The Apache Tomcat team announces the immediate availability of Apache
Tomcat 10.0.18.

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 10.0.17 include:

- Fix a potential thread-safety issue that could cause HTTP/1.1 request
  processing to pause, and potentially timeout, waiting for additional
  data when the full request has been received.

- Fix a regression introduced with 65757 bugfix which better identified
  non request threads but which introduced a similar problem when user
  code was doing sequential operations in a single thread.

- When resolving methods in EL expressions that use beans and/or static
  fields, ensure that any custom type conversion is considered when
  identifying the method to call.
