Tomcat 服务器是一个免费的开放源代码的Web 应用服务器，属于轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试JSP 程序的首选。

Tomcat 9.0.0.M26 (alpha) 和 8.5.20 已发布。

Tomcat 9.0.0.M26 (alpha)是 9.0.x 分支的一个里程碑版本，并且已经为用户提供了 Apache Tomcat 9.0.x 中新功能的早期访问，以便他们可以提供反馈。与 9.0.0.M22 相比，有以下的显著变化：

When generating JSP runtime error messages that quote the relevant JSP source code, switch from using the results of the JSP page parsing process to using the JSR 045 source map data to identify the correct part of the JSP source from the stack trace. This significantly reduces the memory footprint of Jasper in development mode, provides a small performance improvement for error page generation and enables source quotes to continue to be provided after a Tomcat restart.
Add LoadBalancerDrainingValve, a Valve designed to reduce the amount of time required for a node to drain its authenticated users
Improve the Default Servlet's handling of static files when the file encoding is not compatible with the required response encoding.
Add support for a Tomcat specific deployment descriptor, /WEB-INF/tomcat-web.xml. This descriptor has an identical format to /WEB-INF/web.xml. The Tomcat descriptor takes precedence over any settings in conf/web.xml but does not take precedence over any settings in /WEB-INF/web.xml.
Add ExtractingRoot, a new WebResourceRoot implementation that extracts JARs to the work directory for improved performance when deploying packed WAR files.
Add support to the WebSocket client for following redirects when attempting to establish a WebSocket connection. Patch provided by J Fernandez.
Add support for the %X pattern in the AccessLogValve that reports the connection status at the end of the request. Patch provided by Zemian Deng.
