I have one confusion and would be extremely grateful if some clarification is offered.
This is a api request I prepared using mediawiki sandbox tool to get 30 sequential edits for the page Sachin Tendulkar. If you run the query in your browser you will see a diff field for each edit
which probably is the difference between past and current edit. Here revision content field is false
This is the same request with content filed true
Now What I see is that for all 30 revision content field is more or less same and right now I am not able to understand what is the reason for the content field. If you know anything regarding this please let me know , I am also trying to understand this field.
