I just made a change to the file structure for our .tar.gz and .zip downloads that will affect 13.3.

For many releases, we split JAR files into two separate subdirectories, ./server-lib and ./common-lib. The distinction was important for Tomcat 5.5, which had corresponding ./server/lib and ./common/lib directories for its file (and classloader) layout. We no longer support Tomcat 5.5, and Tomcat 6 and 7 have a single ./lib directory. Therefore, we've consolidated the two directories into a single ./tomcat-lib directory in our distributions.

Our Windows installer and Linux upgrade scripts will automatically work with the new layout. f you have a different upgrade process, you may need to update your scripts or your manual workflow. Instead of pulling files from both server-lib and common-lib, you'll just need to pull them from the tomcat-lib directory.

Let us know if you have any questions.

Thanks,
Josh
