Changelog:
 The Apache Tomcat Project is proud to announce the release of version 7.0.47 of \ 
Apache Tomcat. This release contains a number of bug fixes and improvements \

    Back-port the JSR-356 Java WebSocket 1.0 implementation from Apache Tomcat \ 
8. Note that use of this functionality requires Java 7.
    Deprecate the Apache Tomcat proprietary WebSocket API in favour of the new \ 
JSR-356 implementation.
    Add a drawing board example to the WebSocket examples.
    The minimum required APR/native library version required if the APR/native \ 
connector is used is now 1.1.29.
