Next time you visit the download page you should notice a new type of download available. Upgrade Patches. Now you can generate your own special download that is tailored for upgrading your install.

With the new upgrade patch options you can choose what version you are upgrading from and what type of encoding (zend or ioncube) you use. After making those selections simply click download! The resulting download will only include files that were changed and need to be uploaded.

This should make the process of upgrading much easier for many of our clients. There is no need to scan a changed file list or upload the whole distribution.
Please let us know if you have any comments or questions regarding this!
