Revisions


Real fast basic talk about revisions now that I’m super popular and reaching upwards of three people. A revision is just a saved copy of a post or page that is saved in the database. It is often popular to limit the number of revisions you are allowed cause you can go crazy. Some of my pages have upwards of 60 revisions cause I make a lot of mistakes.

When Do Revisions Get Saved?

If you start a new post, you have zero revisions. If you make a change and update that post you then have two revisions, the change, and the pre-change. Every time you hit the update button and there has been a change, it will make a revision. If you have the option to limit revisions then the oldest one is going to be deleted.

They are special though, they always have a slot and they don’t take up one of your revisions slots. They are saved in the database somewhere but also in the browser somewhere.
