End of Life Announced for Apache Tomcat 5.5

posted by Stacey Schneider on August 10, 2011 08:38 AM

Announced this morning by the Apache Tomcat team:


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
  • The bugzilla project for 5.5.x will be made read-only


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 before 30 September 2012.

Thank you,

-- The Apache Tomcat Team

Tomcat 6.0

What would be the estimated end of support date for Tomcat 6.0 ? Any estimation going by the trend would help.

EOL time lines

The best way to judge it, is to look at past history.
Tomcat 5.0 came out 2003 with a rewrite to Tomcat 5.5 in 2004. So that is how long these releases have lived. Tomcat 6 will most likely be pretty long lived as well, unless there is a major shift in the market and people upgrade to Tomcat 7 faster than anticipated.

Tomcat 6 or Tomcat 7

Hello, we're still running Tomcat 5.5.28. We're thinking about upgrading to Tomcat 6 at least. But, should we consider 7, instead? Is it advisable or possible to go from 5.5 to 7, skipping 6? I've not been able to find any information, pro or con, on this question. So, any help that can be provided would be greatly appreciated.


This is really your personal decision. Even Tomcat developers will have different recommendation here. I would start with Tomcat 6, since it has been stable a lot longer than Tomcat 7. Then it is up to you when you wish to move to 7.

So, one could legitimately go

So, one could legitimately go from 5.5 to 7 if they really wanted to. There's no Tomcat requirement that prevents this? Generally, I try to not skip whole versions. But, in trying to get "caught up", I wondered if it might be useful to consider 7 rather than 6.
