Summary of Changes Since 2.4.x

Enhancements

Added Java 9/10/11/12 support
Introduced new jar, applicationinsights-web-auto.jar, which automatically registers the web filter. No need to modify web.xml or add @WebFilter.
Simplifies role name configuration by adding <RoleName> tag in ApplicationInsights.xml.

Generic JDBC driver support: captures JDBC queries for all JDBC drivers.
Automatically captures dependencies for async requests by tracking the request across multiple threads.
Agent now captures application logging from Log4j 2/1.2 and Logback.
- This removes the need to add the applicationinsights-logging-*.jar dependency and modify the application's logging configuration.
Improved HTTP client support:
- java.net.HttpURLConnection
- Apache HttpClient 3.x
- OkHttp3
- OkHttp2 now supports distributed tracing
Sets Operation Name automatically based on Spring @RequestMapping, JAX-RS @Path and Struts action class/method name.
- This removes the need for RequestNameHandlerInterceptorAdapter or other interceptors.
Agent now supports multiple applications deployed in the same application server (temporarily in the 2.4.0)
Simplified JBoss and Wildfly deployment when using the agent: no need for workarounds using jboss.modules.system.pkgs, java.util.logging.manager, -Xbootclasspath
Added agent logging capture threshold, configurable via <Logging threshold="warn" />
in the AI-Agent.xml, with default threshold warn (#1026)

Removed support for <RuntimeException> custom instrumentation in AI-Agent.xml

#969 Fixes ability to configure Live Metrics iKey programatically.
#978 Possible NPE during development
