The Apache Tomcat Project is proud to announce the release of version 10.0.0-M9 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:

• Refactor the handling of closed HTTP/2 streams to reduce the heap usage associated with used streams and to retain information for more streams in the priority tree.
• Allow using the utility executor for annotation scanning. Patch provided by Jatin Kamnani.
• Add a bloom filter to speed up archive lookup and improve deployment speed of applications with a large number of JARs. Patch provided by Jatin Kamnani.

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