Sounds really really great ! I don't need this script but just want to say you "Good job and thanks for the sharing!!!"

I really liked the sound of this script, and the code looks good, however, I tried to update a site from 3.3.3 to 3.4.3 and it just returned "This Joomla version cannot be updated. Exiting.".

I think this is just because maybe the newer Joomla versions do things a little differently, but I'll try and see if I can fix it.

It's now built into Akeeba and myjoomla.com for automatic updating.

Hi @renekreijveld, @xpallicer and @AndyGaskell did you guys fix this? I'm trying to fix this too, because all versions between 3.2 and 3.4.8 have security issues.
