[Building Sakai] jQuery 1.1.4 > 1.3.2 Upgrade for 2.7?

[John Norman]

I agree with Nuno that the performance claim is a great motivator. So  
what do we know about how significant the difference would be for our  
application? Is it possible to measure so risk/effort can be balanced  
against expected benefits? I noticed http://ejohn.org/blog/deep-profiling-jquery-apps/ 
  on a quick search and it seems reasonable to suppose that different  
apps would see different effects, but I don't know if this tool allows  
comparison across versions.

In many ways, Eli's offer to fix bugs reduces the risk element  
significantly so this may look like nit-picking, but I just wanted to  
make a general point about evidence for claims and risk/reward trade- 
offs. OTOH there is a lot to be said for "if it ain't broke, don't fix  
it".
