Should there be any major issues to switch from jQuery 1.4.4 to jQuery 1.6.1?
I just noticed that all of the sites on our system were using 1.4.4.
So should i switch them all over to the newest one (1.6.1) or keep them as is, and if i do switch, what issues may I face?
Your safest bet is to go the jQuery Blog and go though the change logs from 1.4.4 to 1.6.1. Change logs call out feature changes that would require you to change your code.
Here’s a sample:
