The Apache Tomcat team announces the immediate availability of Apache
Tomcat 10.1.20.

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

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 10.1.20 is a bugfix and feature release. The notable changes compared to 10.1.19 include:

 - Fix regression when reloading TLS configuration and files.

 - When restoring a saved POST request after a successful FORM
   authentication, ensure that neither the URI, the query string no
   the protocol are corrupted when restoring the request body.

 - Align error handling for Writer and OutputStream. Ensure use of
   either once the response has been recycled triggers a
   NullPointerException provided that discardFacades is configured with
   the default value of true.

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