The Apache Tomcat team announces the immediate availability of Apache
Tomcat 10.1.0-M4 (alpha).
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
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 $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 10.1.0-M4 is a milestone release of the 10.1.x branch and
has been made to provide users with early access to the new features in
Apache Tomcat 10.1.x so that they may provide feedback. The notable
changes compared to 10.1.0-M2 include:
- The minimum Java version has been increased to Java 11 to align with
the plans for the Jakarta EE 10 platform
- Correct a regression in the previous release in the HTTP/2 flow
control window management
- Enable EL lambda expressions to be coerced to functional interfaces.
This is an implementation of a proposed extension to the Jakarta
Expression Language specification.
