Subject [ANN] Apache Tomcat 8.5.59 available
Date Mon, 12 Oct 2020 09:23:10 GMT
The Apache Tomcat team announces the immediate availability of Apache
Tomcat 8.5.59.

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 replaces 8.0.x and includes new features pulled
forward from the 9.0.x branch. The notable changes since 8.5.58 include:

- Refactor the handling of closed HTTP/2 streams to reduce the heap
  usage associated with used streams and to retain information for more
  streams in the priority tree.

- Deprecate the JDBCRealm.

- Ensure that none of the methods on a ServletContext instance always
  fail when running under a SecurityManager. Pull request provided by
  Kyle Stiemann.

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