I am trying to upgrade from CI version 1.7.3 to CI Version 3.1.7. The problem I have is for some unknown reason the User Guide for 3.1.7 DOES NOT even mention upgrading from version 1.7.3 to version 2.0-let alone upgrading from 1.7.3 to version 3.1.7. How can I get a list of changes made from version 1.7.3 to 3.1.7, IF codeigniter's own user's guide does not even MENTION my version?

I do remember reading something about changing CI version 1.7.2 to version 1.7.3, but then, I am not sure if that means I should follow the upgrade steps for 1.7.2?

So, if I am to follow the steps to upgrade from 1.7.2 to 2.0 then what was the point of upgrading to 1.7.3 to begin with? Any ideas would be greatly appreciated.

Thanks in advance!
