- - If you are using Elasticsearch 2.0+, prefer using the Elasticsearch-PHP 2.0 branch.  The 1.0 branch is compatible however.
- - If you are using Elasticsearch 1.0+, you must install the `1.0` or `2.0` Elasticsearch-PHP branch.
+ - If you are using Elasticsearch 5.0+ (master, alpha, beta), use Elasticsearch-PHP dev-master.  A 5.x branch will be cut when Elasticsearch 5.0 GA is released
+ - 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.
  - You should never use Elasticsearch-PHP Master branch, as it tracks Elasticearch master and may contain incomplete features or breaks in backwards compat.  Only use ES-PHP master if you are developing against ES master for some reason.
