

**Upgrading Elasticsearch:**
This version of SMW uses Elasticsearch 7.10.2 (if you have enabled it). If you are using Elasticsearch as a backend, then you need to perform the following changes:
* Step 1: Upgrade your version of Elasticsearch to 7.10.2 (if you are using docker that should work without any other action than changing the version number)
* Step 2: Make sure your version of the elasticsearch package is right, you might want to add it to the composer.local.json: `COMPOSER=composer.local.json composer require elasticsearch/elasticsearch "7.17.2"`
* Step 3: Add $smwgElasticsearchCredentials after $smwgElasticsearchEndpoints:

```
$smwgElasticsearchEndpoints = [ 
    [
        'host' => $elasticSearchHost,
        'port' => 9200,
        'scheme' => 'http'
    ]
];

$smwgElasticsearchCredentials = [
    'user' => $elastic_user,
    'pass' => $elastic_password,
];
```
