Subject [ANN] Apache Tomcat 8.5.20 available
Date Wed, 09 Aug 2017 17:52:04 GMT
The Apache Tomcat team announces the immediate availability of Apache
Tomcat 8.5.20.

Tomcat 8.x users should normally be using 8.5.x releases in preference
to 8.0.x releases.

Apache Tomcat 8 is an open source software implementation of the Java
Servlet, JavaServer Pages, Java Unified Expression Language, Java
WebSocket and Java Authentication Service Provider Interface for
Containers technologies.

Apache Tomcat 8.5.x is intended to replace 8.0.x and includes new
features pulled forward from the 9.0.x branch. The notable changes since
8.5.16 include:

- Add the ability to set the defaults used by the Windows installer from
  a configuration file. Patch provided by Sandra Madden.

- Add support to the WebSocket client for following redirects when
  attempting to establish a WebSocket connection. Patch provided by J

- Add support for the %X pattern in the AccessLogValve that reports the
  connection status at the end of the request. Patch provided by Zemian

Please refer to the change log for the complete list of changes:
