=== Breaking changes in 5.0 ===
Migration Plugin
- The elasticsearch-migration plugin (compatible with Elasticsearch 2.3.0
and above) will help you to find issues that need to be addressed when
upgrading to Elasticsearch 5.0.
Indices created before 5.0
- Elasticsearch 5.0 can read indices created in version 2.0 or above. An
Elasticsearch 5.0 node will not start in the presence of indices created
in a version of Elasticsearch before 2.0.
- Indices created in Elasticsearch 1.x or before will need to be reindexed
with Elasticsearch 2.x in order to be readable by Elasticsearch 5.x. It is
not sufficient to use the upgrade API.

multiple replicas failed at once
- Aggregations: A nested nested aggregation falls outside of its parent
nested aggregation bounds
- Field data: Percolator doesn't reduce CircuitBreaker stats in every case
- Field data: Fixed eager fielddata loading
- Bulk API: Ensure that specific failures do not affect whole request
- Search API: Prevent ArrayIndexOutOfBoundsSelection on counter which selects

- Search Template API: endpoint now supports source parameter
- REST Scroll API: Clear scroll should accept scroll_id in body
- REST Scroll API: Throw useful error when invalid scroll_id is specified
- Search stats: Make sure successful operations are counted correct if
