[ANN] Apache Tomcat 11.0.15 Available

The Apache Tomcat team announces the immediate availability of Apache 
Tomcat 11.0.15.

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

The notable changes compared to 11.0.14 include:

- Add strictSNI attribute on the Connector to allow matching the
   SSLHostConfig configuration associated with the SNI host name to the
   SSLHostConfig configuration matched from the HTTP protocol host name.
   Non matching configurations will cause the request to be rejected. The
   attribute default value is true, enabling the matching.

- Correct a regression introduced in 11.0.11 that broke some clustering
   configurations.

- Update Commons Daemon to 1.5.0.
