The Apache Tomcat team announces the immediate availability of Apache
Tomcat 11.0.0-M1 (alpha).

Apache Tomcat 11 is an open source software implementation of the
Jakarta Servlet, Jakarta Server Pages, Jakarta Expression Language,
Jakarta WebSocket, Jakarta Authentication and Jakarta Annotations

Users of Tomcat 10 onwards should be aware that, as a result of the move
from Java EE to Jakarta EE as part of the transfer of Java EE to the
Eclipse Foundation, the primary package for all implemented APIs has
changed from javax.* to jakarta.*. This will almost certainly require
code changes to enable applications to migrate from Tomcat 9 and earlier
to Tomcat 10 and later. A migration tool is under development to aid
this process.

Apache Tomcat 11.0.0-M1 is the first milestone release of the 11.0.x
branch and has been made to provide users with early access to the new
features in Apache Tomcat 11.0.x so that they may provide feedback. The
notable changes compared to 10.1.x include:

- Alignment with the current development versions of the Jakarta
  Servlet, Pages and Expression Language specifications. This includes
  removal of deprecated code and addition of the
  jakarta.servlet.error.query_string attribute for error dispatches

- BASIC authentication now uses UTF-8 by default

- Conversions from bytes to characters now trigger exceptions rather
  than replacement for invalid byte sequences for the given encoding

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