The Apache Tomcat Project is proud to announce the release of version 10.0.0-M3 of Apache Tomcat. This release is a milestone release and is targeted at Jakarta EE 9.

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.

The notable changes in this release are:

• Disable session persistence by default on restart
• Add new attribute persistAuthentication to both StandardManager and PersistentManager to support authentication persistence. Patch provided by Carsten Klein
• A zero length AJP secret will now behave as if it has not been specified.

Full details of these changes, and all the other changes, are available in the Tomcat 10 (alpha) changelog.
