Please NOTE:

I would suggest all implementors consider updating to Apache Tomcat 7.0 or higher.

Apache Tomcat installations of 5.5 or lower would be considered a significant security risk.

 The Apache Tomcat team announces that support for Apache Tomcat 5.5.x
> will end on 30 September 2012.

> This means that after 30 September 2012:
> - releases from the 5.5.x branch are highly unlikely
> - bugs affecting only the 5.5.x branch will not be addressed
> - security vulnerability reports will not be checked against the 5.5.x
> branch
>
> Three months later (i.e. after 31 December 2012)
> - the 5.5.x download pages will be removed
> - the latest 5.5.x release will be removed from the mirror system
> - the 5.5.x branch in svn will move from /tomcat/tc5.5.x to
> /tomcat/archive/tc5.5.x
> - the links to the 5.5.x documentation will be removed from
> tomcat.apache.org
> - The bugzilla project for 5.5.x will be made read-only

This has all been completed.


> Note that all 5.5.x releases will always be available from the archive.

> It is anticipated that the final 5.5.x release will be made shortly

The final release was 5.5.36 on 10 Oct 2012 and is, and will always
remain, available from the archives.
