[ANN] Apache Tomcat 10.1.0-M12 (alpha) available

[Mark Thomas <ma...@apache.org>]

The Apache Tomcat team announces the immediate availability of Apache
Tomcat 10.1.0-M12 (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-M12 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-M11 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.
