Deprecation for truststores with no trust entries
The use of SSL truststores that do not contain any trusted entries has been deprecated. The various
*.ssl.truststore.path settings (for example
be used to configure a set of "trust anchors" for SSL certificate verification. In Elasticsearch
version 7 and earlier, it was permitted to configure a truststore that did not contain
any trust anchors (that is, it was empty, or it contained "private key" entries only).
In Elasticsearch version 8 and above, a
truststore.path without any trusted certificate entries
is no longer accepted, and will cause an error. This configuration is now deprecated in
Elasticsearch version 7.17
To avoid deprecation warnings, remove any SSL truststores that do not contain any trusted entries.
Camel case date formats are deprecated.
The use of camel case patterns on date formats is deprecated and will be removed in Elasticsearch 8.0.0.
The corresponding snake case pattern should be used instead.
To avoid deprecation warnings, discontinue use of the camel case pattern.
