Updating jQuery

What is the preferred method for updating jQuery? Omeka appears to use 1.7.1, and I would like to update to 1.10.0. I am running Omeka 1.5.3.

There's not really a "preferred method."

Omeka generally loads jQuery from the Google CDN, and the path to the current version is hardcoded in the display_js function.

You could also flip on the theme.useInternalScripts config option, then just replace the javascripts/jquery.js file in application/views/scripts, or add the updated one to your theme (if it's just a public-side thing).
