So I am on NGui 2.2.6c (paid version), and I am going to finally bite the bullet and try for 3.x+.
That being said, I figured the best thing to do was to update first to 2.7 before updating to 3.x+ in order to have a stable 2.7 build in case 3.x ends up being a real PIA. The reason I am hesitant to update to 3.x on my first try is for two reasons:
1) I have written hundreds of custom UI components. The UI is quite complex, and I don't have the energy going down an upgrade rabbit hole right now if it ends up being a pain. That being said, the improvements for depth handling among others will send me down this path at some point for 3.x.
2) I don't know if it is a good idea to upgrade directly from 2.2.6c as the upgrade tutorials were likely written with 2.7 in mind and might not cover deprecated functionality from my older version of 2.2.6c.
So I see references to GitHub and access to the older versions. I have scoured the forums, my email, and the install of NGui I have for a reference on how to access it but to no avail. Where is this information or what do I need to do to request it?
