[[breaking_710_search_changes]]
=== Search Changes
[discrete]
==== Missing checks for `index.max_docvalue_fields_search`
The setting `index.max_docvalue_fields_search` limits the number of fields that
can be retrieved through `docvalue_fields` in a search. Previously we only
checked this limit when `docvalue_fields` appeared in the top-level search
request body. Now we also enforce the limit when loading doc value fields in
an `inner_hits` section or in a `top_hits` aggregation.

[[breaking_710_networking_changes]]
=== Networking Changes
[discrete]
==== *.tcp.keep_idle and *.tcp.keep_interval now bounded
The settings `{network,transport,http}.tcp.keep_idle` and
`{network,transport,http}.tcp.keep_interval` are now limited to a maximum
value of 300, which amounts to 5 minutes. This helps ensure that, if
explicitly configured, only reasonable values are set.
