Apache Tomcat 5.5 Servlet/JSP 容器

Project Status

本文的意图是为各位介绍Tomcat开发的现状，而没有提供有关某个臭虫是否已经被改正或 Tomcat是否支持某个功能。

This page is updated roughly once per every couple of Tomcat minor releases, so for day-to-day status you should check the tomcat-user and tomcat-dev mailing lists. You can always inquire there as to the availability or status of a specific feature or component.

Tomcat 5.0.27 在2004 年6月17日发表。 那时起 TOMCAT_5_0 在 CVS 里面开始分枝， Tomcat 5.5正是开始开发。 Tomcat 5.5 已经发表了几个稳定版。Tomcat 5.5是现在所有工作的 重点。Tomcat 5.0只是处于维护状态，它的修正版会发表的越来越少。

Tomcat 5.5 有几个主要目标。可以从下面的连接看到。 MARC. The status of some of these items is detailed below. Once 5.5 releases are available, please refer to the Changelog accompanying each release for detailed changes, enhancements, and fixes.

Tomcat 4.1.x is no longer actively developed. It is maintained to address only showstopper, security, and Servlet Specification compliance issues. Maintenance for Tomcat 4.1.x will likely cease once a stable release or two of Tomcat 5.5 are out. Users of Tomcat 4.1.x are strongly encouraged to upgrade to the latest stable Tomcat 5.0 release.

Tomcat 4.0.x is relatively old, and not actively maintained or supported. It is strongly recommended that users of these releases upgrade to the latest stable Tomcat 5.0 release or at least the latest stable Tomcat 4.1 release.

Tomcat 3.3.x is in roughly the same maintenance mode as Tomcat 4.1.x.

Tomcat 3.2 and earlier are in roughly the same support state as Tomcat 4.0.x. Users should upgrade to Tomcat 3.3.x or the latest stable Tomcat 5.0.x.

The columns in this report contain the following information:

• Priority - A sense of how important it is to address this issue in the short term.
• Action Item - Concise description of the action item to be completed. Where relevant, Java package names of the primary classes involved are listed in [square brackets]
• Volunteers - Login of those developers who have volunteered to assist in the design, implementation, testing, and documentation of this action item's changes to Tomcat.

Developers can nominate themselves to work on particular action items by asking a Committer to add their name address to those items. The developers working on each item should discuss and agree upon the approach to be used for implementing the item's changes to the project source code and documentation, prior to completing those changes. Such discussions should take place on the tomcat-dev mailing list so that everyone can stay apprised of what is going on, or chime in if they want to contribute ideas and suggestions.
