| MongoDB 6.0 添加了一项名为“前像/后像记录”的功能。具体而言，它会在每个更改发生前后，记录该更改前、更改后的完整文档信息，并和变更关联以便查阅。 |

Change Streams with Document Pre- and Post-Images
Starting in MongoDB 6.0, you can use change stream events to output the version of a document before and after changes (the document pre- and post-images):The pre-image is the document before it was replaced, updated, or deleted. There is no pre-image for an inserted document.
The post-image is the document after it was inserted, replaced, or updated. There is no post-image for a deleted document.
Enable changeStreamPreAndPostImages for a collection using db.createCollection(), create, or collMod.
I think we should add some reference the change stream documentation here to help user know how to enable pre-and-post images feature.
