The Apache Tomcat team announces the immediate availability of Apache
Tomcat 11.0.0-M9 (alpha).

Apache Tomcat 11 is an open source software implementation of the
Jakarta Servlet, Jakarta Server Pages, Jakarta Expression Language,
Jakarta WebSocket, Jakarta Authentication and Jakarta Annotations

Users of Tomcat 10 onwards should be aware that, as a result of the move
from Java EE to Jakarta EE as part of the transfer of Java EE to the
Eclipse Foundation, the primary package for all implemented APIs has
changed from javax.* to jakarta.*. This will almost certainly require
code changes to enable applications to migrate from Tomcat 9 and earlier
to Tomcat 10 and later. A migration tool is available to aid this process.

Apache Tomcat 11.0.0-M9 is a milestone release of the 11.0.x branch and has been made to provide users with early access to the new features in Apache Tomcat 11.0.x so that they may provide feedback. The notable changes compared to 11.0.0-M7 include:

- Add ContextNamingInfoListener, a listener which creates context naming
  information environment entries

- Add PropertiesRoleMappingListener, a listener which populates the
  context's role mapping from a properties file.

- Update the Jakarta EL and Jakarta WebSocket implementations to align
  with the latest changes planned for Jakarta EE 11

Please refer to the change log for the complete list of changes:
