Apache Tomcat發布8.0.9版本，同時這個版本也是8.0的***個stable版本。Tomcat 8需要至少JDK7以上。

值得注意的更新如下：

• 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 8.0.9 包括了 8.0.8 版本的 bug 修復和大量改進，相對于 8.0.8 版本：

• Start to move towards RFC6265 for cookie handling
• Better error handling when the error occurs after the response has been      committed
• Various Jasper improvements to make it easier for other containers (e.g.      Jetty) to consume
