Old DP4 Releases

Information about pre 4.620 releases of DP4 has been removed to this part of the DP4 web site as it is now mostly very old, and the way the information was presented could be confusing to users of newer releases.

Here are the pages listing the bug fixes and enhancements available for releases 4.617/4.521 through to 4.619 and release 4.523.

Here are the pages listing bug fixes and enhancements available for release 4.520/4.616 and earlier:

I would strongly recommend anyone still running release 4.619 or earlier to consider upgrading to release 4.621(or 4.525 for Linux) unless you are completely satisfied with your current DP4 set up. Performance of 4.621 is very significantly better than that of 4.619 or earlier releases. Releases prior to 4.619 are not supported on Windows XP or Windows 2003. No enhancements available in 4.620 or later releases will be made available for these old DP4 releases, and only critical bugs will be fixed if any should arise.
