We have just upgraded from Mantis 1.1.7 to MantisBT 1.2.4

and some users have noticed that 'category' no longer appears on any of the reports (we have quite alot of tailored reports)

I dug around in the code and config files and found something called 'category_id'

Does anyone know if these are one and the same? and if so why it changed names?

Is there anyway to bulk change all of our references?
