Why would you be interested in an older version?

This is a good question. I think you should not, unless you found an old simulation that can not be read with the latest version. 

Version 3.3 was a very good one, if only 3.4 updated it.

Version 3.2 never saw light. It was used for internal purposes only.

Version 3.1 was the first totally finished, with complete documentation and rather widely used.

Version 3.0 is an ancestor of it that also works pretty well. Obviously, 3.1 is more advanced.

Version 2.1 has a good peculiarity. Simulations generated with it run in any browser with no need to install any plug-in. But be warned, if you use it, you will not be able to upgrade to version 3.0, unless you rewrite your simulations.

Earlier versions provided the ideas for these two but are not recommended.

However, they are kept here for nostalgic reasons :-)

Older versions 

Software

• Easy Java Simulations 3.3 (updated December 2004, aprox. 4.9 Mb. ZIP Windows file) 

It is backwards compatible up to version 3.0.

Important notice: If you downloaded Ejs 3.3 before December 4th, 2004, you should upgrade right now. Recent  releases solve a compatibility problem with Apple MacIntosh computers that cause the generated HTML files for the simulations not to be read correctly by Safari (the standard Web browser in recent versions of MacOSX). You should upgrade even if you are not a MacIntosh user.
