What to consider when upgrading Mods?

[Lynne]

Always read the releases for the new versions of vbulletin. They usually spell out if there is some change in the way something is done. For instance, the addition of the security token for 3.7 was a big deal for some mods. It effected all forms. So, if you know about the security token, then you know to go through any mod you may have installed and make sure this security token is present (sometimes you don't even have to do that, you just need to upgrade the modification).
