I've noticed that attached images used to be uploaded to /public_html/webbbs/images and now they upload to /public_html/webbbs/images/main. And I'm guessing the change occurred about the same time I upgraded to 5.30b1?

Was that intentional ... or did I inadvertently change something?

Reason I ask is because I like to keep everything in one directory for backup purposes and this change confused me ...
