Aligned reporting of index statistics that exist in the current cluster state.
This fix avoids subtle race conditions in stats reporting.
Fixed handling of comments in XML documents [ESA-2018-07].
Fixed auditing such that when you use a local audit index, it maintains the
mappings automatically. Maintenance is necessary, for example, when new fields
are introduced or document types change.
Added and changed settings for the SAML NameID policy. For example, added the
nameid.allow_create setting and changed the default value for
the SPNameQualifier setting to blank. See SAML Authentication.
Fixed handling of an Assertion Consumer Service (ACS) URL with existing query
parameters. See SAML Authentication.
Fixed the PKI realm bootstrap check such that it works with secure settings.
For more information, see Bootstrap Checks.
Fixed the serialization of failed hipchat messages, such that it no longer
tries to write the status field twice.
