The Apache Tomcat Project is proud to announce the release of version 10.1.30 of Apache Tomcat. This release implements specifications that are part of the Jakarta EE 10 platform.
Apache Tomcat 项目自豪地宣布发布 Apache Tomcat 的 10.1.30 版本。此版本实施了属于 Jakarta EE 10 平台的规范。

Applications that run on Tomcat 9 and earlier will not run on Tomcat 10 without changes. Java EE based 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.
在 Tomcat 9 及更早版本上运行的应用程序如果不进行更改，将无法在 Tomcat 10 上运行。为 Tomcat 9 及更早版本设计的基于 Java EE 的应用程序可以放在 $CATALINA_BASE/webapps-javaee 目录中，Tomcat 会自动将它们转换为 Jakarta EE 并将它们复制到 webapps 目录。此转换是使用 Apache Tomcat Migration Tool for Jakarta EE 工具执行的，该工具也可单独下载以供离线使用。

The notable changes in this release are:
此版本中的显著变化包括：

• Fix the regression in HTTP/2 support introduced in 10.1.29.

The Apache Tomcat Project is proud to announce the release of version 11.0.0-M26 (beta) of Apache Tomcat. This release is a milestone release and is targeted at Jakarta EE 11.
Apache Tomcat 项目自豪地宣布发布 Apache Tomcat 版本 11.0.0-M26（测试版）。此版本是一个里程碑版本，面向 Jakarta EE 11。

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 available to aid this process.
Tomcat 10 及更高版本的用户应该知道，由于从 Java EE 迁移到 Jakarta EE，作为 Java EE 转移到 Eclipse Foundation 的一部分，所有已实现的 API 的主包都已从 javax.* 更改为 jakarta.* 。这几乎肯定需要更改代码，以使应用程序能够从 Tomcat 9 及更早版本迁移到 Tomcat 10 及更高版本。可以使用迁移工具来帮助此过程。

The notable changes in this release are:
