### Plugin Updated: WP Memcached

When wp_cache_get_multiple() is called with more than 1000 keys, the lookups will
be split up into multiple batches. This helps keep the Memcached servers stable,
as otherwise the read/response buffers can grow uncontrollably large.

### Plugin Updated: Enterprise Search

Fix type error when a callable passed to `ep_weighting_configuration_for_search`,`
ep_query_weighting_fields`, `ep_weighting_configuration`, or `ep_weighting_fields_for_post_type`
is not a method.

### Plugin Updated: Query Monitor APCu Cache

Fix broken markup when the APCu cache is not enabled.
