find the latest version of jquery programatically

find the latest version of jquery programatically

Hi! I was wondering if there was a clean way to get the latest version of jQuery programatically. I simply want to get the latest version number to compare against my present version so I can implement and test the new version for stability across my clients without needing to F5 https://jquery.com/download/ to check for new versions. 

I write in PHP primarily, and a simple cron script to ping a server each day to check for new version is ideal. Maybe a jQuery call already exists for similar purposes, but no amount of Google has been useful. 

Any ideas?
