The Apache Tomcat Project is proud to announce the release of version 10.0.0-M8 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:

• For requests containing the Expect: 100-continue header, optional support has been added to delay sending an intermediate 100 status response until the servlet reads the request body, allowing the servlet the opportunity to respond without asking for the request body. Based on a pull request by malaysf.
• Add support for a read idle timeout and a write idle timeout to the WebSocket session via custom properties in the user properties instance associated with the session. Based on a pull request by sakshamverma.
• Update the packaged version of the Tomcat Native Library to 1.2.25

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