[ANN] Apache Tomcat 10.1.0-M8 (alpha) available

The Apache Tomcat team announces the immediate availability of Apache
Tomcat 10.1.0-M8 (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-M8 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-M7 include:

- Limit cookie support to RFC 6265 to align with recent updates to the
   Servlet specification

- Update the WebSocket API packaging to remove the copy of the client
   API from the server API and replace it with a dependency on the client
   API. This aligns Tomcat with changes in the WebSocket 2.1
   specification.

- Provide protection against a known OS bug that causes the acceptor to
   report an incoming connection more than once.
