How to compare History of Edits for a line or feature ?

Hi,

I made a plenty of edits in my area for a long time…

But today I noticed someone made a lot of edits yesterday of roads that I made edits on them from a long time !!!

I need to know how to compare the edits on a road to know what this user made and why !!

And how to restore these changes made by this user to previously good status before he made anything.

Thanks

See OSM Changeset Analyzer or maybe other quality assurance tool

You can revert changes using JOSM.
