So, the bulk of my issues thus far have been pretty simple and I’ve  
isolated and ported over a very lengthy app from 1.8.6 to 1.9.1.

The biggest issues I saw were things like scopes:

Before:

named\_scope :private\_pages,  
:conditions =\> ‘pages.parent\_id IS NULL and pages.subpage\_id IS NULL’,  
:order =\> ‘pages.position’,  
:include =\> {:subpages, :subofsubs}

After:

named\_scope :private\_pages,  
:conditions =\> ‘pages.parent\_id IS NULL and pages.subpage\_id IS NULL’,  
:order =\> ‘pages.position’,  
:include =\> [:subpages, :subofsubs]

… and also the use of string.to\_a in much of my code

Before: new\_array += val.strip).to\_a  
After: new\_array += Array(val.strip)

So, where can I find a solid page or two on a complete list rundown of  
all changes from 1.8.6/1.8.7 to 1.9.x? I would like to keep a reference  
somewhere handy.

Those two :include options are not equivalent. You want:

:include =\> {:subpages =\> :subofsubs}

for the Ruby 1.9 version to be equivalent to the 1.8 version.
