== 7.0.0-alpha1 Release Notes
The changes listed below have been released for the first time in Elasticsearch 7.0.0-alpha1.
[[breaking-7.0.0-alpha1]]
[float]
=== Breaking changes
Core::
* Tribe node has been removed in favor of Cross-Cluster-Search
Cross-Cluster-Search::
* `http_addresses` has been removed from the <<cluster-remote-info>> API
because it is expensive to fetch and no longer needed by Kibana.
Rest API::
* The Clear Cache API only supports `POST` as HTTP method
Aggregations::
* The Percentiles and PercentileRanks aggregations now return `null` in the REST response,
instead of `NaN`. This makes it consistent with the rest of the aggregations. Note:
this only applies to the REST response, the java objects continue to return `NaN` (also
consistent with other aggregations)
