Change History
In the history you can see who edited the article and when, and what exactly changed — edits are highlighted right in the text.
Open history
Open the article.
In the article menu, select Show history.
Pick the entry you need — the article shows the edits for that version.

A history entry includes the author's name and email and the date of the change.
How to read edits
Green — added, red strikethrough — deleted.
Highlighting covers the whole document: paragraphs, tables, lists, images, and other blocks.
Deleted text is readable in place: expand it with the marker in the article.
At the bottom there is an edit counter and jumps to the previous and next change.
Only changes collapses paragraphs without edits, so you can walk through all changes faster.
