Can you see when a Project changed to a certain category?

[WiggleDavidYoung]

We have a project category of "Closed".  I'd like to know when the project category for a particular project was changed to this.  Can this be done?

there's a ProjectUpdatedCategoryChangedEvent, so if you have eg Scriptrunner you can create a listener to catch it and say notify you if category got changed to the one you desire
