There are notable differences between the JBoss EAP product and the continuous delivery release for JBoss EAP.

Elytron Audit Logging Performance and Reliability Tuning

In JBoss EAP 7.2, the synchronized attribute for Elytron file audit logging defined whether to flush the output stream and synchronize the file descriptor after every audit event.

This release introduces a new autoflush attribute to separate stream flushing and file synchronizing, which allows for finer tuning of performance and reliability for Elytron audit logging.

For more information on configuring Elytron audit logging, see Elytron Audit Logging in How to Configure Server Security for JBoss EAP.

JwtValidator Enhancements

The JwtValidator in this release now includes support for multiple keys and for remote public keys. The key-store attribute can now be combined with the certificate attribute to be used as an alternate to the public-key. The client-ssl-context attribute defines the SSL context to use for a remote JSON Web Key (JWK). This enables you to use the URL from the jku (JSON Key URL) header parameter to fetch public keys for token verification.

For more information, see the token-realm jwt Attributes table in How to Configure Server Security for JBoss EAP.

Default SSLContext

This release now registers a default SSLContext on startup that is available for use by any libraries that support use of the default context.

For more information, see Default SSLContext in How to Configure Server Security for JBoss EAP.

Java Authentication SPI for Containers (JASPI) Security Using Elytron

The elytron subsystem in this release now provides an implementation of the Servlet profile from the Java Authentication SPI for Containers (JASPI). This allows tighter integration with the security features provided by Elytron.

For more information, see Configure Java Authentication SPI for Containers (JASPI) Security Using Elytron in the Development Guide for JBoss EAP.

Server SSL Server Name Indication (SNI) Contexts

The server-ssl-sni-context in this release is used for providing server-side SNI matching. It provides matching rules to correlate host names to SSL contexts, along with a default in case none of the provided host names are matched.

For more information, see Using a server-ssl-sni-context in the How to Configure Server Security for JBoss EAP.

Support for Eclipse MicroProfile Metrics

This release now includes the SmallRye Metrics component, which provides Eclipse MicroProfile Metrics functionality using the microprofile-metrics-smallrye subsystem. This subsystem is used to provide monitoring data for the JBoss EAP instance, and is enabled by default.

For more information, see Eclipse MicroProfile Metrics in the Configuration Guide for JBoss EAP.

Disable Output Paging

By default, the JBoss EAP management CLI pauses after a page of output has been displayed, which allows you to browse and search the command output. You can now disable this behavior and print the entire output immediately by starting the management CLI with the --no-output-paging argument or by setting the output-paging element to true in the EAP_HOME/bin/jboss-cli.xml file.

Support for some technologies are removed due to the high maintenance cost, low community interest, and better alternative solutions. This release does not introduce any newly unsupported features.

However, the unsupported features listed in the Unsupported Features section of the release notes for JBoss EAP 7.2 also apply to this continuous delivery release for JBoss EAP, unless they are mentioned in the New Features and Enhancements section of this document.

Some features have been deprecated with this release. This means that no enhancements will be made to these features, and they may be removed in the future, usually the next major release.

Red Hat will continue providing full support and bug fixes under our standard support terms and conditions. For more information about the Red Hat support policy, see the Red Hat JBoss Middleware Product Update and Support Policy located on the Red Hat Customer Portal.

For details of which features have been deprecated, see the JBoss Enterprise Application Platform Component Details located on the Red Hat Customer Portal.
