Apache Tomcat 8.0.0-RC10 (alpha) 发布，Apache Tomcat 8 是跟 Java EE 7 同步的，同时还支持规范性的 Java EE 更新版本。Tomcat 8 包括很多更新内容，突出的更新内容如下：
- Support for Java Servlet 3.1, JavaServer Pages 2.3, Java Unified Expression Language 3.0 and Java WebSocket 1.0. - The default connector implementation is now the Java non-blocking implementation (NIO) for both HTTP and AJP. - A new resources implementation that replaces Aliases, VirtualLoader, VirtualDirContext, JAR resources and external repositories with a single, consistent approach for configuring additional web application resources. The new resources implementation can also be used to implement overlays (using a master WAR as the basis for multiple web applications that each have their own customizations).
Apache Tomcat 8.0.0-RC10 还包括修复一些在 RC5 证实存在的问题，还有一些改进，主要更新内容如下：
- Extending the new resources implementation to include resource handling for class loaders and the addition of a new feature to track the code responsible for an open file.
- Complete refactoring of TLD handling including the addition of caching of parsed TLDs to improve performance.
- Improvements to JMX MBeans including better visibility of DBCP
connection pools and improved organisation in the default JConsole
