The Apache Tomcat team announces the immediate availability of Apache 
Tomcat 10.1.55.

Apache Tomcat 10 is an open source software implementation of the 
Jakarta Servlet, Jakarta Pages, Jakarta Expression Language, Jakarta 
WebSocket, Jakarta Authentication and Jakarta Annotations specifications.

Applications that run on Tomcat 9 and earlier will not run on Tomcat 10 
without changes. Java EE applications designed for Tomcat 9 and earlier 
may be placed in the /webapps-javaee directory and Tomcat will 
automatically convert them to Jakarta EE and copy them to the webapps 
directory. This conversion is performed using the Apache Tomcat 
migration tool for Jakarta EE tool which is also available as a separate 
download for off-line use.

Apache Tomcat 10.1.55 is a bugfix and feature release. The notable 
changes compared to 10.1.54 include:

  - Enhance version.sh and version.bat to display APR, Tomcat Native, and
    OpenSSL version information.

  - Free private keys, keys and certificates after use in FFM based
    connector configuration.

  - Various HTTP/2 validation improvements and a broader change to use
    stream resets rather than connection closures where appropriate.
