Did that, was greeted with a nice white screen.... Had to roll back the update, which shows how important it is to make a backup of your files BEFORE you update. Unsure what went wrong but had lots of error codes before I closed my browser, such as internal error on command line 47... I guess I'll wait until 1.5.0 is more stable before I update, unless someone knows what I did wrong. (This is where I hope of an answer!)
