Upgrading to a later Maintenance Release

The third version number is known as a maintenance release and should only ever require a simple update to perform. Maintenance releases never contain any schema changes, and do not require any sort of "updater".

For example, upgrading from 6.0.0 to 6.0.15.

Steps to Upgrade

Make sure you do a complete replace of the ./core directory. Depending on your operating system, just copying over the top of the directory structure will append and replace. This would mean you never delete old and dead files in core, which may have serious repercussions ie. your app breaks. Just be sure to replace the directory structure and all will be well (smile)
