what happens to hacks when i update to vb3
 

well i've done a lot of modifications to my board (skin, hacks, etc) so when i update to 3.0 will all this stuff work with the new version or will everything need to be reinstalled

They're all gone.

(no offense but) I don't understand why everybody doesn't understand this. Hacks are code modifications, and vB3 is a virtual rewrite, so logically no hacks should work because their instructions would refer to completely rewritten code and database structures.

I was reading some threads at vBulletin.com, I was wondering is it true that a Document will be written by the devs to teach users how to keep or re add some of the modifications? Or did I read it wrong? I also saw a Dev's post saying that many of the hacks for 2.2.x can be installed on vB3, and that its just a matter of figuring out where to plop the coding.

Can anyone confirm this for us (the users)
Thanks

I'm for certain there will be documentation included for developers, or maybe reference posted on one of the vBulletin forums, for a listing of the new variables added/replaced, the new/modified functions, and maybe a walkthrough of the new structure. This is for me and others just about all needed so to upgrade without taking ages to do so. As for a documentation on converting hacks from vB2 to vB3, I don't think this will be done officially, but maybe by the many giving hackers existent on the forum. ;)

I highly recommend using Araxis Merge as well, it makes the task so much incredibly easier. :p
