Well that was easy I just did an experiment on my development domain http://www.unseen.org.au to see what would happen if I copies over all the newer files from 2.0.16 to 2.0.18.1.. I removed main.php and logo.gif that was about it as well as the /install path before doing it.

All I had to do was update the system module in admin -> modules -> update and it all seems to be working fine with a new version.

There is around 240 files that have changed.. Whooo that is a bit of typing..

Hi wishcraft

Thank for this feedback.

Note: if you cannot log in when doing this, you will need to replace 2.0.18.1 /include/checklogin.php with the 2.0.16 or same version you have to log in.. Then update the system admin module and remove all your templates from /template_c as the /class/smarty/core has moved to /class/smarty/internals; then you have to put the new version of checklogin.php back in place.
