- - If you are using Elasticsearch 6.6 or 6.7, use Elasticsearch-PHP 6.7 branch.
- - If you are using Elasticsearch 6.0 to 6.5, use Elasticsearch-PHP 6.5 branch.
+ - If you are using Elasticsearch 6.x, use Elasticsearch-PHP 6.0 branch.
  - If you are using Elasticsearch 5.x, use Elasticsearch-PHP 5.0 branch.
  - If you are using Elasticsearch 1.x or 2.x, prefer using the Elasticsearch-PHP 2.0 branch.  The 1.0 branch is compatible however.
  - If you are using a version older than 1.0, you must install the `0.4` Elasticsearch-PHP branch. Since ES 0.90.x and below is now EOL, the corresponding `0.4` branch will not receive any more development or bugfixes.  Please upgrade.
