The Apache Tomcat team announces the immediate availability of Apache
Tomcat 10.0.17.

This release is targeted at Jakarta EE 9.

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 $CATALINA_BASE/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 is an open source software implementation of the
Jakarta Servlet, Jakarta Server Pages, Jakarta Expression Language,
Jakarta WebSocket, Jakarta Authentication and Jakarta Annotations

The notable changes compared to 10.0.16 include:

- Add support for additional user attributes to TomcatPrincipal and

- Correct a regression in the fix for 65454 that meant that
  minSpareThreads and maxThreads settings were ignored when the
  Connector used an internal executor

- Improve the detection of the Linux duplicate accept bug and reduce
  (hopefully avoid) instances of false positives.

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