want to show filed change history

[jeongmin lee]

At issue page, we can see history

but there are not enough.

I can not know how to be changed in any kind of fileds and value

for example, when i change the due date, i want to see like below 

change due date value 2016-11-02 to 2016-12-05

That is the data captured in the issue history.  Every line in the issue history contains field/from/to and these lines are grouped by change author and date

Some people, for utterly dumb reasons, hack their JIRA to hide or even destroy that data.  That's the only reason I can think of that you might not be seeing it
