Breaking changes in 1.6

This section discusses the changes that you need to be aware of when migrating your application from Elasticsearch 1.x to Elasticsearch 1.6.

The More Like This API query has been deprecated and will be removed in 2.0. Instead use the More Like This Query.

The top_children query has been deprecated and will be removed in 2.0. Instead the has_child query should be used. The top_children query isn’t always faster than the has_child query and the top_children query is often inaccurate. The total hits and any aggregations in the same search request will likely be off.

Locations of file system repositories has to be now registered using path.repo setting. The path.repo setting can contain one or more repository locations:

path.repo: ["/mnt/daily", "/mnt/weekly"]

If the file system repository location is specified as an absolute path it has to start with one of the locations specified in path.repo. If the location is specified as a relative path, it will be resolved against the first location specified in the path.repo setting.

Starting with version 1.6.1 URL repositories with http:, https:, and ftp: URLs has to be whitelisted by specifying allowed URLs in the repositories.url.allowed_urls setting. This setting supports wildcards in the place of host, path, query, and fragment. For example:

repositories.url.allowed_urls: ["http://www.example.org/root/*", "https://*.mydomain.com/*?*#*"]
