Elasticsearch breaking changesedit
This list summarizes the most important breaking changes in Elasticsearch 7.17.20. For the complete list, go to Elasticsearch breaking changes.
Packaging changesedit
The Windows MSI installer package is no longer available.
Details
We no longer release Windows MSI installer packages for Elasticsearch. These packages
were previously released in beta and didn’t receive widespread adoption.
Impact
To install Elasticsearch on Windows, use the .zip archive
package instead.
Cluster and node setting deprecationsedit
Deprecation for truststores with no trust entries
Details
The use of SSL truststores that do not contain any trusted entries has been deprecated.
The various *.ssl.truststore.path settings (for example
xpack.security.transport.ssl.truststore.path or xpack.http.ssl.truststore.path) can
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
Impact
To avoid deprecation warnings, remove any SSL truststores that do not
contain any trusted entries.
Mapping deprecationsedit
Camel case date formats are deprecated.
Details
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.
Impact
To avoid deprecation warnings, discontinue use of the camel case pattern.
